Next, the user extraction unit 301 refers to the total information stored in the storage unit 210 of the total analysis device 20, and extracts users to whom the issued disaster prevention information is to be notified (step S33). That is, the user extracting unit 301 extracts data from the disaster prevention information issuance locations (areas, transportation facilities, roads, facilities) of "frequently visited areas", "frequently used transportation facilities", "frequently used roads", and "frequently visited facilities". All users corresponding to any of the above are extracted as notification targets. Next, the notification processing unit 302 notifies the terminal 10 of each extracted user of the details of the disaster prevention information issued (step S34), and updates the notification history stored in the storage unit 310 (step S35).

According to the disaster prevention information notification system of the present embodiment, user behavior information acquired during normal times is aggregated and analyzed with reference to external data. By extracting users who are concerned about disaster prevention and notifying them of disaster prevention information, suitable disaster prevention information can be automatically provided regardless of the user's current location or even if the user does not specify in advance the disaster prevention information acquisition area. The terminal 10 of the user can be notified.
