Description

The present invention relates to an information providing server, an information providing system, an information providing method, and a program.

Conventionally, subtitle information encouraging evacuation in the event of a disaster or the like has been displayed on television screens. However, the subtitle information encouraging evacuation displayed on television screens is usually displayed on a city, ward, town, or village basis. In other words, in a city, ward, town, or village where evacuation of residents is encouraged, there may be areas where evacuation is not necessary as well as areas where evacuation is truly necessary.
Therefore, based solely on the subtitle information displayed on a television screen, residents of municipalities where evacuation is being encouraged cannot accurately determine whether their homes are located in an area where evacuation is truly necessary, or whether their homes are in an area where evacuation is not necessary.

Further, detailed information indicating areas subject to weather or disaster warnings, such as landslide warning information issued by the Japan Meteorological Agency and landslide warning determination mesh information (information that indicates the increased risk of landslides caused by heavy rain in five levels of color for each 5 km square mesh area), has been provided. If landslide warning determination mesh information were provided to each resident of a city, ward, town, or village where evacuation is being encouraged, each resident would be able to accurately determine, based on the landslide warning determination mesh information, whether their home is in an area where evacuation is truly necessary or whether their home is in an area where evacuation is not necessary.
However, many residents of municipalities that were urged to evacuate in the past were unaware that the Japan Meteorological Agency had released detailed information such as landslide warning information and landslide warning mesh information, and have no experience of using such information.
Furthermore, when there are only a few mesh areas within a city, ward, town, or village from which residents need to evacuate (for example, mesh areas indicating a risk level of "extremely dangerous"), the reality is that although information encouraging evacuation should be conveyed to the residents within those mesh areas, subtitle information encouraging evacuation to the residents of the city, ward, town, or village that includes those mesh areas is not displayed on the television screen.

Patent Literature 1 describes a disaster prevention information distribution system that distributes disaster prevention information to a mobile information terminal. In the technology described in Patent Literature 1, disaster prevention information is distributed to a mobile information terminal of a user.
Incidentally, in the technology described in FIG. 9 of Patent Document 1, the disaster prevention information delivered to the user's mobile information terminal is, "Landslide warning: There is an 80% risk of occurrence within two hours,""Target location: Naoto School," and "Those who will need time to evacuate are advised to begin evacuating immediately."
In other words, the technology described in Patent Document 1 informs the user that there is an 80% risk of a landslide occurring within two hours, but does not provide the user with information on the size of the area in which there is an 80% risk of a landslide occurring within two hours. In other words, the technology described in Patent Document 1 does not provide the user with detailed information such as landslide warning determination mesh information.
Therefore, although the technology described in Patent Literature 1 allows a user to know that he or she belongs to a city, ward, town, or village where evacuation is encouraged, the user cannot accurately determine whether he or she belongs to an area where evacuation is truly necessary or an area where evacuation is not necessary. In other words, the technology described in Patent Literature 1 does not allow a user to accurately determine the situation, such as whether or not evacuation is truly necessary.

Patent Document 2 describes a gardening consultant system that appropriately provides necessary cultivation information to a user. In the technology described in Patent Document 2, appropriate cultivation information is generated from corresponding information previously stored in an information server based on user information, and the cultivation information is transmitted to a user terminal.
However, in the technology described in Patent Document 2, the information transmitted to the user terminal is cultivation information, so even with the technology described in Patent Document 2, the user cannot accurately judge the situation, such as whether or not evacuation is truly necessary.

Patent Document 3 describes a disaster information distribution system that automatically distributes emails for disclosing disaster information when a disaster that may cause damage to spread occurs or when there is a risk of such an occurrence in an emergency. In the technology described in Patent Document 3, the disaster information distribution system has an information management server that includes a disaster information extraction means for extracting disaster information data, a disclosure information processing means for processing the extracted disaster information so that it can be disclosed, an email creation means for creating predetermined email data for email based on the disaster information data processed so that it can be disclosed, and a web control means for transmitting the created email data to a web server and controlling the sending of the email to a predetermined address.
However, in the technology described in Patent Document 3, disaster information is distributed only to members. In addition, the disaster information distributed in the technology described in Patent Document 3 does not encourage residents to evacuate. Therefore, even with the technology described in Patent Document 3, users cannot accurately judge the situation, such as whether or not evacuation is truly necessary.

Patent Literature 4 describes a disaster prevention system that performs disaster countermeasure operations when it receives disaster advance information that predicts the occurrence of a natural disaster in advance. In the technology described in Patent Literature 4, it is determined whether or not residents need to evacuate based on the disaster advance information and house information, and when it is determined that evacuation is necessary, evacuation instruction information is notified.
In the technology described in Patent Document 4, the possibility of a landslide is judged independently for each building based on a rainfall threshold determined independently for each building and the amount of rainfall received by a wide area network communication means. Also, when it is judged that a landslide is likely to occur, an evacuation instruction is output to the residents of the building.
In other words, in the technology described in Patent Document 4, whether or not there is a possibility of a landslide occurring is determined independently for each building, rather than being determined based on meteorological disaster information such as landslide warning information and landslide warning determination mesh information indicating areas to be warned. Therefore, even with the technology described in Patent Document 4, the user cannot accurately determine the situation, such as whether or not evacuation is truly necessary.

Below, embodiments of the information providing server, information providing system, information providing method, and program of the present invention will be described with reference to the attached drawings.

First Embodiment
FIG. 1 is a diagram showing an example of an information providing server 1 according to the first embodiment.
In the example shown in Figure 1, the information providing server 1 includes, for example, a meteorological disaster information acquisition unit 11, a user information storage unit 12, a first judgment unit 13, a content generation unit 14, a content distribution unit 15, and a disaster response unit 18.
In the example shown in FIG. 1, the information providing server 1 includes a disaster response unit 18, but in other examples, the information providing server 1 does not need to include the disaster response unit 18.

