Waveform inversion of the S reflector west of Spain: fine structure of a detachment fault. [PDF]
, 2005 The S reflection west of Iberia has been interpreted as a low-angle detachment fault separating crustal fault blocks from partially serpentinized mantle. We apply full waveform inversion to investigate the fine structure of S.

2003 Mw6.8 Chengkung earthquake and its related seismogenic structures [PDF]
Journal of Asian Earth Sciences, 2007 Abstract The Mw = 6.8 Chengkung earthquake on December 10, 2003 in eastern Taiwan was associated with abundant aftershocks. To explore the seismogenic mechanism and its causative fault system, we relocated the aftershocks, determined the focal mechanisms from P-wave polarities and used the Finite Dimension Source Model method to identify the fault ...

濑溪河流域地貌对泸县MS6.0地震发震构造变形的响应及其指示作用
Dizhen xuebao, 2022 以12.5 m 数字高程模型数据为基础，采用数字地貌分析方法提取了濑溪河流域的高程剖面和面积-高程积分（HI）等地貌参数，分析了2021年9月16日四川盆地东南部泸县MS6.0地震震中附近区域地貌与构造活动的响应关系。结果显示：震中西侧的螺观山和梯子崖背斜在震中的南北两端存在明显的缩短量差异；HI条带状低值区的展布方向与流域内构造的方向一致，HI高值区位于华蓥山两条断裂夹持的谷地，但在震中附近存在WNW向的HI低值带。综合分析认为，泸县地震震中附近应存在一走向为WNW的隐伏构造 ...

Dizhen xuebao, 2020 基于首都圈数字地震台网的宽频带资料，首先采用CAP方法确定了永清MS4.3地震和廊坊MS3.0地震的震源机制解：永清地震节面Ⅰ的走向、倾角和滑动角分别为52°，62°和−140°，节面Ⅱ的走向、倾角和滑动角分别为300°，55°和−35°；廊坊地震节面I的走向、倾角和滑动角分别为48°，57°和−147°，节面Ⅱ的走向、倾角和滑动角分别为299°，63°和−38°。两次地震的震源机制解较为一致，推测它们可能具有相同的发震断层。利用近震转换波获得两次地震的震源深度，分别为19 km和13 km ...
