Coseismic Displacement of the Earth Crust Using Permanent GPS Stations in Ahar - Varzeqan Earthquake 2012

In the 11th August 2012 two Earthquakes trembled Azarbayjan that their scales were 6 Mw and 6.2 Mw. The locking depth of these two earthquakes is about 10 km, the epicenter of the first one is 38.55 N and 46.87 E, and the second one is 38.87 N and 46.87 E. In this research displacement of the earth crust during trembling on these stations was determined by using permanent GPS stations in Ahar Earthquake 2012. The cosiesmic offset due to the Ahar earthquake has been studied using permanent GPS Network of Azarbayjan (a sub network of Iranian permanent GPS Network). Here, we explore these issues using data processing and times series analysis of the GPS sites. We found 0.5 to 2 cm offset that the GPS site (near and far) showed from the main rapture due to earthquake.
