Structuralkinematic identification of seismogenic zones of the Zagros system (according to the solutions of the mechanisms of earthquake)

Геофизический журнал, 2013
On the base of results of analysis of structuralkinematic parageneses of ruptures and displacements in the earthquakes foci of the foldedfaulted Zagrosa system the main types of seismogene sis have been substantiated and their stereographic models ...

Active faults in the epicentral and mesoseismal Ml 6.0 24, 2016 Amatrice earthquake region, central Italy. Methodological and seismotectonic issues

Annals of Geophysics, 2016
The August 24, 2016 Amatrice earthquake (Ml 6.0) struck a region of the central Apennines (Italy) where several active faults were known since decades, most of which are considered the surface expression of seismogenic sources potentially able to rupture

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

Journal 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).

Strike-slip fault terminations at seismogenic depths : the structure and kinematics of the Glacier Lakes fault, Sierra Nevada United States

, 2008
Structural complexity is common at the terminations of earthquake surface ruptures; similar deformation may therefore be expected at the end zones of earthquake ruptures at depth.

Seismogenic structure behaviour revealed by spatial clustering of seismicity in the Umbria-Marche Region (Central Italy)

Annals of Geophysics, 1998
Time variations in the spatial distribution of earthquake epicentres are analyzed by application of the fractal correlation dimension method. The zone under investigation is located in Central Italy, bounded in longitude by 12.0 and 14.4 degrees east and

2018年5月28日吉林松原MS5.7地震发震构造分析

Dizhen xuebao, 2020
利用黑龙江、吉林、内蒙古三省数字地震台网的三分量宽频带波形资料对2018年5月28日吉林省松原市宁江区发生的MS5.7地震进行了全波形矩张量反演，获取了此次地震的震源机制解和矩心位置；并使用震源-矩心方法讨论了该地震的发震断层。研究结果显示：松原MS5.7地震的矩震级为MW5.2，矩心位置为（45.225°N，124.685°E），矩心深度为7 km。震源机制解参数显示：该地震为走滑型；节面Ⅰ的走向、倾角和滑动角分别为217°，82°和164°；节面Ⅱ的走向、倾角和滑动角分别为309°，74°和8 ...

Thermal squeezing of the seismogenic zone controlled rupture of the volcano-rooted Flores Thrust [PDF]

, 2021
Temperature plays a critical role in defining the seismogenic zone, the area of the crust where earthquakes most commonly occur; however, thermal controls on fault ruptures are rarely observed directly. We used a rapidly deployed seismic array to monitor

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 ...
