DISASTER NOTIFICATION SYSTEM, DISASTER NOTIFICATION SERVER, DISASTER QUICK REPORT TERMINAL, METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a disaster notification system for accurately calculating a time until a natural disaster arrives at a disaster early warning terminal by use of present time measured in the disaster early warning terminal. SOLUTION: In this disaster notification system, a disaster notification server 100 calculates expected arrival time when the natural disaster arrives at location of the disaster early warning terminals 200-1 to n when the natural disaster occurs. The disaster notification server 100 transmits the calculated expected arrival time to the disaster early warning terminals 200-1 to n. The disaster early warning terminal 200-1 to n measures time, acquires the present time measured in the disaster early warning terminal 200-1 to n when receiving the expected arrival time from the disaster notification server 100, and calculates the time until the natural disaster arrives at the disaster early warning terminal 200-1 to n on the basis of the expected arrival time and the present time.
