Mainshock‐Induced Stress Changes Modulate Initial Aftershocks on Complex Branching Faults of the 2019 Ridgecrest Earthquake

open access: yesGeophysical Research Letters
Large earthquakes can activate complex aftershock fault networks. In such systems, what controls the spatiotemporal evolution of early aftershocks remains a critical yet unresolved problem.

Bath's law Derived from the Gutenberg-Richter law and from Aftershock Properties [PDF]

open access: yes, 2003
The empirical Bath's law states that the average difference in magnitude between a mainshock and its largest aftershock is 1.2, regardless of the mainshock magnitude. Following Vere-Jones [1969] and Console et al.

The Generation of the Target Aftershock Spectrum Based on the Conditional Mean Spectrum of Aftershocks

open access: yesBuildings, 2023
Numerous studies have examined the responses of various structures to the mainshock–aftershock (MS–AS) ground motion, and the MS–AS ground motions are very important as the input.

Aftershock production rate of driven viscoelastic interfaces [PDF]

open access: yes, 2014
We study analytically and by numerical simulations the statistics of the aftershocks generated after large avalanches in models of interface depinning that include viscoelastic relaxation effects.

Mainshock‐Aftershock Clustering in Volcanic Regions

open access: yesGeophysical Research Letters, 2018
Earthquakes break their general Poissonean behavior through two types of seismic bursts: swarms and mainshock‐aftershock sequences. The former is commonly thought to dominate in volcanic and geothermal regions, but aftershock production, including within

Generation of infrasonic signals during earthquakes under Lake Hovsgool (Northern Mongolia) on December 5, 2014

open access: yesSolar-Terrestrial Physics, 2018
The paper discusses the results of the detection of seismic and infrasonic waves generated by a major earthquake and its aftershock (the moment magnitude MW=4.9 and MW=4.2 respectively), which occurred in northern Mongolia under Lake Hovsgool on December

2014年新疆于田MS7.3地震的发震构造及余震特征

open access: yesDizhen xuebao, 2021
利用2014年10月至2019年9月期间欧空局Sentinel-1卫星采集的合成孔径雷达数据分析了2014年2月12日新疆于田MS7.3地震的震后形变场。结果表明,此次地震造成了南硝尔库勒断裂上明显的震后形变,首次从地震形变场的角度验证了此次地震的发震构造为NE向的左旋走滑断裂,而非部分研究所认为的近NS向断裂。由合成孔径雷达干涉测量得到的多年平均速率图显示主震的西侧仅出现了少量震后余滑且仍为强闭锁区,这意味着2008年和2014年于田两次MS7.3地震之间的区域仍存在发生强震的风险 ...

Complex networks of earthquakes and aftershocks [PDF]

open access: yes, 2004
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviates the need to distinguish main shocks from ...

Fault plane solutions of the 1993 and 1995 Gulf of Aqaba earthquakes and their tectonic implications

open access: yesAnnals of Geophysics, 1997
The stereographic projection of P-wave first motions for the 3 August 1993 Gulf of Aqaba earthquake, its largest aftershock (16 h 33 min), and for the 22 November 1995 earthquake were constructed using the polarity readings of regional and teleseismic ...

The Uglovoye Podnyatiye Earthquake on December 20, 2018 (Mw = 7.3) in the Junction Zone between Kamchatka and Aleutian Oceanic Trenches

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The paper presents the first results of integrated research of the strong seismic event (Uglovoye Podnyatiye earthquake (UPE) with a magnitude of Mw=7.3) that occurred on December 20, 2018 in the junction zone between the Kuril-Kamchatka and Aleutian ...
