  The operation of the disaster safety confirmation system of this embodiment will be described with reference to FIG. First, when a disaster occurs, the safety confirmation server receives disaster information from the outside (S1). Upon receiving the disaster information, the server sends a request for safety information to the terminal (S2). The requested terminal first requests the user to manually input safety information (S3), and waits for a certain period of time (S4). The request for inputting the safety information can be made, for example, by generating an audible sound and then prompting the input by displaying an input screen on the LCD display unit. If safety information is input within a certain time, the safety information is transmitted from the terminal side to the server side (S7). Then, the processing on the terminal side ends. When there is no input by the user within a certain time, the position information measuring unit 13 measures the position information of the terminal. The terminal acquires information about the terminal, such as the user's emergency contact information registered in advance in the storage unit of the terminal, information such as the mobile phone number that identifies the terminal, and the measured location information of the terminal (S5). Then, the acquired information is transmitted from the terminal to the server (S6). When the information request from the server is the second time or later, the movement information may be calculated from the difference from the initial position information as the information about the terminal, and may be additionally transmitted. Further, after the first request for information, an operation for acquiring more detailed position information at regular intervals may be started. Further, the movement amount of the terminal may be calculated using the acceleration detected by the sensor unit. In addition, if the physical information of the user who uses the terminal is previously registered in the storage unit as information related to the terminal, this kind of information may be transmitted.

  The server receives information transmitted from the terminal (S8), and determines whether there is manual input information from the user, that is, safety information related to the user's input (S9). When there is manual input information of the user, the information is transmitted to the emergency contact (S12). Moreover, when it is an emergency such as an injury, the information may be transmitted to an emergency center or the like. If there is no user input information, it is determined whether the user is in a specific area, which is a dangerous area, from the disaster information and the position information automatically acquired and transmitted by the terminal (S10). If the location of the terminal is a safe area with a low seismic intensity, the process ends. If the location of the terminal is a dangerous area, it is determined whether the location information sent from the terminal is the first time (S11). In the first case, the location information of the terminal is sent to the emergency contact. Information including is transmitted (S13). Then, safety information is continuously requested from the terminal (S2). If the location of the terminal is a dangerous area and the location information sent from the terminal is the second or more times, in addition to the location information, information including movement information is transmitted to the emergency contact (S14). . When the terminal has been stopped at the same place for a long time, the movement information has no movement amount and is information that suggests that the user is likely to be damaged. After reporting to the emergency contact, continue to request safety information from the terminal (S2). These processes are mainly performed by the processing unit of the server.
