PETRINJA EARTHQUAKE AFTERSHOCKS – LOCATIONS, FOCAL MECHANISMS AND RELATED COULOMB STRESS CHANGE
2nd Croatian Conference on Earthquake Engineering ‒ 2CroCEE, 2023Almost 14000 aftershocks have been located in the first six month after the Mw 6.4 Petrinja earthquake of 29 December 2020. Most epicentres lie close to the NW–SE striking right-lateral causative fault, but considerable activity has been recorded in the surrounding area up to about 50 km away.

Complete Coulomb failure stress changes and stress triggering of Yunnan Longlingearthquake sequence
Chinese Journal of Geophysics, 2007The complete Coulomb failure stress changes caused by the 1976 Ms73, Ms74 Yunnan Longling double main earthquakes are calculated. And dynamic and static stress triggering effects on the after earthquake sequence are studied. The results show that the second main earthquake is subjected to the triggering effect of dynamic and static Coulomb ...

Effect of Earth Models on Coulomb Stress Change Caused by Surface Load
Pure and Applied Geophysics, 2021Based on the elastic spherical Earth models, this study presents the radial Love numbers and Green’s functions of the surface load problem, then evaluates the effect of different Earth models on the Coulomb stress changes due to elastic deformation by surface load. First of all, the radial load Love numbers are introduced and verified by comparing them

Coulomb stress changes: From earthquakes to underground excavation failures
International Journal of Rock Mechanics and Mining Sciences, 2009Abstract Evidence from shallow tunnels and mines indicates that, in certain cases, deformation and failure are not confined to the vicinity of the excavation front, as is widely believed. This situation has recently been described as lateral strain propagation from a “source” to remote parts of the excavation through low-strength rocks.

Changes of Coulomb Failure Stress during Stimulation
Proceedings, 2011For the prediction of future reservoir performance, knowledge of the spatio-temporal evolution of the geothermal reservoir in response to stimulation and production is a key issue. During the project for developing an Enhanced Geothermal System at Soultz-

Seasonal stress inversion trends and Coulomb stress changes of RTS in Song Tranh2 reservoir, Vietnam
2022<p>The Song Tranh 2 hydropower construction is located in the Quang Nam province (central Vietnam), it has a reservoir volume of 740 million cubic meters of water and a dam height of 96 m. The reservoir was filled to capacity for the first time in February 2011. The seismicity in the vicinity of reservoir is example of reservoir triggered

Tectonophysics, 2020
Abstract The 26 December 2003 (Mw 6.6) Bam earthquake is one of the most destructive events in the recorded history of Iran. Good variable-slip fault models and precise aftershock data enabled us to calculate Coulomb stress changes on the surrounding faults, optimally oriented faults, and the aftershock nodal planes to learn whether they were brought

The Stress Triggering of Aftershocks by Badong M5.1 Mainshock from Coulomb Stress Changes
Advanced Materials Research, 2014TheCoulomb stress changes are usually adopted to make analysis on faultinteractions and stress triggering. This paper mainly deals with Coulomb stresschange of mainshock and affect on aftershocks. We preliminarily conclude thatthe mainshock produce Coulomb stress change on aftershocks most behavingpositive and triggered them.

Coulomb stress changes in Hesperia Planum, Mars, reveal regional thrust fault reactivation
Journal of Geophysical Research: Planets, 2005The orthogonal pattern of NE and NW striking wrinkle ridges in Hesperia Planum makes this area unique and enigmatic. The wrinkle ridge morphologies revealed in Mars Orbiter Laser Altimeter topography across ridge structures in Hesperia Planum suggest that wrinkle ridges form above thrust faults.

Coulomb stress changes and its correlation with aftershocks of recent Iranian reverse earthquakes
Arabian Journal of Geosciences, 2014In order to investigate the possibility of forecasting aftershock distribution of the Iranian earthquakes, three strong earthquakes from the past 10 years were selected to calculate Coulomb stress changes and its correlation with the aftershock distribution. The common point of these earthquakes is their reverse focal mechanisms.