1, the meteorological disaster information acquisition unit 11 acquires meteorological disaster information, which is information indicating areas under alert for weather or disasters, from outside the information providing server 1. The meteorological disaster information includes data on, for example, landslide warning information issued by the Japan Meteorological Agency, landslide warning determination mesh information, meteorological warnings, typhoon information, earthquake information, and risk distribution information for heavy rain warnings (flooding).
The areas under alert are composed of multiple mesh regions, such as areas under alert for landslide warning mesh information published by the Japan Meteorological Agency, and areas under alert for information on the distribution of risk levels for heavy rain warnings (flooding) (areas where risk levels of yellow, red, light purple, or dark purple appear).
For example, just as the landslide warning mesh information and heavy rain warning (flooding) risk distribution information published by the Japan Meteorological Agency are information indicating the risk level of each mesh area, the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 is information indicating the risk level of each mesh area.

In the example shown in Fig. 1, the user information storage unit 12 stores user information including address information or location information of a user's home. The location information is, for example, information (coordinate information) such as latitude and longitude. The point indicating the latitude and longitude may be any point on the site of the user's home, such as the center point of the site, a point on the periphery of the site, the center of gravity of the site, or the intersection of diagonals of a rectangular site.
1, the administrator of the information providing server 1 is a company that has undertaken the construction of a user's home. The user information storage unit 12 stores user information including address information or location information of a plurality of user's homes that have been undertaken by the administrator of the information providing server 1. In another example, the administrator of the information providing server 1 does not need to be the company that has undertaken the construction of a user's home.

In the example shown in FIG. 1 , the user information stored in the user information storage unit 12 includes, for example, information (first information) obtained by an investigation of the construction site and its surroundings before construction work on the user's house begins. The first information includes, for example, the elevation difference of the site and its surroundings, the angle of the slope, etc. The first information also includes the geology, groundwater level, ground strength, etc. The first information also includes the condition of structures such as retaining walls and earth retaining structures. The first information also includes the condition and depth of gutters, waterways, etc.
The user information stored in the user information storage unit 12 also includes information (second information) on the building, site, attached structures, etc., at the time of completion of construction work on the user's house. The second information includes information on the shape, form (number of floors, presence or absence of a roof, etc.), layout, foundation specifications, etc. of the building. The second information also includes the elevation difference between the site and the surrounding area. The second information also includes information on newly constructed retaining walls, retaining walls, fences, etc.
The user information stored in the user information storage unit 12 also includes, for example, information on the user's home after delivery (third information). The third information includes, for example, information on building renovations. The third information also includes information on damage conditions and recovery from past disasters.
The user information stored in the user information storage unit 12 also includes, for example, information (fourth information) about a resident of the user's home. The fourth information includes, for example, the gender, age, place of employment, place of school or kindergarten, health condition (degree of health), and room in which the user (resident of the user's home) sleeps.
The user information stored in the user information storage unit 12 can be used to predict damage and prioritize relief efforts, for example, when a user's home is affected by a disaster.

1 , the first determination unit 13 determines whether or not a user's home is included in a warning area based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 and the user information stored in the user information storage unit 12. In detail, the first determination unit 13 determines whether or not the user's home is included in any of a plurality of mesh areas constituting the warning area indicated by the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11.
In another example, the first determination unit 13 may determine whether or not a user's home is included in the alert area based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 and user information, for example, directly input to the information providing server 1.

1 , when the first determination unit 13 determines that the user's home is included in the alert area, the content generation unit 14 generates alert content based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11. In detail, when the user's home is included in any of a plurality of mesh areas constituting the alert area indicated by the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11, the content generation unit 14 generates alert content indicating the degree of danger of the mesh area including the user's home.
The content generating unit 14 includes a customization unit 14A. The customization unit 14A customizes a map on which a plurality of mesh regions are displayed, for example, in landslide warning mesh information published by the Japan Meteorological Agency, heavy rain warning (flooding) risk distribution information, and the like.
The content distribution unit 15 distributes the alert content generated by the content generation unit 14. In detail, the content distribution unit 15 distributes the alert content to terminal devices used by users (e.g., each of all residents of a user's home).

1, the disaster response unit 18 judges the severity of damage to a user's home when the user's home is damaged. The disaster response unit 18 includes a damage severity calculation unit 18A, a landslide risk information collection unit 18B, a damaged home extraction unit 18C, a damage map generation unit 18D, and a response schedule development unit 18E.
When a user's home is damaged, the damage severity calculation unit 18A calculates the damage severity, which is the product of the disaster risk and time, for each user's home. For example, "extremely dangerous" out of the five levels of landslide warning determination mesh information and information on the risk distribution of heavy rain warning (flooding) announced by the Japan Meteorological Agency corresponds to "disaster risk level 10". "Very dangerous" out of the five levels of landslide warning determination mesh information and information on the risk distribution of heavy rain warning (flooding) corresponds to "disaster risk level 7". "Caution" out of the five levels of landslide warning determination mesh information and information on the risk distribution of heavy rain warning (flooding) corresponds to "disaster risk level 3". "Caution" out of the five levels of landslide warning determination mesh information and information on the risk distribution of heavy rain warning (flooding) corresponds to "disaster risk level 1". "Pay attention to future information, etc." out of the five levels of landslide warning determination mesh information and information on the risk distribution of heavy rain warning (flooding) corresponds to "disaster risk level 0".
In another example, instead of the above-mentioned disaster risk level, for example, the maximum disaster risk level reached by the user's home may be used.

In the example shown in Figure 1, the landslide disaster risk information collection unit 18B collects nationwide landslide disaster risk information, information on the risk distribution of heavy rain warnings (flooding), and the like as list data at regular intervals from the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11.
The damaged home extraction unit 18C refers to the user information stored in the user information storage unit 12 and converts and stores, for each user home, landslide risk information collected by the landslide risk information collection unit 18B, information on the risk distribution of heavy rain warnings (flooding), etc.
The damage map generating unit 18D generates a list of damaged user homes (damaged user home list) and a damage map (a map showing the positions, density, etc. of damaged user homes) based on the information accumulated by the damaged home extracting unit 18C. The damaged user home list is generated by sorting the damage severity calculated for each user home by the damage severity calculating unit 18A in descending order of damage severity.
The response schedule formulation unit 18E formulates a response schedule in descending order of the severity of damage based on the list of disaster-affected users' homes generated by the damage severity map generation unit 18D.
The administrator of the information providing server 1 (the company that contracted to build the user's home) provides support to the affected user's home based on the response schedule formulated by the response schedule formulation unit 18E.

