Breaking up the hanging wall of a rift-border fault: The 2009 Karonga earthquakes, Malawi [PDF]

, 2010
The southern East African Rift has an unusually large seismogenic thickness (35–40 km), which is responsible for wide tilted basins and extremely long faults with the potential for M7-8 normal-faulting earthquakes.

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 ...

2022年1月8日青海门源MS6.9地震序列重定位和震源机制解研究

Dizhen xuebao, 2022
2022年1月8日青海省海北州门源县发生MS6.9地震，震后产生了长约22 km的地表破裂带，青海、甘肃和宁夏等多地震感强烈。本文基于区域地震台网资料，通过多阶段定位方法对门源MS6.9地震早期序列（2022年1月8日至12日）进行了重定位，并利用gCAP方法反演了主震和MS≥3.4余震的震源机制和震源矩心深度，计算了现今应力场体系在门源MS6.9地震震源机制两个节面产生的相对剪应力和正应力。结果表明：门源MS6.9地震的初始破裂深度为7.8 km，震源矩心深度为4 km ...

Structure-controlled asperity on the generation of large earthquakes

地球与行星物理论评, 2022
The occurrence of large earthquakes is not only related to the fault geometry and state of stress accumulation, but also closely related to the structure of surrounding rocks.
