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 ...

Revealing the slip distribution and seismogenic structure of the magnitude 6.2 Jishishan (Gansu) earthquake in 2023 through multi-source InSAR observations

Geo-spatial Information Science
On 18 December 2023, Jishishan County in Gansu Province, China, was struck by an earthquake with magnitude 6.2, resulting in considerable loss of life and property. The seismogenic fault and rupture model of the event has sparked significant controversy,

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 ...

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 ...

Seismogenic Structures in Subduction Zones

Surveys in Geophysics
Abstract Recent studies of high-resolution seismic tomography of source zones of large crustal earthquakes, megathrust earthquakes, and intraslab earthquakes are reviewed, which shed new light on seismogenic structures and fluids in subduction zones.

Combined Vertical and Horizontal Components of Near‐Source Earthquakes and Impact on Base‐Isolated Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 781-803, March 2026.
ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

Abrupt Along‐Strike Change of Shallow Seismicity in Central and Southern Myanmar: Insights From High‐Resolution Local‐Earthquake Catalogs and Focal Mechanisms

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Myanmar's high seismic hazard is underscored by the 2025 Mw 7.7 earthquake on the Sagaing Fault, yet its seismicity patterns and underlying controls remain poorly understood. Using new seismic data from the 2nd‐phase array of the China‐Myanmar Geophysical Survey in the Myanmar Orogen, we construct a high‐resolution catalog of 1,819 local ...
