Complete Coulomb failure stress changes and stress triggering of Yunnan Longlingearthquake sequence

open access: yesChinese Journal of Geophysics, 2007
The complete Coulomb failure stress changes caused by the 1976 Ms73, Ms74 Yunnan Longling double main earthquakes are calculated. And dynamic and static stress triggering effects on the after earthquake sequence are studied. The results show that the second main earthquake is subjected to the triggering effect of dynamic and static Coulomb ...

Effects of Coulomb stress change on M > 6 earthquakes in the Caucasus region

Physics of the Earth and Planetary Interiors, 2019
Abstract Coulomb stress variations may trigger earthquakes, while the stress transfer process is not clear. In this paper, Coulomb stress changes are investigated for the sequences of strong earthquakes in the Caucasus region, which followed the 1988 Mw6.8 in Spitak, the 1991 Mw6.9 in Racha and the 2000 Mw6.2 in Baku.

Sensitivity of Coulomb stress change to the parameters of the Coulomb failure model: A case study using the 2008 Mw 7.9 Wenchuan earthquake

open access: yesJournal of Geophysical Research: Solid Earth, 2014
The Coulomb stress change has been widely employed to interpret mainshock-mainshock and mainshock-aftershock triggering as well as interactions amongst earthquake faults and volcanoes.

PETRINJA EARTHQUAKE AFTERSHOCKS – LOCATIONS, FOCAL MECHANISMS AND RELATED COULOMB STRESS CHANGE

2nd Croatian Conference on Earthquake Engineering ‒ 2CroCEE, 2023
Almost 14000 aftershocks have been located in the first six month after the Mw 6.4 Petrinja earthquake of 29 December 2020. Most epicentres lie close to the NW–SE striking right-lateral causative fault, but considerable activity has been recorded in the surrounding area up to about 50 km away.

Effect of Earth Models on Coulomb Stress Change Caused by Surface Load

Pure and Applied Geophysics, 2021
Based on the elastic spherical Earth models, this study presents the radial Love numbers and Green’s functions of the surface load problem, then evaluates the effect of different Earth models on the Coulomb stress changes due to elastic deformation by surface load. First of all, the radial load Love numbers are introduced and verified by comparing them

Changes of Coulomb Failure Stress during Stimulation

Proceedings, 2011
For the prediction of future reservoir performance, knowledge of the spatio-temporal evolution of the geothermal reservoir in response to stimulation and production is a key issue. During the project for developing an Enhanced Geothermal System at Soultz-

The Stress Triggering of Aftershocks by Badong M5.1 Mainshock from Coulomb Stress Changes

Advanced Materials Research, 2014
TheCoulomb stress changes are usually adopted to make analysis on faultinteractions and stress triggering. This paper mainly deals with Coulomb stresschange of mainshock and affect on aftershocks. We preliminarily conclude thatthe mainshock produce Coulomb stress change on aftershocks most behavingpositive and triggered them.

Coulomb stress changes: From earthquakes to underground excavation failures

International Journal of Rock Mechanics and Mining Sciences, 2009
Abstract Evidence from shallow tunnels and mines indicates that, in certain cases, deformation and failure are not confined to the vicinity of the excavation front, as is widely believed. This situation has recently been described as lateral strain propagation from a “source” to remote parts of the excavation through low-strength rocks.

Seasonal stress inversion trends and Coulomb stress changes of RTS in Song Tranh2 reservoir, Vietnam

2022
<p>The Song Tranh 2 hydropower construction is located in the Quang Nam province (central Vietnam), it has a reservoir volume of 740 million cubic meters of water and a dam height of 96 m. The reservoir was filled to capacity for the first time in February 2011. The seismicity in the vicinity of reservoir is example of reservoir triggered
