Main functions of earthquake early warning

Earthquake early warning refers to the early warning of places where seismic waves have not yet reached by using the characteristics that the propagation speed of seismic waves is less than that of electric waves after an earthquake. Generally speaking, the propagation speed of seismic waves is several kilometers per second, while the speed of electric waves is 300 thousand kilometers per second.

Therefore, if we can use the earthquake information obtained by the real-time monitoring network and the rapid evaluation results of the scope and degree of possible damage caused by the earthquake, we can use the short time before the arrival of destructive seismic waves to issue an early warning. The research shows that if the early warning time is 3 seconds, the casualty rate can be reduced by14%; If the warning time is10s and 60s, the casualties can be reduced by 39% and 95% respectively.
