Evaluating models of Coulomb stress transfer: Is variable fault geometry important? [PDF]
Geophysical Research Letters, 2016 To determine the importance of receiver fault geometry in Coulomb stress calculations a new methodology is presented to model faults with variable geometry. Although most models use planar faults, it is known that these are inaccurate representations of faults observed in the field. The central Italian Apennines are chosen as a straightforward tectonic

Coulomb Stress Change in Ahar-Varzaghan (20121108) Earth Quakes [PDF]
, 2021 Abstract Understanding how the movement of faults and deformation affects such as motion-induced surface stress and strain, which is very important in seismic regions. The best way to learn about the effects of fault movement is modeled. For example, the modeling of surface displacement or deformation and the amount of damage earthquake can be ...

Range estimation of horizontal stress of deep rock based on Mohr-Coulomb criterion
Results in Physics, 2019 In-situ stress estimation is of great significance in deep coal mining. The vertical stress of the underground rock mass is generally estimated by the product of the upper cover average specific gravity and its depth, and it is difficult to estimate the ...

Application of the Modified Mohr–Coulomb Yield Criterion in Seismic Numerical Simulation of Tunnels
Shock and Vibration, 2021 To solve the classical problem that the Mohr–Coulomb yield criterion overestimates the tensile properties of geotechnical materials, a modified Mohr–Coulomb yield criterion that includes both maximum tensile stress theory and smooth processing was ...

Importance of forearc topography for the triggering of aftershocks of megathrust earthquakes: insights from mechanical models and the Tohoku-Oki and Maule earthquakes [PDF]
Solid EarthAftershocks of megathrust earthquakes at subduction zones may be driven by stresses arising from the topography of the forearc. However, the effect of topographic stresses on aftershock triggering is quantitatively not well understood and has been ...

Stress loading history of earthquake faults influenced by fault/shear zone geometry and Coulomb pre-stress [PDF]
Scientific Reports, 2020 AbstractWhether the stress-loading of faults to failure in earthquakes appears to be random or to an extent explainable, given constraints on fault/shear-zone interaction and the build-up and release of stress over many earthquake cycles, is a key question for seismic hazard assessment.
