Modified Mohr-Coulomb Theory for Triaxial State of Stress
Applied Mechanics and Materials, 2015The 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 ...

Fault Interaction in Alaska: Static Coulomb Stress Transfer
2013Between 1938 and 2002, most ofthe known major active fault segments in southern Alaska with estimated recurrence intervals of less than 700 years have ruptured. Static (coseismic) Coulomb stress transfer has been modeled from the nine largest (M ≥ 7.5) of these earthquakes. Stresses transferred from these sources, ranging from less than 0.001 MPa (0.01

Consistent Regularization of Induced Coulomb Stresses in Displaced Faults
2023This 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.

The Stress Triggering of Aftershocks by Badong M5.1 Mainshock from Coulomb Stress Changes
Advanced Materials Research, 2014TheCoulomb 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.

Erratum to Dynamic Stresses, Coulomb Failure, and Remote Triggering
Bulletin of the Seismological Society of America, 2009Figure 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 ...

COULOMB STRESS ANALYSIS OF KOCAELİ AND SURROUNDINGS
201817 August 1999, Mw = 7.6 Kocaeli Earthquake, revealed the possibility of producing a great earthquake in the North Anatolian Fault extending into the Marmara Sea and the importance of the Earthquake Risk and Seismic Hazard Analysis for the Kocaeli city and all Marmara Region.

Particular Stress Distributions in Granular Wedges under Coulomb Friction Inequality
AIP Conference Proceedings, 2010Constitutive relation governs the performance of stress distribution prediction in granular heaps. However, there is no unique closure of stress relation which can generally characterize the pattern of weight transmission. Under the rigorous theory of continuum mechanics, this study proposes the generalized formulation of admissible stress field ...

Scaling of Fluid-induced Seismicity by Coulomb Stress Transfer Model
72nd EAGE Conference and Exhibition incorporating SPE EUROPEC 2010, 2010The borehole fluid injection is commonly used for CO2 storage and during stimulation of hydrocarbon and geothermal reservoirs. Usually this process induces micro-earthquakes with magnitude up to 4. The spatio-temporal distribution of the induced seismicity can be used for monitoring of fluid movement in the reservoir (passive seismicity) and for ...

Earthquakes and Coulomb stress evolution in a diffuse plate boundary
2016Diffuse plate boundaries are characterized by deformation distributed over a wide area in a complex network of active faults, and by low strain rates. These characteristics make it difficult to understand the spatial and temporal distribution of seismicity. The northern Basin and Range Province (BRP) in the western United States is an excellent example
