2017年伊朗MW7.3地震的震后余滑分布及其对2018年MW6.0地震的触发影响

open access: yesDizhen xuebao, 2022
收集了覆盖监测区域的Sentinel-1卫星雷达影像,利用短基线集干涉测量技术提取了2017年伊朗萨波尔扎哈布MW7.3地震后283天的地表时序形变,通过二步法反演得到其震后余滑分布,之后采用差分干涉技术获取了2018年发生于同一地区的贾万鲁德MW6.0地震的同震形变场,并将反演所得的发震断层参数作为应力计算的接收断层参数,来分析2017年MW7.3强震及其震后活动对2018年贾万鲁德MW6.0地震的触发影响。结果表明:萨波尔扎哈布地震的震后形变主要由孕震断层面的余滑运动所致 ...

Revisiting the seismic hazards of faults surrounding the 2022 Ms6.8 Luding earthquake, Sichuan, China

open access: yesGeomatics, Natural Hazards & Risk, 2023
The occurrence of the Ms6.8 Luding earthquake on 5 September 2022 filled the seismic gap in the southeastern segment of the Xianshuihe fault zone and transferred stress to the surrounding faults, which attracted much more attention to the seismic hazard.

Long-Term Recurrence Pattern and Stress Transfer along the Kefalonia Transform Fault Zone (KTFZ), Greece: Implications in Seismic Hazard Evaluation

open access: yesGeosciences, 2023
An effort is exerted to investigate the recurrence pattern of large earthquakes (Mw ≥ 6.0) in the Kefalonia Transform Fault Zone (KTFZ), Greece, by considering the incorporation of the 74-year (1948–2022) evolving stress field. Four earthquake occurrence

Earthquakes in the Shadows: Why Aftershocks Occur at Surprising Locations

open access: yesThe Seismic Record, 2022
For decades there has been a debate about the relative effects of dynamic versus static stress triggering of aftershocks. According to the static Coulomb stress change hypothesis, aftershocks should not occur in stress shadows—regions where static ...

Tectonic tremors in the Northern Mexican subduction zone remotely triggered by the 2017 M w8.2 Tehuantepec earthquake

open access: yesEarth, Planets and Space, 2021
Surface waves from the 2017 M w8.2 Tehuantepec earthquake remotely triggered tectonic tremors in the Jalisco region, approximately 1000 km WNW in the northern Mexican subduction zone.

九江—瑞昌地区显著地震动态库仑破裂应力变化分析

open access: yesDizhen xuebao, 2019
为了探究九江—瑞昌地区内的地震活动是否存在动态应力触发关系,本文选用多层黏弹性介质模型,计算了2005年九江—瑞昌MS5.7地震和2011年瑞昌—阳新MS4.6地震产生的动态库仑破裂应力变化。结果显示:九江—瑞昌MS5.7地震产生的动态库仑破裂应力变化,能触发其北东方向的53次地震;瑞昌—阳新MS4.6地震发生后15天内,小震活动增强区及九江—瑞昌MS5.7地震震源区的多次地震活动,可能与其动态应力触发作用有关。

Megathrust Stress Drop as Trigger of Aftershock Seismicity: Insights From the 2011 Tohoku Earthquake, Japan

open access: yesGeophysical Research Letters, 2023
Numerous normal‐faulting aftershocks in subduction forearcs commonly follow large megathrust earthquakes. Postseismic normal faulting has been explained by stress changes induced by the stress drop along the megathrust. However, details of forearc stress
