【摘要】 分别采用CAP、矩张量解和Snoke三种方法反演2010年1月24日山西河津MS4.8级地震的震源机制解,结果显示,CAP和矩张量节面解一致性好,Snoke方法略有差异,从实用性看,CAP方法可直接利用现有处理系统震相数据,相比其他两种方法在中等发生后产出速度快;Snoke方法更适用于中小地震震源机制解的测定。更多还原

【Abstract】 Focal mechanism solution of the Jan. 24,2010 Hejin,Shanxi earthquake of M_S4. 8 is inversed by the methods of CAP,CMT and Snoke. The result indicates that consistency of CAP and plane solution of CMT is good,while the method of Snoke is slightly different; and that from the practical point of view,the method of CAP can directly use the seismic phase data of existing processing system and compared to the other two methods,its output speed after the moderate earthquakes is quick,and the method of Snoke is more applicable to the measurement of focal mechanism solution of moderate and small earthquakes.更多还原
