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

Aftershocks in Stress Shadows are Inconsistent with Modeled Static Coulomb Stress Changes
SeismicaAftershock triggering is commonly attributed to increases in static Coulomb stress. In some areas, termed "stress shadows", a decrease in Coulomb stress is predicted to suppress earthquake occurrence.

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.

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.

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.

Aftershock triggering by complete Coulomb stress changes [PDF]
Journal of Geophysical Research: Solid Earth, 2002 We examine the correlation between seismicity rate change following the 1992, M7.3, Landers, California, earthquake and characteristics of the complete Coulomb failure stress (CFS) changes (ΔCFS(t)) that this earthquake generated. At close distances the time‐varying “dynamic” portion of the stress change depends on how the rupture develops temporally ...

Near‐prospective test of Coulomb stress triggering [PDF]
Journal of Geophysical Research: Solid Earth, 2014 AbstractNumerous studies retrospectively observed a strong association between earthquake location and increased static Coulomb stress. In addition to confirming these results for southern California seismicity, we observed prospective forecasting potential in static stress evolution.

A Coulomb Stress response model for time-dependent earthquake forecasts
Journal of Geophysical Research: Solid Earth, 2022 AbstractSeismicity 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.

Study on Coulomb Stress Evolution Along Altyn Fault [PDF]
E3S Web of Conferences, 2020 Taking the altyn fault zone as the study area, the maxwell layered viscoelastic medium model and the PSGRN / PSCMP program were used to study the evolution of the cumulative coulomb stress over the altyn fault from 1900 to 2020, analyze the future seismic hazards of faults in the altyn fault zone.
