An object of this invention is to make it possible to confirm the safety of persons who have the possibility of encountering the damage of the disaster when the disaster occurred. This system receives information of the disaster occurring region A and information of subscribers in the disaster occurring region A, and stores it in the disaster region subscriber table storage unit. Then, it transmits the disaster notice to the subscriber terminal in the disaster occurring region A. When it receives information of the position of the subscriber terminal or a voluntary safety confirmation response from the subscriber terminal in the disaster occurring region A, it judges whether the subscriber is in the safe state, and stores the judgment result in the disaster region subscriber table storage unit 45. With this configuration, the occurrence of the disaster can be notified to the subscribers in the disaster occurring region A, and it becomes possible for each subscriber to judge whether he or she is in the safe state. Moreover, it may also transmit the aforementioned judgment result to the subscriber terminal as the transmission source.
