Suppression of large earthquakes by stress shadows: A comparison of Coulomb and rate‐and‐state failure

Journal of Geophysical Research: Solid Earth, 1998
Stress shadows generated by California's two most recent great earthquakes (1857 Fort Tejon and 1906 San Francisco) substantially modified 19th and 20th century earthquake history in the Los Angeles basin and in the San Francisco Bay area. Simple Coulomb failure calculations, which assume that earthquakes can be modeled as static dislocations in an ...

Erratum to Dynamic Stresses, Coulomb Failure, and Remote Triggering

Bulletin of the Seismological Society of America, 2009
Figure 13h on page 84 in Hill (2008) illustrating the triggering potential of Rayleigh waves with strike-normal incidence on reverse faults at a depth of 10 km is incorrect. The corrected version of Figure 13 is reproduced here. The correction involves exchanging the stress orbits on the left-hand side of the Mohr’s circle in Figure 13h with those on ...

The Tidal Coulomb Failure Stresses on Various Kinds of Seismic Fault

Chinese Journal of Geophysics, 2011
AbstractThe tidal Coulomb failure stresses (TCFS) on various kinds of seismic faults are calculated and their latitudinal variation characters are studied. We compute tidal Coulomb failure stresses at shock‐occurring times on 20395 earthquake faults and analyze the latitudinal distribution of various kinds of real seismic faults that are slip ...

A study of the behaviour of brittle rocks subjected to confined stress based on the Mohr–Coulomb failure criterion

Geomechanics and Geoengineering, 2014
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.

Update and Test of a Seismicity Simulation Program Based on the Coulomb-Navier Failure Criterion and the Stress Transfer Mechanism

Pure and Applied Geophysics, 2019
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, 2012
Summary 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 ...

IC MAGE Model 10 - Mohr-Coulomb failure criterion with stress-dependent elastic stiffness and independent random parameter distributions

2022
IC MAGE M10 is a user-defined model for PLAXIS built using the IC MAGE UMIP framework in which a stress-dependent elastic response is combined with a Mohr-Coulomb failure criterion. Both the stiffness parameters and the strength parameters are determined following independent random distributions.

Dynamic Stresses, Coulomb Failure, and Remote Triggering and to Surface-Wave Potential for Triggering Tectonic (Nonvolcanic) Tremor

Bulletin of the Seismological Society of America, 2012
Hill (2008) and Hill (2010) contain two technical errors: (1) a missing factor of 2 for computed Love‐wave amplitudes, and (2) a sign error in the off‐diagonal elements in the Euler rotation matrix. Correction 1 : The equations for Love‐wave stresses (equation 21 in Hill, 2008, and equation A8 in Hill, 2010), are correct.

Changes in Frequency of Moderate-Size Earthquakes and Coulomb Failure Stress before and after the Landers, California, Earthquake of 1992

Bulletin of the Seismological Society of America, 2001
Changes in the frequency of moderate-size events before and after the 28 June 1992 Landers earthquake are investigated, and their implications are discussed in the context of Coulomb failure stress (CFS) evolution since 1812 in southern California. We systematically considered circular regions and equal-area annuli centered on the epicenter of the ...
