Propagation of Coulomb stress uncertainties in physics‐based aftershock models [PDF]
Journal of Geophysical Research: Solid Earth, 2014 AbstractStress transfer between earthquakes is recognized as a fundamental mechanism governing aftershock sequences. A common approach to relate stress changes to seismicity rate changes is the rate‐and‐state constitutive law developed by Dieterich: these elements are the foundation of Coulomb‐rate‐and‐state (CRS) models.

Nature Communications, 2019 Scattered earthquake locations in the same region cannot be explained solely by coseismic Coulomb stress on planar faults. Instead, the authors suggest Coulomb pre-stress to influence earthquake locations.

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

Onto what planes should Coulomb stress perturbations be resolved? [PDF]
Journal of Geophysical Research: Solid Earth, 2005 Coulomb stress maps are produced by computing the tensorial stress perturbation due to an earthquake rupture and resolving this tensor onto planes of a particular orientation. It is often assumed that aftershock fault planes are “optimally oriented”; in other words, the regional stress and coseismic stress change are used to compute the orientation of ...

Earthquakes in the Shadows: Why Aftershocks Occur at Surprising Locations
The Seismic Record, 2022 For decades there has been a debate about the relative effects of dynamic versus static stress triggering of aftershocks. According to the static Coulomb stress change hypothesis, aftershocks should not occur in stress shadows—regions where static ...

Kuwait Journal of Science, 2023 The incident of increased seismic activity of the Merapi volcano was initiated by several tectonic earthquake phenomena. Analysis of the mechanism of tectonic earthquakes can be studied based on the combination of static stress on the rock.

Geomatics, Natural Hazards & Risk, 2023 The occurrence of the Ms6.8 Luding earthquake on 5 September 2022 filled the seismic gap in the southeastern segment of the Xianshuihe fault zone and transferred stress to the surrounding faults, which attracted much more attention to the seismic hazard.
