The 26 December 2003 (Mw 6.6) Bam earthquake is one of the most destructive events in the recorded history of Iran. Good variable-slip fault models and precise aftershock data enabled us to calculate Coulomb stress changes on the surrounding faults ...

In this study the relationship between brittle rocks’ behaviour and uniaxial compression stress is obtained based on the Mohr-Coulomb failure criterion and the behavioural characteristics of brittle rocks under uniaxial compression stress are investigated.

ABSTRACT The Coulomb failure stress (CFS) criterion based on the Mohr-Coulomb friction theory is commonly used to explain physical mechanisms governing injection-induced seismicity. While the CFS criterion can evaluate the onset of fault reactivation caused by fluid perturbations, it cannot tell the kinematic ...

Using a seismicity simulation program based on the Coulomb-Navier failure criterion and the stress transfer mechanism, we added extensions to make the model compatible with different input files and to increase computational efficiency. After testing with a two-vertical-parallel-fault model, we applied this model to the Taiyuan region.

Crack-tip Stress Field, Coulomb Failure, and the Spectral Characteristics of Tensile Rupture
Proceedings, 2012Summary By combining recent empirical observations with classical theory from fracture mechanics and earthquake seismology, we develop a simple geodynamical framework for simulation of frac-induced microseismicity. Using analytical expressions for crack-tip stress, we apply the Coulomb failure criterion to obtain a scalar field with units of stress ...

AbstractThe Coulomb stress change has been widely employed to interpret mainshock‐mainshock and mainshock‐aftershock triggering as well as interactions amongst earthquake faults and volcanoes. This quantitative index is computed based on the Coulomb failure criterion and is a function of fault parameters including the source and receiver fault ...
