【摘要】 对2012年6月30日新疆新源、和静交界MS6.6地震基本参数、震源机制解、构造背景、地震序列特征及震前地震活动图像异常特征等进行了分析。结果显示,本次地震序列为主-余型,发震构造为北天山地震带喀什河断裂、那拉提断裂及阿吾拉勒山南缘断裂的交汇区,震源断错性质为走滑型。地震活动表明,震前震源区周围地区存在明显的空区和条带等中、短期异常,但是没有短临异常出现。更多还原

【Abstract】 By analyzing seismic parameters,focal mechanism solution,tectonic setting,sequence characteristics and seismicity anomalies of Xinyuan,Hejing earthquake with MS6.6 on June 30th,2012,the results show the earthquake belongs to main shock-after shock type.The causative structure located at intersection of Kashi river fault,Nalati fault and southern region of Awulale fault in Northern Tianshan seismic belt and the earthquake was strick-slip.There are obvious medium and short term anomalies such as seismic gap,seismic belt near focal region but without short-impending anomaly before the earthquake.更多还原