In detail, the administrator of the information providing server 1 (the company that has contracted to build the user's home) calls the user's home in an area that has been damaged by a typhoon or flood to hear about the damage situation. The administrator of the information providing server 1 also checks whether there has been a service call from the user's home and the content of the call. The administrator of the information providing server 1 also takes into consideration official disaster level information (issuance of warnings and advisories, evacuation orders, infrastructure shutdown information, etc.) and performs on-site inspections, identification and estimates of necessary repairs, judgment on insurance coverage, repair work, etc.
In the example shown in Figure 1, the criteria used to determine whether to do these things include "how much risk of landslides has the user's home reached?" and "how much risk of flooding has the user's home reached?"
On a website operated by the administrator of the information providing server 1, information is provided based on the list of disaster-affected user homes, and priority is given to inquiries (calls) from users with high disaster severity. For users with low disaster severity, FAQs (Frequently Asked Questions) are provided.

FIG. 2 is a diagram showing an example of an information providing system X according to the first embodiment.
In the example shown in Figure 2, the information provision system X includes a meteorological disaster information announcement unit A1 that announces meteorological disaster information, which is information indicating areas under alert for weather or disasters, a meteorological disaster information data distribution unit A2 that distributes the meteorological disaster information announced by the meteorological disaster information announcement unit A1, the information provision server 1 shown in Figure 1, and a terminal device B1.
A meteorological disaster information announcement unit A1, such as the Japan Meteorological Agency, announces meteorological disaster information such as landslide warning information, landslide warning judgment mesh information, weather warnings, typhoon information, earthquake information, and information on the risk distribution of heavy rain warnings (flooding).
A meteorological disaster information data distribution unit A2, such as a meteorological data providing service company, distributes the meteorological disaster information data announced by the meteorological disaster information announcement unit A1 in a usable (processable) format.
The meteorological disaster information acquisition unit 11 (see FIG. 1 ) of the information providing server 1 acquires meteorological disaster information data (such as landslide warning mesh information, heavy rain warning (flooding) risk distribution information, etc.) distributed by the meteorological disaster information data distribution unit A2. For example, in the landslide warning mesh information and heavy rain warning (flooding) risk distribution information, alert areas (areas with increasing risk) are displayed on a map using multiple mesh areas.

FIG. 3 is a diagram showing an example of a plurality of mesh areas displayed on a map as areas to be alerted in the landslide disaster alert determination mesh information.
In the example shown in Fig. 3(A), six mesh areas, which are areas subject to warning and have a risk of landslides due to heavy rainfall of "very dangerous," are displayed on a map of landslide warning mesh information. The mesh area at the far right and bottom of Fig. 3(A), which is "very dangerous," includes the homes of users of the information providing server 1.

In the examples shown in Figures 2 and 3(A), the first determination unit 13 (see Figure 1) of the information providing server 1 determines that the user's house is included in a warning area (one of the six mesh areas shown in Figure 3(A)) in the landslide warning determination mesh information. In detail, the first determination unit 13 determines that the user's house is included in a mesh area that corresponds to "high danger."
Therefore, the content generation unit 14 (see Figure 1) of the information providing server 1 generates alert content based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 (more specifically, based on information that the mesh area including the user's home is a mesh area that corresponds to "very dangerous").

In other words, in the example shown in Figures 2 and 3 (A), when the danger level of the mesh area including the user's home reaches a predetermined danger level, the first judgment unit 13 judges that the user's home is included in the alert area, the content generation unit 14 generates alert content, and the content distribution unit 15 distributes the alert content.
In another example, when the risk level of a mesh area including a user's home, reflecting a weighting over time, reaches a predetermined value, the first judgment unit 13 judges that the user's home is included in the area under surveillance, the content generation unit 14 generates alert content, and the content distribution unit 15 distributes the alert content.
In yet another example, when a predetermined time has elapsed since the risk level of the mesh area including the user's home, reflecting a time-dependent weighting, reaches a predetermined value, the first judgment unit 13 may judge that the user's home is included in the area under surveillance, the content generation unit 14 may generate alert content, and the content distribution unit 15 may distribute the alert content.

FIG. 4 is a diagram for explaining an example in which the content generating unit 14 of the information providing server 1 according to the first embodiment generates an alert content.
In the example shown in Figure 4 (A), the content generation unit 14 of the information providing server 1 generates an email as alert content indicating the level of danger ("very dangerous") of a mesh area (the rightmost and lower mesh area of the six mesh areas corresponding to "very dangerous" in Figure 3 (A)) including the user's home (see Figure 3 (A)) and the level of danger of mesh areas located around the mesh area including the user's home (surrounding mesh areas).
The content distribution section 15 (see FIG. 1) of the information providing server 1 transmits the e-mail generated by the content generation section 14 to the terminal device B1 used by the user.
4, the terminal device B1 used by the user is a terminal device carried by the user, such as a smartphone. In another example, the terminal device B1 may be a portable terminal device other than a smartphone.

