摘　　要：收集2009—2022年内蒙古东部地区6次和邻区13次M≥4.0地震宽频带地震波形资料,采用CAP(Cut and paste)方法进行震源机制解反演。结果表明,内蒙古东部地区震源机制以走滑型为主,应力场方向呈NEE向。This study collects broadband seismic waveform data of 6 M≥4.0 earthquakes and 13 M≥4.0 earthquakes in eastern Nei Monggol and adjacent areas,respectively,from 2009 to 2022 to invert their focal mechanism solutions using the CAP(Cut and Paste)method.The results show that the focal mechanism in eastern Nei Monggol is mainly strike-slip,and the stress field direction is NEE.

关 键 词：内蒙古东部地区 波形拟合 震源机制
