2015年7月3日新疆皮山M_S6.5地震发生在塔里木块体与西昆仑交会地区,该地区近年来中强地震较为活跃。本文对2015年新疆皮山M_S6.5地震序列及其附近地区中强震序列b值等参数进行了研究。另外,还利用新疆台网的震相报告,采用双差定位方法对余震进行了重新定位,对皮山余震序列的主震破裂区地震活动时空变化特征进行了分析和讨论,为该地区地震危险性评估提供参考。
July 3, 2015 The Pishan M_S6.5 earthquake in Xinjiang occurred in the intersection area between the Tarim Block and the West Kunlun Mountains. In this area, the moderate-strong earthquakes are relatively active. In this paper, the parameters of the M_S6.5 earthquake sequence in Pishan, Xinjiang and the b value of moderate-strong earthquakes in the vicinity of 2015 are studied. In addition, the seismic phase report of Xinjiang’s Xinjiang Uygur Autonomous Region Network was used to locate the aftershocks by the double-difference positioning method. The spatial and temporal variations of the seismic activity in the main earthquake rupture zone of the Pishan aftershock sequence were analyzed and discussed, Sex assessment for reference.
