Applied Sciences, 2017 The 2016 Ecuador M 7.8 earthquake ruptured the subduction zone boundary between the Nazca plate and the South America plate. This M 7.8 earthquake may have promoted failure in the surrounding crust, where six M ≥ 6 aftershocks occurred following this ...

The Mohr–Coulomb criterion for intact rock strength and friction – a re-evaluation and consideration of failure under polyaxial stresses [PDF]
Solid Earth, 2016 Darley Dale and Pennant sandstones were tested under conditions of both axisymmetric shortening and extension normal to bedding. These are the two extremes of loading under polyaxial stress conditions.

The Generalized Mohr-Coulomb Failure Criterion
Applied Sciences, 2023 With the construction of supertall buildings such as high earth dams, the linear envelope of the Mohr-Coulomb (M-C) failure criterion fitted to lower confined pressure would significantly underestimate the loading capacity of foundations, causing a huge ...

Earth and Planetary Physics, 2023 In this research work, we present the evolution of Coulomb failure stress (CFS) in the Sulaiman Lobe and its implications for seismic hazard assessment. The Chaman transform fault, ~1,000 km long, is the major active fault that marks the western boundary between Pakistan and Afghanistan on the Indian Plate.

Study on Coulomb Stress Triggering of the April 2015 M7.8 Nepal Earthquake Sequence [PDF]
International Journal of Geophysics, 2016 In April 2015, a M7.8 earthquake occurred less than one month before a M7.3 earthquake near Kodari, Nepal. The Nepal earthquake sequences also include four larger (M > 6) aftershocks. To reveal the interrelation between the main shock and the aftershocks,

COULOMB STRESS CHANGES DUE TO RECENT ACEH EARTHQUAKES
Jurnal Penelitian Fisika dan Aplikasinya, 2015 Coulomb stress change analysis has been applied to understand whether the 2013/07/02 (Mw=6.1) has been triggered by 2013/01/21 earthquake (Mw=6.1) the proximity to failure on the Aceh segment of Sumatra Fault Zone (SFZ). We examine the problem of how one

Mohr-Coulomb Failure Condition and the Direct Shear Test Revisited [PDF]
Acta Polytechnica, 2004 An alternative critical plane orientation is proposed in the Mohr-Coulomb failure criterion for soils with an extreme property. Parameter identification from the direct shear test is extended to incude the lateral normal stress.

Spatiotemporal Evolution of Pore Pressure Changes and Coulomb Failure Stress in a Poroelastic Medium for Different Faulting Regimes [PDF]
Earth and Space Science, 2021 Abstract Spatial distribution of aftershocks has been explained by the co‐seismic static Coulomb Failure Stress changes (ΔCFS) to some extent. In practice, the earth's crust is porous medium saturated with fluid filling pores, cavities, cracks, and faults.

Stress‐field rotation and rooted detachment faults: A Coulomb failure analysis [PDF]
Journal of Geophysical Research: Solid Earth, 1997 Several well‐known mechanical models have shown that unusual boundary or loading conditions can alter principal‐stress orientations into configurations consistent with low‐angle normal faulting. Such models, however, have not demonstrated whether magnitudes of reoriented stresses are sufficient to initiate and promote slip on low‐angle surfaces.
