【摘要】 运用山西大同、阳曲Ms4.6两次地震序列,结合震区地质构造和震源机制解等资料,初步探讨了大同、阳曲两次地震余震强度与科里奥利力效应的关系。表明不同的衰减特征与这两次地震的破裂机制、所处构造部位不同有关。

【Abstract】 Based on two sequences of Datong and Yangqu,Shanxi,Ms4.6 earthquakes,combined with data of geological structure and earthquake focal mechanism solutions,etc.,the preliminary study on relationship between densities of the aftershocks of these two earthquakes and Coriolis force effect is taken.Different attenuation characteristics indicate that these two earthquakes have different rupture mechanism related to the structures they are in.
