摘要：On October 23, 2011, a Mw=7.1 earthquake occurred in the province of Van in eastern Turkey. The earthquake caused extensive damage in the city centers of Van and Erciş, and it caused more than 640 fatalities. In the present study, we calculated Coulomb stress failure changes caused by the 2011 Van earthquake. The stress increases up to 5 bars in a zone that extends northeastwards from the midpoint of the southern shore of Lake Van towards Muradiye. The density of aftershock distributions are high in the stress zone. The November 9, 2011 Edremit earthquake (Mw=5.6), which caused further loss of lives and damage in the earthquake struck area, is not an aftershock, but an independent earthquake triggered by the October 23, 2011 Van earthquake.
