Onto what planes should Coulomb stress perturbations be resolved? [PDF]
Journal of Geophysical Research, 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 ...

Regional Coulomb Stress Variations in the North of Hellenic Subduction Zone
11th Congress of the Balkan Geophysical Society, 2021 Summary The East Mediterranean region is located in the Alpine-Himalayan orogenic belt and is surrounded by many active tectonic units. ln this study, the stress change is investigated by the Coulomb stress analysis for north of Hellenic Subduction zone located in East Mediterranean.

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 ...

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.
