| 摘 要： | 利用青海省地震台网玉树、曲玛莱、杂多、昌都等地震台以及玉树7.1级地震后临时布置的台站产出的数字化观测资料,采用Pg、Sg最大振幅比的方法,计算了2011年6月26日青海囊谦Ms 5.2级地震震源机制解,结果显示该区地震序列以走滑地震为主,仅有一个余震的震源机制解为逆冲类型.

| Abstract: | Using digital observation data recorded by seismic stations such as Yushu, Qumalai, Changdu and temporary seismic network stations after the Yushu Ms 7. 1 earthquake, the focal mechanisms of the Nangqian Ms5.2 earthquake on June 26th ,2011 and some large aftershocks are calculated by the maximum amplitude ratio of Pg and Sg wave, it is found that the earthquake sequence are mainly strike - slip type, while there is only one thrust event. |
