【摘要】 使用双差定位方法,对2013年4月20日08时02分芦山M 7.0地震后近10天的余震进行重新定位,获得精度较高的重定位结果;在此基础上,对余震空间分布特征进行研究,推测芦山主震的发震断层可能为大川-双石主断裂东侧的一条次级隐伏逆冲断层。更多还原

【Abstract】 The double difference location method is used in this stady to relocate the aftershocks in nearly 10 days after Lushan M 7.0 earthquake at 8 o clock 2 minutes on April 20,2013.The relocation results with higher accuracy are obtained.And on this basis,the space distribution features of aftershocks are studied,the inferred seismogenic fault may be a secondary concealed thrust fault on the east side of the Dachuan-Shuangshi main fault.更多还原
