麦宿断裂地震地表破裂带的发震构造分析

Dizhen xuebao
野外地质调查发现金沙江断裂带北段麦宿断裂附近发育长约50 km的地震地表破裂带，其最大垂直位移为2 m。基于该地震地表破裂带周围架设的密集地震台阵于2020 年 12 月至 2022 年 7 月期间记录到的连续波形数据，采用双差定位方法对（31.55°N—31.85°N，98.31°E—98.98°E） 区域内的578个地震事件进行定位，并利用基于P波初动的HASH方法对定位得到的地震事件进行震源机制解反演，获得了37组震源机制解 ...

Seismogenic frictional melting in the magmatic column

, 2014
Lava dome eruptions subjected to high extrusion rates commonly evolve from endogenous to exogenous growth and limits to their structural stability hold catastrophic potential as explosive eruption triggers.

Hazard in the Gulf of Cadiz: review of the large seismogenic structures

, 2018
The Gulf of Cadiz is located at the SW Iberian Margin and hosts the African-Eurasian plate boundary. This is one of the most seismogenic areas in Western Europe, where historical and instrumental earthquakes occurred, ranging from Mw 6 to 8.5, and some of them triggered destructive tsunamis.

联合InSAR和热红外技术研究2023年甘肃积石山MS6.2地震构造活动特征

Dizhen xuebao
联合使用合成孔径雷达干涉测量（InSAR）与热红外遥感技术，系统分析了2023年甘肃积石山MS6.2地震的同震形变场、发震断层参数、滑动分布、库仑应力变化及震前热异常特征。利用Sentinel-1A升降轨合成孔径雷达数据，通过差分干涉测量获取了积石山地震的同震形变场，结果表明：形变以抬升为主，升、降轨最大雷达视线向位移分别约为6.5 cm和7.2 cm，形变区集中分布于拉脊山南、北缘断裂之间。采用四叉树采样与贝叶斯反演方法，在合理模型约束下，反演得到积石山地震发震断层的几何参数为：走向324°±1 ...
