摘要
利用甘肃省数字地震台网的波形资料,采用CAP方法反演得到2012年5月3日金塔-阿拉善盟5.4级地震的震源机制解。震源性质为走滑型,断层破裂面为78°,主压应力P轴方向为N32°E,震源深度为9km。
Using the waveform data from the Digital Seismological Network of Gansu province,adopting CAP method,the focal mechanism of the 5.4 earthquake which occurred at JinTan-Alashanmeng on May 3,2012,is obtained.It shows that the character of focus is strike-slip,the fault rupture plan is 78°,azimuth of maximum principal compressive stress,P,is N32°E,and the focal depth is 9 km.
