Van earthquake-stricken area was closed to an active tectonic intersection zone in NW Iran, east of Turkey and SW Caucasus, and the earthquake fault with a compressional mechanism created a surface rupture with a 10km length in the north of Van, between the coast line of Van and Erçek Lake. This article represent the seismological aspects of the Van earthquake based on a 5 days visit by the reconnaissance team of IIEES started in the 26th day after the mainshock. Meanwhile, there will be a look at the "response" of the disaster management system in Turkey to this major earthquake.