In the example shown in Fig. 4(A), an e-mail generated by the content generating unit 14 and sent to the user's terminal device B1 by the content distributing unit 15 states that the user's home is included in a mesh area in which the increased risk level in the landslide warning determination mesh information corresponds to "very dangerous." The e-mail also states a uniform resource locator (URL) that enables the user to view a custom map, which will be described later. The user can understand the distribution of the custom map by looking at the URL for viewing the custom map stated in the e-mail.
As described above, the customization unit 14A of the content generation unit 14 of the information providing server 1 customizes a map on which a plurality of mesh regions are displayed in, for example, landslide warning mesh information published by the Japan Meteorological Agency, heavy rain warning (flooding) risk distribution information, etc. In the example shown in Figures 3(A) and 3(B), the customization unit 14A customizes the map shown in Figure 3(A) to generate the custom map shown in Figure 3(B).
As shown in Figures 3(A) and 3(B), in the custom map shown in Figure 3(B), the user's house in the map shown in Figure 3(A) is moved to the center position of the custom map shown in Figure 3(B). In another example, in the custom map, the user's house may be moved to a position other than the center position of the custom map. In this example, the user's house is also moved to a position other than the periphery of the custom map, and eight mesh areas (surrounding mesh areas) located around the mesh area including the user's house are also included in the custom map. In other words, the map shown in Figure 3(A) may be used as the custom map as is.
In the example shown in FIG. 4B, the content distribution unit 15 distributes a custom map (see FIG. 3B) that is generated by the customization unit 14A and can be displayed by the terminal device B1.

As described above, in the examples shown in Figures 1 to 4, the user can grasp that the danger level of the mesh area including the user's house corresponds to "very dangerous" and that the danger levels of the three surrounding mesh areas correspond to "very dangerous". As a result, the user can accurately judge the situation, such as whether or not evacuation is truly necessary, and if evacuation is necessary, whether it is appropriate to evacuate toward the lower right in Figure 3. In detail, the user can judge the situation in real time, without being delayed by announcements from the Japan Meteorological Agency, for example.
Furthermore, in the example shown in Figures 1 to 4, as shown in Figures 3 (B) and 4 (B), the user can understand that the risk level of the mesh area (an area smaller than a city, ward, town, or village) including the user's home corresponds to "very dangerous", rather than the risk level of the city, ward, town, or village including the user's home, and that the risk levels of the three surrounding mesh areas correspond to "very dangerous".
Furthermore, in the examples shown in Figures 1 to 4, as shown in Figures 4(A) and 4(B), the user can understand by email that the risk level of the mesh area including the user's home is equivalent to "very dangerous" and that the risk level of the surrounding mesh areas is equivalent to "very dangerous" without having to browse a homepage showing meteorological disaster information, such as landslide warning mesh information published by the Japan Meteorological Agency.
Furthermore, in the example shown in Figures 1 to 4, as shown in Figures 3 (B) and 4 (B), the user can visually understand from the custom map that the danger level of the mesh area including the user's home corresponds to "very dangerous," and that the danger levels of the three surrounding mesh areas correspond to "very dangerous."
In the example shown in FIG. 1 to FIG. 4, as shown in FIG. 4(A) and FIG. 4(B), alert content indicating that the danger level of the mesh area including the user's house corresponds to "very dangerous" and that the danger level of the surrounding mesh areas corresponds to "very dangerous" is delivered to the terminal device B1 carried by the user. Therefore, even when the user is outside the user's house, the user can understand that the danger level of the mesh area including the user's house corresponds to "very dangerous" and that the danger level of the surrounding mesh areas corresponds to "very dangerous". As a result, a user outside the user's house can inform a user in the user's house of the danger at the user's house and encourage the user to take measures such as evacuation. In addition, a user outside the user's house can determine whether or not to avoid returning to the user's house from outside the user's house.
1 to 4, as described above, the administrator of the information providing server 1 is the company that contracted the construction of the user's house. Therefore, the information providing server 1 can appropriately provide the user with information such as the risk level of the mesh area including the user's house by utilizing the user information obtained at the time of construction of the user's house.

1 to 4, as described above, the address information or location information of the user's home is provided by the administrator of the information providing server 1 (the company that undertook the construction contract for the user's home) and stored in the user information storage unit 12, but in other examples, the address information or location information of the user's home may be acquired by a device installed in the user's home and stored in the user information storage unit 12. In this example, the address information or location information of the user's home is acquired by using, for example, a Global Positioning System (GPS), Internet location information, LTE (Long Term Evolution) connection base station information, or the like.
1 to 4, the information providing server 1 is located outside the user's home. More specifically, the information providing server 1 is located in an area other than the Kanto region. In other examples, a part or the whole of the information providing server 1 may be located on the cloud.
1 to 4, the information providing server 1 is equipped with an emergency power supply and a seismic isolation device. The components of the information providing server 1 are arranged in the same data center and within the same firewall. This can improve the crisis management and backup system of the information providing server 1.

FIG. 5 is a flowchart for explaining an example of a process executed in the information providing server 1 of the first embodiment.
In the example shown in FIG. 5, in step S1, the meteorological disaster information acquisition unit 11 acquires meteorological disaster information, which is information indicating areas under alert for weather or disasters.
In addition, in step S2, the user information storage unit 12 stores user information including address information or location information of the user's home, which is the user's residence.
Next, in step S3, the first determination unit 13 determines whether or not the user's home is included in the alert area based on the meteorological disaster information acquired in step S1 and the user information stored in step S2. In detail, in step S3, the first determination unit 13 determines whether or not the user's home is included in any of the multiple mesh areas that make up the alert area.
If it is determined in step S3 that the user's home is included in the alert area, then in step S4, the content generator 14 generates alert content based on the meteorological disaster information acquired in step S1. In detail, if it is determined in step S3 that the user's home is included in any of the mesh areas, then in step S4, the content generator 14 generates alert content indicating the risk level of the mesh area including the user's home and the risk level of the surrounding mesh areas that are mesh areas located around the mesh area including the user's home.
Next, in step S5, the content delivery unit 15 delivers the alert content generated in step S4. In detail, in step S5, the content delivery unit 15 delivers the alert content to the terminal device B1 used by the user.

