摘要
从序列基本情况、序列类型、应力场、地质构造背景等方面详细分析了2010年6月5日山西阳曲MS4.6地震序列特征,结合已有研究结果,指出阳曲地震类型为主震-余震型。从其所处的构造区域以及余震展布、震源机制解结果,综合分析认为系舟山西麓断裂不是其发震断裂。
This paper analyzed earthquake sequence , stress field, tectonic environment of Yangqu earthquake with MS4 .6 on June 5th,2010.According to recent research progress, Yangqu earth-quake belonged to main shock-after shock type .Through tectonic area , distribution of after shocks and focal mechanism solution , western section of Zhoushan fault wasn ’t causative fault .
