| 摘 要： | 根据全国地震台网的记录资料及前人对山西大同-阳高地震的研究结果，通过对大同-阳高地震震源机制及大同遥测地震台网的单（多）台小震综合断层面解的研究，结合当地地质构造条件，推断出大同-阳高地震的震源应力场及前震、主震、最大余震的发震断层。通过对大同-阳高地震中余震随时间分布、烈度等震线分布和构造裂缝的研究，给出了大同-阳高地震中几次主要地震的破裂方向、破裂长度等。

| Abstract: | Based on data of seismic network countrywide and research results of predecessors to Datong-Yanggao,Shanxi,earthquake,with local geologic tectonic condition,the focal stress field and the seismogenic faults of the foreshocks,main shock and aftershocks of the Datong-Yanggao earthquake are deduced through the study on focal mechanism solution to the Datong-Yanggao earthquake and synthetic fault plane solution,using small earthquakes of single(multi-) station of the Datong Telemetric Seismic Network.Rupture direction and length etc.of several primary earthquakes of Datong-Yanggao earthquake are gained through the study on time distribution of aftershocks,isoseismic intensity and tectonic fault of Datong-Yanggao earthquake. |