FIG. 6 is a diagram showing another example of the information providing system X according to the first embodiment.
In the example shown in FIG. 6(A), an information providing system X includes a meteorological and disaster information announcement section A1, a meteorological and disaster information data distribution section A2, the information providing server 1 shown in FIG. 1, and a terminal device B2.
In the example shown in Fig. 6(A), similarly to the example shown in Fig. 2, the meteorological disaster information announcement unit A1 announces meteorological disaster information such as landslide warning information, landslide warning judgment mesh information, weather warnings, typhoon information, earthquake information, heavy rain warning (flooding) risk distribution information, etc. The meteorological disaster information data distribution unit A2 distributes the data of the meteorological disaster information announced by the meteorological disaster information announcement unit A1 in a usable (processable) format.
The meteorological disaster information acquisition unit 11 (see Figure 1) of the information providing server 1 acquires meteorological disaster information data distributed by the meteorological disaster information data distribution unit A2 (e.g., data such as landslide warning determination mesh information, risk distribution information for heavy rain warnings (flooding), etc.).
The first determination unit 13 (see Figure 1) of the information providing server 1 determines whether the user's house is included in a warning area (for example, any of the six mesh areas corresponding to "very dangerous" as shown in Figure 3 (A)) in landslide warning determination mesh information, heavy rain warning (flooding) risk distribution information, etc.
When the user's home is included in the alert area, the content generation unit 14 (see FIG. 1 ) of the information providing server 1 generates alert content based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 .

In the example shown in Figure 6 (B), the content generation unit 14 of the information providing server 1 generates an email as alert content, for example, stating that the danger level of the mesh area including the user's home is "very dangerous" and that the danger level of the surrounding mesh areas is equivalent to "very dangerous."
The content distribution section 15 (see FIG. 1) of the information providing server 1 transmits the e-mail generated by the content generation section 14 to the terminal device B2 used by the user.
6, the terminal device B2 used by the user is a terminal device located in the user's home, such as a personal computer. In another example, the terminal device B2 may be a terminal device other than a personal computer (such as a television or other device that can connect to the Internet).

In the example shown in FIG. 6B, the email sent by the content delivery unit 15 to the user's terminal device B2 includes a URL that enables the user to view the custom map.
In the example shown in FIG. 6C, the content distribution unit 15 distributes a custom map (see FIG. 3B, for example) that is generated by the customization unit 14A and can be displayed by the terminal device B2.

In the examples shown in Figs. 6(B) and 6(C), unlike the examples shown in Figs. 4(A) and 4(B), alert content is delivered to terminal device B2 located in the user's home. Therefore, in the example shown in Fig. 6, the user in the user's home can understand that the danger level of the mesh area including the user's home is "very dangerous" and that the danger level of the surrounding mesh areas is equivalent to "very dangerous."

FIG. 7 is a diagram showing another example of the information providing server 1 according to the first embodiment.
In the example shown in Figure 7, the information providing server 1 includes, for example, a meteorological disaster information acquisition unit 11, a user information storage unit 12, a first judgment unit 13, a content generation unit 14, a content distribution unit 15, a second judgment unit 16, a judgment result transmission unit 17, and a disaster response unit 18.
In the example shown in FIG. 7, the information providing server 1 includes a disaster response unit 18, but in other examples, the information providing server 1 does not need to include the disaster response unit 18.

In the example shown in Figure 7, the second judgment unit 16 judges whether a user in the user's home should evacuate outside the user's home or whether a user in the user's home should remain in the user's home based on the user information stored in the user information storage unit 12, the risk level of the mesh area including the user's home, and the risk level of the surrounding mesh area, which is a mesh area located around the mesh area including the user's home.
The judgment result transmission unit 17 transmits the judgment result by the second judgment unit 16 as to whether a user in the user's home should evacuate outside the user's home or whether a user in the user's home should remain in the user's home to the terminal device B1 used by the user.

FIG. 8 is a diagram for explaining a mesh area MU including a user's house, and surrounding mesh areas MS1 to MS8 positioned around the mesh area MU including the user's house.
In the example shown in Fig. 8(A), six mesh areas M1, M2, MS1, MS2, MS4, and MU, which are areas under warning and have a risk of landslides due to heavy rainfall of "very high risk," are displayed on a map of landslide warning mesh information. Mesh area MU includes the homes of users of the information providing server 1.
Of the surrounding mesh areas MS1 to MS8 located around the mesh area MU including the user's house, the surrounding mesh area MS1 located on the northwest side of the mesh area MU, the surrounding mesh area MS2 located on the north side of the mesh area MU, and the surrounding mesh area MS4 located on the west side of the mesh area MU correspond to a risk level of "very dangerous."
Of the surrounding mesh areas MS1 to MS8, the surrounding mesh area MS3 located on the northeast side of mesh area MU, the surrounding mesh area MS5 located on the east side of mesh area MU, the surrounding mesh area MS6 located on the southwest side of mesh area MU, the surrounding mesh area MS7 located on the south side of mesh area MU, and the surrounding mesh area MS8 located on the southeast side of mesh area MU correspond to a risk level of "pay attention to future information, etc.".
In the example shown in Figures 7 and 8 (A), the second judgment unit 16 judges that the user in the user's home should evacuate to surrounding mesh area MS8, which is a surrounding mesh area having a danger level equivalent to "pay attention to future information, etc." and is away from mesh areas M1, M2, MS1, MS2, and MS4 having a danger level equivalent to "very dangerous."

FIG. 9 is a diagram showing an application example of the information providing server 1 of the first embodiment shown in FIG.
In the example shown in Fig. 9, similarly to the example shown in Fig. 2, the meteorological disaster information announcement unit A1 announces meteorological disaster information such as landslide warning information, landslide warning judgment mesh information, weather warnings, typhoon information, earthquake information, heavy rain warning (flooding) risk distribution information, etc. The meteorological disaster information data distribution unit A2 distributes the data of the meteorological disaster information announced by the meteorological disaster information announcement unit A1 in a usable (processable) format.
The meteorological disaster information acquisition unit 11 (see Figure 7) of the information providing server 1 acquires meteorological disaster information data distributed by the meteorological disaster information data distribution unit A2 (e.g., data such as landslide warning determination mesh information, information on the risk distribution of heavy rain warnings (flooding), etc.).
The first judgment unit 13 (see Figure 7) of the information providing server 1 judges whether the user's house is included in a warning area (for example, any of the six mesh areas M1, M2, MS1, MS2, MS4, MU shown in Figure 8 (A)) in landslide warning judgment mesh information, heavy rain warning (flooding) risk distribution information, etc.
When the user's home is included in the alert area, the content generation unit 14 (see FIG. 7) of the information providing server 1 generates alert content based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 .

