Changes of coulomb stress and seismicity rate following large earthquakes of the Taiwan area
Speaker: I-Ming, Tai
Abstract
Aftershocks and subsequent main shocks often occur in regions that experienced an increase in Coulomb stress caused by the main shock, and that earthquakes become less prevalent than before the main shock in regions subject to a Coulomb stress drop. In this study, we aim to the Coulomb stress changes affects the correlation between observed changes in the rate of earthquake production. We use the aftershock activity following 1972 M w 6.74 Ruei-Suei earthquake, 1998 M w 5.84 Ruei-Li earthquake and 2010 M w 5.96 Jia-Sian earthquake as the cases study.
