Community alarm system
When an earthquake occurs, the EQ guard near the epicenter detects the P wave and sends the information to the data center. The epicenter is identified based on the information collected in the data center, and the magnitude, depth, and latitude / longitude are delivered to each terminal. The terminal calculates the seismic intensity and the number of seconds of arrival from the epicenter information and issues an alarm.
The information gathered from each EQ guard can display real-time waveforms through the server.
