Tidal Coulomb Failure Stresses in the northern Andean intermediate depth seismic clusters: Implications for a possible correlation between tides and seismicity [PDF]
Tectonophysics, 2019 A recent statistical analysis of the relationship between tides and seismic activity in Colombia has suggested the existence of correlation anomalies for the case of intermediate depth events in the Bucaramanga nest and the Cauca cluster (Moncayo et al., 2019).

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 ...

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.

What Is Better Than Coulomb Failure Stress? A Ranking of Scalar Static Stress Triggering Mechanisms from 105 Mainshock‐Aftershock Pairs [PDF]
Geophysical Research Letters, 2017 AbstractAftershocks may be triggered by the stresses generated by preceding mainshocks. The temporal frequency and maximum size of aftershocks are well described by the empirical Omori and Bath laws, but spatial patterns are more difficult to forecast. Coulomb failure stress is perhaps the most common criterion invoked to explain spatial distributions ...

Coulomb Failure Stress and triggered seismicity: The consequences of fault zone damage
, 2019 Predictive models for the stress triggering of earthquakes have been built on the concept of Coulomb Failure Stress (CFS). CFS is the change in proximity of a given 'target' fault to the Mohr-Coulomb shear failure criterion due to changes in stress induced by slip on a neighbouring 'source' fault.

Coseismic Surface deformation and Coulomb Static Failure Stresses change Modeling of 2024 Mw 7 Uqturpan earthquake, China [PDF]
Abstract Knowledge of the earthquakes along the active tectonic structure is fundamental to comprehend the mechanics of continental plates margins and to approximate the earthquake potential in tectonic settings of area of interest. On 22nd January, 2024, an earthquake with magnitude Mw 7 struck in the area located 136 km west of Aksu, China ...

SeismicaMost earthquake energy release arises during fault slip many kilometers below the Earth’s surface. Understanding earthquakes and their hazard requires mapping the geometry and distribution of this slip. Such finite-fault maps are typically derived from surface phenomena, such as seismic and geodetic ground motions.