In the example shown in FIG. 9A, the content generating unit 14 of the information providing server 1 generates an e-mail as alert content, which indicates, for example, a danger level of "very dangerous" for the mesh area MU including the user's house, a danger level of "very dangerous" for the surrounding mesh area MS1 located on the northwest side of the mesh area MU, a danger level of "very dangerous" for the surrounding mesh area MS2 located on the north side of the mesh area MU, a danger level of "pay attention to future information, etc." for the surrounding mesh area MS3 located on the northeast side of the mesh area MU, a danger level of "very dangerous" for the surrounding mesh area MS4 located on the west side of the mesh area MU, a danger level of "pay attention to future information, etc." for the surrounding mesh area MS5 located on the east side of the mesh area MU, a danger level of "pay attention to future information, etc." for the surrounding mesh area MS6 located on the southwest side of the mesh area MU, a danger level of "pay attention to future information, etc." for the surrounding mesh area MS7 located on the south side of the mesh area MU, and a danger level of "pay attention to future information, etc." for the surrounding mesh area MS8 located on the southeast side of the mesh area MU.
The content distribution section 15 (see FIG. 7) of the information providing server 1 transmits the e-mail generated by the content generation section 14 to the terminal device B1 used by the user.
9, the terminal device B1 used by the user is a terminal device carried by the user, such as a smartphone. In another example, the terminal device B1 may be a portable terminal device other than a smartphone.

In the example shown in Fig. 9(A), a URL for the user to view the custom map shown in Fig. 8(B) is included in the email that is generated by content generation unit 14 and sent to the user's terminal device B1 by content distribution unit 15. The user can understand that the custom map has been distributed by looking at the URL for viewing the custom map included in the email.
In the examples shown in Figures 8(A) and 8(B), the customization unit 14A (see Figure 7) performs customization of the map shown in Figure 8(A) to generate the custom map shown in Figure 8(B).
As shown in Figures 8(A) and 8(B), in the custom map shown in Figure 8(B), the user's house in the map shown in Figure 8(A) has been moved to a position other than the periphery of the custom map shown in Figure 8(B) (more specifically, to the central position).
In the example shown in FIG. 9B, the content distribution unit 15 distributes a customized map (see FIG. 8B) that is generated by the customization unit 14A and can be displayed by the terminal device B1.

As described above, in the examples shown in Figures 7 to 9, the content generation unit 14 generates an e-mail indicating a danger level of "very dangerous" for the mesh area MU including the user's home, a danger level of "very dangerous" for the surrounding mesh areas MS1, MS2, and MS4 located around the mesh area MU including the user's home, and a danger level of "pay attention to future information, etc." for the surrounding mesh areas MS3, MS5, MS6, MS7, and MS8.
Therefore, in the examples shown in Figures 7 to 9, by understanding not only the danger level of the mesh area MU that includes the user's home, which is "very dangerous," but also the danger level of the surrounding mesh areas MS1, MS2, and MS4, which is "very dangerous," and the danger level of the surrounding mesh areas MS3, MS5, MS6, MS7, and MS8, which is "pay attention to future information, etc.", the user can consider a more appropriate evacuation route from the user's home than if he or she did not understand the danger level of the surrounding mesh areas MS1, MS2, and MS4, which is "very dangerous," and the danger level of the surrounding mesh areas MS3, MS5, MS6, MS7, and MS8, which is "pay attention to future information, etc."

In the examples shown in Figures 7 to 9, the custom map shown in Figure 8(B) includes a risk level of "very dangerous" for the mesh area MU that includes the user's house, a risk level of "very dangerous" for the surrounding mesh areas MS1, MS2, and MS4, and a risk level of "pay attention to future information, etc." for the surrounding mesh areas MS3, MS5, MS6, MS7, and MS8. In addition, the custom map shown in Figure 8(B) is distributed by the content distribution unit 15 and displayed by the user's terminal device B1.
Therefore, in the example shown in Figures 7 to 9, the user can visually grasp, by using the custom map shown in Figure 8 (B), the danger level of the mesh area MU that includes the user's house, which is "very dangerous," the danger level of the surrounding mesh areas MS1, MS2, and MS4, which is "very dangerous," and the danger level of the surrounding mesh areas MS3, MS5, MS6, MS7, and MS8, which is "pay attention to future information, etc."

In the examples shown in Figures 7 to 9, as described above, the judgment result by the second judgment unit 16 as to whether a user in the user's home should evacuate outside the user's home or whether a user in the user's home should remain in the user's home is transmitted to the user's terminal device B1 by the judgment result transmission unit 17.
Therefore, in the examples shown in Figures 7 to 9, the user can use the judgment result transmitted by the judgment result transmission unit 17 as a basis for deciding whether to evacuate outside the user's home or to remain in the user's home.

FIG. 10 is a diagram showing an example of the information providing system X of the first embodiment including the information providing server 1 shown in FIG.
In the example shown in FIG. 10(A), an information providing system X includes a meteorological disaster information announcement section A1, a meteorological disaster information data distribution section A2, the information providing server 1 shown in FIG. 7, and a terminal device B2.
The meteorological disaster information announcement unit A1 announces meteorological disaster information such as landslide warning information, landslide warning judgment mesh information, weather warnings, typhoon information, earthquake information, heavy rain warning (flooding) risk distribution information, etc. The meteorological disaster information data distribution unit A2 distributes the data of the meteorological disaster information announced by the meteorological disaster information announcement unit A1 in a usable (processable) format.
The meteorological disaster information acquisition unit 11 (see Figure 7) of the information providing server 1 acquires meteorological disaster information data distributed by the meteorological disaster information data distribution unit A2 (e.g., data such as landslide warning determination mesh information, information on the risk distribution of heavy rain warnings (flooding), etc.).
The first judgment unit 13 (see Figure 7) of the information providing server 1 judges whether the user's house is included in a warning area (for example, any of the six mesh areas M1, M2, MS1, MS2, MS4, MU shown in Figure 8 (A)) in landslide warning judgment mesh information, heavy rain warning (flooding) risk distribution information, etc.
When the user's home is included in the alert area, the content generation unit 14 (see FIG. 2) of the information providing server 1 generates alert content based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11 .

