摘要
利用广西台网30多年地震观测资料,根据P波初动半周期和地震震级资料测定环境剪应力的方法,测算了广西及邻区大量中小地震震源的相对剪切应力强度值,据此分析了广西及邻区环境剪应力场总体特征,给出了8次中强地震前后一年的环境剪应力值,对环境剪应力值的区域特点进行了分析。
In this paper, the ambient shear stress values of many moderate and small earthquakes sources in Guangxi and its neighboring region are determined by using the method of the P- wave first move half period and the earthquake magnitude data, and the observed earthquake data for more than 30 years in the area. Based on these, basic characteristics of ambient shear stress field are studied and the future earthquake risk areas are forecasted in Guangxi and its neighboring region.
