Abstract: According to the characteristics of strong earthquake group preparation in China's mainland and based on the theory of strong seismic stimulus, we conduct the At value scanning for strong earthquakes with MS≥7.0 in Southwest China, then we briefly analyze and mark the methods with R-value. At last, the seismically risk zone is predicted.

Key words: Strong earthquake group preparation, Atvalue, R-mark, Risk