In the example shown in Figure 10 (B), the content generation unit 14 of the information providing server 1 generates an email as alert content, which includes, for example, a danger level of "very dangerous" for mesh area MU including the user's home, a danger level of "very dangerous" for surrounding mesh areas MS1, MS2, and MS4, and a danger level of "pay attention to future information, etc." for surrounding mesh areas MS3, MS5, MS6, MS7, and MS8.
The content distribution section 15 (see FIG. 7) of the information providing server 1 transmits the e-mail generated by the content generation section 14 to the terminal device B2 used by the user.
10, the terminal device B2 used by the user is a terminal device located in the user's home, such as a personal computer. In another example, the terminal device B2 may be a terminal device other than a personal computer (such as a television or other device that can connect to the Internet).

In the example shown in FIG. 10B, the email sent by the content distribution unit 15 to the user's terminal device B2 includes a URL that enables the user to view the custom map.
In the example shown in FIG. 10C, the content distribution unit 15 distributes a custom map (see FIG. 8B, for example) that is generated by the customization unit 14A and can be displayed by the terminal device B2.

In the example shown in FIG. 10, the determination result transmission unit 17 (see FIG. 7) of the information providing server 1 transmits to the user's terminal device B2 the determination result by the second determination unit 16 (see FIG. 7) as to whether the user in the user's home should evacuate outside the user's home or whether the user in the user's home should remain in the user's home.

In the above-described example, the customization unit 14A customizes a map that displays multiple mesh areas such as landslide warning mesh information published by the Japan Meteorological Agency and information on the distribution of risk of heavy rain warnings (flooding).
In another example, the customization unit 14A may customize a map in which multiple mesh areas are displayed for information other than landslide warning mesh information and heavy rain warning (flooding) risk distribution information (e.g., information indicating areas under alert for earthquakes), such as the risk distribution of flood warnings issued by the Japan Meteorological Agency.

Second Embodiment
An information providing server, an information providing system, an information providing method, and a program according to a second embodiment of the present invention will be described below.
The information providing server 1 of the second embodiment is configured similarly to the information providing server 1 of the first embodiment described above, except for the points described below. Therefore, the information providing server 1 of the second embodiment can achieve the same effects as the information providing server 1 of the first embodiment described above, except for the points described below.

The information providing server 1 of the second embodiment is configured similarly to the information providing server 1 of the first embodiment shown in FIG.
In one example of the information provision system X of the second embodiment, a meteorological disaster information announcement unit A1 (see FIG. 2) announces meteorological disaster information such as landslide warning information, landslide warning judgment mesh information, weather warnings, typhoon information, earthquake information, heavy rain warning (flooding) risk distribution information, etc. A meteorological disaster information data distribution unit A2 (see FIG. 2) distributes the data of the meteorological disaster information announced by the meteorological disaster information announcement unit A1 in a usable (processable) format.
The meteorological disaster information acquisition unit 11 (see Figure 1) of the information providing server 1 acquires meteorological disaster information data distributed by the meteorological disaster information data distribution unit A2 (e.g., landslide warning determination mesh information, information on the risk distribution of heavy rain warnings (flooding), earthquake information, etc.).

In one example of the information providing server 1 of the second embodiment, the first determination unit 13 (see Figure 1) of the information providing server 1 determines whether or not the user's house is included in a warning area (for example, any of the six mesh areas shown in Figure 3 (A)) in landslide warning determination mesh information, information on the distribution of risk of heavy rain warnings (flooding), earthquake information, etc.
The content generating unit 14 (see FIG. 1) of the information providing server 1 generates alert content based on meteorological disaster information acquired by the meteorological disaster information acquiring unit 11 when the first determining unit 13 determines that the user's home is included in a warning area. The content generating unit 14 includes a customizing unit 14A (see FIG. 1). The customizing unit 14A customizes a map on which multiple mesh regions are displayed in, for example, landslide warning determination mesh information, heavy rain warning (flooding) risk distribution information, earthquake information, and the like announced by the Japan Meteorological Agency, and generates a custom map (see FIG. 3B).
The content distribution unit 15 (see FIG. 1) of the information providing server 1 distributes customized maps and the like as alert content generated by the content generation unit 14.

FIG. 11 is a diagram for explaining an example in which the content generating unit 14 of the information providing server 1 according to the second embodiment generates an alert content.
11(A), when the first determination unit 13 determines that the user's home is included in a warning area in the landslide warning determination mesh information, the heavy rain warning (flooding) risk distribution information, earthquake information, etc., the content distribution unit 15 of the information providing server 1 transmits a push notification to the terminal device (smartphone) B1 carried by the user. The push notification transmitted by the content distribution unit 15 is a notification that prompts the user to display a custom map (see FIG. 3(B)) in a dedicated application on the terminal device (smartphone) B1.
In the example shown in FIG. 11(B), the content distribution unit 15 distributes a customized map that is generated by the customization unit 14A and displayed by the terminal device (smartphone) B1.

As described above, in one example of the information providing server 1 of the second embodiment, a push notification prompting the user to display a custom map is sent from the information providing server 1 to the terminal device (smartphone) B1 carried by the user. This makes it possible to reduce the risk that the user will not perform the display operation of the custom map, compared to when the push notification is not sent.

