【摘要】 采用双差地震定位法,对2008年1月—2013年11月重庆及邻区的荣昌、綦江、石柱、巫山—湖北巴东、巫溪地区地震进行精定位。结果表明,重新定位后地震震源位置比常规地震定位法得到的结果更加精确。荣昌、綦江、石柱地区地震震中呈条带状分布较明显,与断裂构造一致性较好;巫山—巴东、巫溪地区地震震中成团现象明显,地震成因较复杂。更多还原

【Abstract】 In this article, earthquakes from January 2008 to November 2013 in areas of Rongchang, Qijiang, Shizhu, Wushan add Badong and Wuxi in Chongqing and its adjacent area are repositioning by double-difference earthquake location method. The results show, the repositioning of seismic source position is more accurate than conventional seismic location method. In addition, earthquake epicenters in Rongchang, Qijiang, and Shizhu are obvious banded distribution, consistent with fault structure. Earthquake epicenters in Wushan add Badong and Wuxi are obvious distributed into groups, and causes of earthquakes are more complex.更多还原
