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 ...

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.

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-

Melting Dynamics in Thermal and Stress Driven Coulomb Clusters

Physica Scripta, 2001
The microscopic dynamical responses of a two dimensional circular Coulomb cluster to thermal excitations and to the external force along a narrow band through its center are studied. The strong competition between the cirular boundary and the inner domain with triagular lattice leads to the nonuniform melting of the cluster.

Modified Mohr-Coulomb Theory for Triaxial State of Stress

Applied Mechanics and Materials, 2015
The Mohr-Coulomb failure theory presents the major drawback that can be applied only for plane state of stress. In this paper, we propose a modification of the Mohr-Coulomb theory that might eliminate this disadvantage. It is proposed to replace the three Mohr's circles for spatial state of stress with one “virtual circle” with diameter σ1-σ3±2ρ ...

Consistent Regularization of Induced Coulomb Stresses in Displaced Faults

2023
This note provides unregularized and regularized closed-form analytical expressions for the depletion-induced or injection-induced pre-slip Coulomb stresses in two-dimensional displaced dip-slip faults. The regularization serves to remove logarithmic singularities and jump-discontinuities in the unregularized formulation.

Dynamic Stresses, Coulomb Failure, and Remote Triggering

Bulletin of the Seismological Society of America, 2008
Dynamic stresses associated with crustal surface waves with 15–30-sec periods and peak amplitudes 5 km). The latter is consistent with the observation that extensional or transtensional tectonic regimes are more susceptible to remote triggering by Rayleigh-wave dynamic stresses than compressional or transpressional regimes.

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.
