摘 要: | 针对2013年1月29日发生在中哈交界Ms6.1地震,基于新疆数字台网中心宽频带波形记录,采用CAP方法反演了其震源机制解。结果显示:该次地震震源深度为27km,其中一个节面走向161°,倾角76°,滑动角-164°,与哈佛大学计算结果一致;结合余震空间分布和GPS观测结果,判定该节面为破裂面,同时推断该处有一发震断层,其走向NWW、倾角较大、断错性质为右旋走滑型。

Abstract: | We adapted CAP method to calculate focal mechanism solution of Kazakhstan earthquake with Ms6.1 on Jan 29'h ,2013 based on broadband digital wave in Xinjiang. The result showed: the focal depth is about 27 km, one nodal plane strike is 161°, dip 76° ,rake - 164° which were similar to Hanford's results. According to distribution of aftershocks and GPS data, we found there is a causative fault with NWW direction ,with large dip and belongs to right-lateral strike-slip. |
