On Sunday October 23, 2011 an earthquake with a magnitude of 7.3 at 5 km depth hit the provinces of Van and Bitlis in eastern Turkey, followed by a series of powerful aftershocks of magnitudes up to 5.6. The epicentre was located at 38° 37' 40.80"N, 43° 29' 9.60"E, at the village of Tabanli 19 km north-east of the city of Van between the Van Lake and the Iranian border. Several municipalities around the Van Lake were affected.
The map shows the city of Bitlis (approximately 40,000 inhabitants), located at the south-western side of the Van Lake, and the surrounding region, which was affected by the earthquake. Damaged structures were derived by visually comparing high resolution post-disaster QuickBird-2 satellite imagery, acquired on October 26, 2011 , with pre-disaster QuickBird-2 satellite imagery, acquired on October 02, 2011 .
Due to differing acquisition angles, clouds and haze effects, the analysis provides only a coarse estimation of potentially damaged buildings.
Orthorectified and pansharpened QuickBird imagery (0.6 m spatial resolution), acquired on October 02, 2011 serves as background. Please note that the roads do not represent the entire transportation network.
