Assessing infrequent large earthquakes using geomorphology and geodesy in the Malawi Rift [PDF]
, 2015 In regions with large, mature fault systems, a characteristic earthquake model may be more appropriate for modelling earthquake occurrence than extrapolating from a short history of small, instrumentally observed earthquakes using the Gutenberg–Richter ...

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 ...

Deep lithospheric structures along the southern central Chile Margin from wide-angle P-wave modellilng [PDF]
, 2009 Crustal- and upper-mantle structures of the subduction zone in south central Chile, between 42 degrees S and 46 degrees S, are determined from seismic wide-angle reflection and refraction data, using the seismic ray tracing method to calculate minimum ...

Crustal Seismogenic Thickness and Thermal Structure of NW South America
, 2022 Abstract. The crustal seismogenic thickness (CST) has direct implications on the magnitude and occurrence of crustal earthquakes, and therefore, on the seismic hazard of any region. Amongst other factors, the seismogenesis of rocks is affected by in-situ conditions (temperature and state of stress) and by the rocks’ heterogeneous composition.

Thermal structure and megathrust seismogenic potential of the Makran subduction zone [PDF]
Geophysical Research Letters, 2013 The Makran subduction zone experienced a tsunamigenic Mw 8.1 earthquake in 1945 and recent, smaller earthquakes also suggest seismicity on the megathrust; however, its historical record is limited and hazard potential enigmatic. We have developed a 2‐D thermal model of the subduction zone.

Dizhen xuebao, 2019 为研究川滇地区地壳密度的时空演化特征与强震孕育的关系，本文基于2011—2014年川滇地区的重力复测资料，利用阻尼最小二乘反演算法，获得了川滇地区0—50 km深度范围内分辨率为55 km×55 km×10 km （长×宽×高）的三维动态密度变化模型。以所获取的动态密度变化为依据，分析了川滇地区三维密度变化特征与2013年四川芦山MS7.0、2014年云南鲁甸MS6.5和四川康定MS6.3地震的关系，并由此对强震重点构造部位的深部地壳结构特征、孕震背景及区域动力学过程进行了深入分析。结果显示 ...
