Is Coulomb stress the best choice for aftershock forecasting? [PDF]
Journal of Geophysical Research: Solid Earth, 2020 <p>The Coulomb failure stress (CFS) criterion is the most commonly used method for predicting spatial distributions of aftershocks following large earthquakes. However, large uncertainties are always associated with the calculation of Coulomb stress change.

A Coulomb Stress response model for time-dependent earthquake forecasts
Journal of Geophysical Research: Solid Earth, 2022 Seismicity models are probabilistic forecasts of earthquake rates to support seismic hazard assessment. Physics-based models allow extrapolating previously unsampled parameter ranges and enable conclusions on underlying tectonic or human-induced processes.

Coulomb stress changes and magnitude-frequency distribution for Lake Van region
Bulletin of the Mineral Research and Exploration, 2022 The tectonic structure of Türkiye is under the influence of Arabian, Eurasian, African, and Anatolian plates. Lake Van region, located in eastern Türkiye, has been exposed to many devastating earthquakes in historical and instrumental periods.

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 ...

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,

Earthquake Growth Inhibited at Higher Coulomb Stress Change Rate at Groningen
Geophysical Research LettersGas extraction from the Groningen gas field resulted in significant induced seismicity. We analyze the magnitude‐frequency distribution of these earthquakes in space, time and in view of stress changes calculated based on gas production and reservoir ...

Analysis of Seismicity Level and Coulomb Stress Changes in the Central Sulawesi Region in 1996-2022
Jurnal Fisika Flux, 2023 Central Sulawesi is an area that is prone to earthquakes. The movement of the Palu Koro Fault is the trigger for most of the destructive earthquakes in the Central Sulawesi region.

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 ...
