Abstract:

In recent years,the ＂earthquake early warning＂（EEW） technology has been developed rapidly around the world,some cases show that EEW has successfully provided seismic early warning information and got earthquake disaster mitigation effectiveness.In this paper,the approaches of the EEW,including front wave detection,using the P wave,onsite warning and regional warning are introduced,and the applications of EEW in Mexico,Japan,Turkey,China Taiwan,Romania and other countries and region areas are introduced also.Some problems and challenge in the earthquake early warning,as well as its perspective are analyzed.
