Abstract

The seismicity with magnitude that is equal to or greater than 3.0 before an earthquake(Ms≥5.0)since 1988 occurred in Sichuan and Yunnan provinces is analyzed in this paper.Our study results show that before a medium-strong earthquake,a non-linear trending intensifying change process of the seismicity intensity and the frequency appears.And according to this increasing change process we guess an earthquake or a followed earthquake or no earthquake may occur in a period of time within a whole limited area.
