1996年6月1日甘肃省天祝-古浪5.4级地震的发震构造探讨

STUDY ON THE CAUSATIVE STRUCTURE OF THE TIANZHU GULANG M S5.4 EARTHQUAKE IN GANSU ON JUNE 1,1996

根据震区深浅地质构造特征及现场考察结果，１９９６年６月１日天祝古浪５．４级地震极震区位于古浪断裂与武威天祝断裂的交汇部位，该部位是应力积累和释放的有利场所。

According to characters of the deep and shallow tectonics in seismic area and the results of field investigation,the meizoseismal region of the Tianzhu Gulang M S5.4 earthquake on June 1,1996 is located at the intersection of Gulang fault and Wuwei Tianzhu fault,the intersection is easy to accumulate and release stress. This earthquake results from the joint action of the active faults.
