| Abstract: | The environmental shear stress field is a dynamic field varying with time and space.Tracing and analyzing space-time dynamic variation in environmental shear stress field is one of the effective ways to predict medium and short term strong seismic risk.This paper discusses annual and monthly variations in environmental shear field in Yunnan and its surrounding areas used in medium and short term prediction of the M 5 9 Shidian earthquake on April 12,2001. |
