Forecasting of possible seismogenic zones in the Dnieper-Donetsk paleorift

open access: yesГеофизический журнал, 2012
As a result of complex geologic-geophysical investigations data analysis in the territory of the Dnieper-Donets paleorift (DDP) along DSS-profiles stretched across this structure, four possible seismogenic zones were distinguished.

Upper crustal velocity and seismogenic environment of the M7.0 Jiuzhaigou earthquake region in Sichuan, China

open access: yesEarth and Planetary Physics, 2021
On August 8, 2017, a magnitude 7.0 earthquake occurred in Jiuzhaigou County, Sichuan Province, China. The deep seismogenic environment and potential seismic risk in the eastern margin of Tibetan Plateau have once again attracted the close attention of ...

Focussing on Proto-Seismogenic Zone of erosional Convergent Margin [PDF]

open access: yes, 2004
Great earthquakes in subduction zones occur after stable slip in the proto-seismogenic zone transitions to the unstable slip that characterizes seismogenic zones. Subducted material input to seismogenic zones affects this transition.

Seismogenic fault and area sources for probabilistic seismic hazard model in Slovenia

open access: yes, 2022
The Slovenian Environment Agency (ARSO) and Geological Survey of Slovenia (GeoZS) jointly developed a new seismic hazard model for the 2021 Slovenian probabilistic seismic hazard assessment (PSHA) in the scope of a seven-year project starting in 2014 ...

永清MS4.3地震和廊坊MS3.0地震的发震构造研究

open access: yesDizhen 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 ...

Cascadia Convergent Zone: An Example of Primary Convergent Seismogenic Structure

open access: yesOpen 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 ...

Crustal Seismogenic Thickness and Thermal Structure of NW South America

open access: yes, 2022
The crustal seismogenic thickness (CST) has direct implications on the magnitude and occurrence of crustal earthquakes, and therefore, on the seismic hazard of high-populated regions. Amongst other factors, the seismogenesis of rocks is affected by in-situ conditions (temperature and state of stress) and by their heterogeneous composition.

Seismic structure of western end of the Nankai trough seismogenic zone [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2002
In 1998 a seismic experiment along a 320‐km‐long profile using an air gun array and ocean bottom seismographs (OBSs) was collected in the on shore‐offshore, forearc region of the western Nankai trough seismogenic zone, southwestern Japan. This area is outside the coseismic rupture area of the 1946 Nankaido earthquake (Ms = 8.2).

High resolution upper crustal velocity and seismogenic structure of the Huoshan “seismic window” in the Dabie orogenic belt

open access: yesFrontiers in Earth Science, 2023
Huoshan “seismic window” is located in the northern margin of the Dabie Orogen belt, the contact zone between North China and the Yangtze plate, where the seismic activity is mainly concentrated in this area.

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 17, Page 6047-6069, 10 December 2026.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...
