Earthquake Relocation Studies near Local Scale Sources using Double-Difference Technique
RSF Conference Series: Engineering and Technology, 2021 Determination of the location of the hypocenter is very necessary to monitor the potential for seismic hazard. Positioning and seismic energy can help safety workers determine which areas can be mined or temporarily halted. Earthquakes in underground mines are caused by seismic induction due to mining activities such as blasting processes ...

2022年芦山MS6.1地震：发生在隐伏反冲断层上的一次中强地震
Dizhen xuebao, 2023 继2008年汶川MS8.0地震和2013年芦山MS7.0地震后，2022年6月1日在龙门山断裂带南段又发生了一次MS6.1强震，距离2013年芦山MS7.0地震震中位置仅10 km。为研究此次地震的发震断层及两次芦山地震的关系，对震后60天的余震序列进行重定位，获得了933个高精度定位结果，EW，NS和UD方向上的定位误差分别为0.15 km，0.13 km和0.23 km。余震序列在水平分布上沿北东—南西向略长，在深度上主要分布在12—20 km，10 km以浅余震很少 ...

2017年西藏米林MS6.9地震余震序列重定位和b值时空分布特征
Dizhen xuebao, 2019 本文采用双差定位方法对2017年西藏米林MS6.9地震的余震序列进行重定位，获得了较准确的余震空间分布。在此基础上，计算了米林地震震源区的b值空间分布，并结合前人资料研究了米林地震前后的b值变化。重定位结果显示：米林地震余震序列呈NW−SE向分布，主要分布在雅鲁藏布江大拐弯缝合带和比鲁构造岩片的北东边界，震源深度集中于3—20 km范围内。b值时间分布显示：米林地震震前震源区的b值降低，表明震前震源区存在较强的应力积累；地震后震源区的b值呈现跳跃式上升，反映出震源区应力释放，同时随时间的推移 ...