In another example of the information providing server 1 of the second embodiment, the information providing server 1 is configured similarly to the information providing server 1 shown in Fig. 7. In this example, the second determination unit 16 determines whether a user in the user's home should evacuate outside the user's home or whether the user in the user's home should remain in the user's home, based on the user information stored in the user information storage unit 12, the risk level of the mesh area including the user's home, and the risk level of the surrounding mesh areas that are mesh areas surrounding the mesh area including the user's home.
In addition, in this example, the judgment result transmission unit 17 transmits the judgment result by the second judgment unit 16 as to whether a user in the user's home should evacuate outside the user's home or whether the user in the user's home should remain in the user's home to the terminal device (smartphone) B1 used by the user.

In yet another example of the information providing server 1 of the second embodiment, the first determination unit 13 (see Figure 7) of the information providing server 1 determines whether or not the user's house is included in a warning area (for example, any of the six mesh areas M1, M2, MS1, MS2, MS4, MU shown in Figure 8 (A)) in landslide warning determination mesh information, information on the distribution of risk of heavy rain warnings (flooding), earthquake information, etc.
The content generating unit 14 (see FIG. 7) of the information providing server 1 generates alert content based on meteorological disaster information acquired by the meteorological disaster information acquiring unit 11 when the first determining unit 13 determines that the user's home is included in the alert area. The content generating unit 14 includes a customizing unit 14A (see FIG. 7). The customizing unit 14A customizes a map (see FIG. 8A) on which multiple mesh areas are displayed in landslide alert determination mesh information, heavy rain warning (flooding) risk distribution information, earthquake information, and the like, which are announced by the Japan Meteorological Agency, and generates a custom map (see FIG. 8B).

Third Embodiment
An information providing server, an information providing system, an information providing method, and a program according to a third embodiment of the present invention will be described below.
The information providing server 1 of the third embodiment is configured similarly to the information providing server 1 of the first embodiment described above, except for the points described below. Therefore, the information providing server 1 of the third embodiment can achieve the same effects as the information providing server 1 of the first embodiment described above, except for the points described below.

The information providing server 1 of the third embodiment has almost the same configuration as the information providing server 1 of the first embodiment shown in FIG.
FIG. 12 is a diagram showing an example of an information providing system X according to the third embodiment.
In the example shown in FIG. 12, an information providing system X includes a meteorological and disaster information announcement section A1, a meteorological and disaster information data distribution section A2, the information providing server 1 shown in FIG. 1, and a terminal device B3.
The meteorological disaster information announcement unit A1 announces meteorological disaster information such as landslide warning information, landslide warning judgment mesh information, weather warnings, typhoon information, earthquake information, heavy rain warning (flooding) risk distribution information, etc. The meteorological disaster information data distribution unit A2 distributes the data of the meteorological disaster information announced by the meteorological disaster information announcement unit A1 in a usable (processable) format.
The meteorological disaster information acquisition unit 11 (see Figure 1) of the information providing server 1 acquires meteorological disaster information data distributed by the meteorological disaster information data distribution unit A2 (e.g., landslide warning determination mesh information, information on the risk distribution of heavy rain warnings (flooding), earthquake information, etc.).

In the example shown in Figure 12, the first judgment unit 13 (see Figure 1) of the information providing server 1 judges whether or not the user's house is included in a warning area (for example, any of the six mesh areas shown in Figure 3 (A)) in landslide warning judgment mesh information, information on the distribution of risk of heavy rain warnings (flooding), earthquake information, etc.
When the first determination unit 13 determines that the user's home is included in the alert area, the content generation unit 14 (see FIG. 1) of the information providing server 1 generates alert content based on the meteorological disaster information acquired by the meteorological disaster information acquisition unit 11. In detail, the content generation unit 14 generates, as alert content, an automated voice message indicating the danger level of the mesh area including the user's home (see FIG. 3(A)) as "very dangerous" and the danger levels of the surrounding mesh areas that are mesh areas located around the mesh area including the user's home.
The content distribution unit 15 (see FIG. 1) of the information providing server 1 transmits the automated voice message as the alert content generated by the content generation unit 14 to the terminal device (telephone) B3 used by the user.

As described above, in one example of the information provision system X of the third embodiment, when a user's home is included in a surveillance area, an automated voice message indicating the danger level of the mesh area including the user's home and the danger level of the surrounding mesh areas is sent to a terminal device (telephone) B3 used by the user. Therefore, in one example of the information provision system X of the third embodiment, even if the user is unable to operate a smartphone, personal computer, etc., the user can understand the danger level of the mesh area including the user's home and the danger level of the surrounding mesh areas.

As described above, in one example of the information provision system X of the third embodiment, the first determination unit 13 determines whether or not the user's home is included in a warning area in landslide warning determination mesh information, information on the distribution of risk of heavy rain warnings (flooding), earthquake information, etc.
In another example of the information provision system X of the third embodiment, the first determination unit 13 may determine whether the user's home is included in a warning area in information other than landslide warning determination mesh information, information on the risk distribution of heavy rain warnings (flooding), and earthquake information, such as the risk distribution of flood warnings issued by the Japan Meteorological Agency.

In another example of the information providing server 1 of the first to third embodiments described above, the content generation unit 14 may generate information indicating the danger level of the mesh area including the user's home or content based on the information indicating the danger level as alert content to an interface (e.g., email, a dedicated application of the terminal device (smartphone) B1, etc.) that notifies the terminal devices B1 and B2.
In this example, the content delivery unit 15 transmits the alert content generated by the content generation unit 14 to the terminal devices B1 and B2 via the interface.

Although the above describes the form for carrying out the present invention using the embodiments, the present invention is not limited to these embodiments in any way, and various modifications and substitutions can be made without departing from the scope of the present invention. The configurations described in the above-mentioned embodiments and examples may be combined as appropriate.

In addition, all or part of the functions of each unit of the information provision system X in the above-mentioned embodiment may be realized by recording a program for realizing these functions on a computer-readable recording medium, reading the program recorded on the recording medium into a computer system, and executing it. Note that the "computer system" here includes hardware such as the OS and peripheral devices.
