An aseismic slip pulse in northern Chile and along-strike variations in seismogenic behavior [PDF]
, 2006 We use interferometric synthetic aperture radar, GPS, and seismic observations spanning 5 to 18 years to reveal a detailed kinematic picture of the spatiotemporal evolution of fault slip in a region corresponding to the 30 July 1995 M_w 8.1 subduction ...

Cascadia Convergent Zone: An Example of Primary Convergent Seismogenic Structure
Open Journal of Earthquake Research, 2019 In this article, a case is made for very-large or primary seismogenic structures in convergent margins, based on anomalous large earthquake magnitudes (Mw 8 - 9) relative to rupture lengths. Out of 56,293 earthquakes (magnitudes ≥ 5) cataloged worldwide, the 10 largest events in transform, divergent, and interior settings average magnitudes of 7.3 - 7 ...

Unveiling seismic and density structure beneath the Vrancea seismogenic zone, Romania [PDF]
Journal of Geophysical Research: Solid Earth, 2009 The Vrancea seismogenic zone in Romania exhibits an intense intermediate‐depth seismicity, confined to a relatively small, roughly cylindrical and elongated region, whose origin is still under debate. Our three‐dimensional P and S wave velocity and density images put additional physical constraints on the existing tectonic models to a depth of 200 km ...

Dizhen xuebao, 2021 2013年2月19日四川省绵阳市三台县发生MS4.7地震，震中位于四川盆地中部基底断裂绵阳—三台—大足断裂与蒲江—三台—巴中断裂的交会区域。基于地震目录、震相报告和波形等资料，对地震序列进行重定位，采用近远震联合波形反演求解主震震源机制，结合野外地质调查对该地震的发震构造进行分析。余震序列重定位的空间展布方向为NW-SE向，与节面Ⅰ走向吻合，认为此次地震发震断裂走向为NW−SE，倾向为NE，且破裂面近于直立，发震断层在近NS向的近水平挤压应力作用下作右旋走滑错动。实地调查中未见地表破裂及地表断层行迹 ...

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

Low frequency seismogenic electromagnetic emissions as precursors to earthquakes and volcanic eruptions in Japan [PDF]
, 1991 A multipoint network was constructed in the Tokyo area for earthquake prediction using seismogenic electromagnetic emissions. The network consists of eight observation points within 50 km of each other.Each point has a digital direction-finding detector ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1157-1175, 25 April 2026.ABSTRACT This study develops a comprehensive framework for assessing time and state‐dependent aftershock damage accumulation under an M9.0 megathrust interface earthquake in the Cascadia Subduction Zone (CSZ). The framework integrates aftershock probabilistic seismic hazard analysis (APSHA) and state‐dependent fragility analysis (SDFA) within a ...

2017年8月9日精河MS6.6地震余震序列精定位及发震构造分析
Dizhen xuebao, 2019 为确定2017年8月9日精河MS6.6地震的发震构造，本文使用双差定位方法对发震时刻至2017年10月震源区所发生的余震进行了精定位，同时利用CAP波形反演方法，得到了主震的震源机制解，同时使用GPAT方法反演得到了部分余震的震源机制解，并基于两者对本次地震的发震构造予以分析。结果显示：精定位后主震位于（44.27°N，82.85°E），震源深度为17 km；主震最佳双力偶解对应的节面Ⅰ的走向为260°、倾角为51°、滑动角为84°，节面Ⅱ的走向为89.5°、倾角为39.4°、滑动角为97.4 ...
