Aftershocks in Stress Shadows are Inconsistent with Modeled Static Coulomb Stress Changes

open access: yesSeismica
Aftershock 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.

COULOMB STRESS CHANGES DUE TO RECENT ACEH EARTHQUAKES

open access: yesJurnal 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

No Significant Effect of Coulomb Stress on the Gutenberg-Richter Law after the Landers Earthquake. [PDF]

open access: yesSci Rep, 2020
AbstractCoulomb-stress theory has been used for years in seismology to understand how earthquakes trigger each other. Whenever an earthquake occurs, the stress field changes, and places with positive increases are brought closer to failure. Earthquake models that relate earthquake rates and Coulomb stress after a main event, such as the rate-and-state ...

Is Coulomb stress the best choice for aftershock forecasting? [PDF]

open access: yesJournal 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

open access: yesJournal 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.

Study on Coulomb Stress Evolution Along Altyn Fault [PDF]

open access: yesE3S 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.

Seismicity and influence of coulomb stress on the risk of earthquakes in South Sulawesi [PDF]

open access: yesJournal of Physics: Conference Series, 2022
Abstract This study aims to analyze the distribution of earthquake events, analyze seismicity based on the parameters of b value, analyze changes in Coulomb stress and analyze the risk of earthquake events in South Sulawesi based on seismicity levels and changes in Coulomb stress in the range of 1991-2021.

The coulomb stress changes for correlation analysis of tectonic earthquake activity and volcanic of the 2001–2010 Merapi eruption based on focal mechanism data

open access: yesKuwait 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.

Global Induced Stress Field From Large Earthquakes Since 1900 and Chained Earthquake Occurrence

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Megathrust earthquake occurrence is dependent on the physical properties and stress environments of convergent plate boundaries. Local and regional earthquakes may modulate the stress environment fractionally that affects the nucleation of next ...

Coulomb pre-stress and fault bends are ignored yet vital factors for earthquake triggering and hazard

open access: yesNature 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.
