摘要
利用矩张量反演方法反演了 1996年 6月 1日天祝 -古浪 5 .4级地震序列的震源机制 ,并与该区小震综合断层面解进行了比较。在此基础上讨论了该地震前后震源区应力场的变化特征。
The source mechnisms of the seismic sequence of Tianzhu Gulang earthquake(M5.4,June 1,1996)has been inverted using the method of seismic moment tensor,the results are compared with the ones of the synthetic fault plane solutions from the micro events in the area.On the basis of it the variation characteristics of stress field in the source area before and after the earthquake have been discussed.
