Özet

Abstract Turkey's landforms were determined during the period when the Arabian Plate collided with the Anatolian Plate. This process, which started the new tectonic period of the Anatolian plate, took place approximately 12 million years ago, in the period called the middle Miocene. The Anatolian plate is a region that constantly compresses and creates earthquakes. The African plate subducting under the Anatolian plate along the Hellenic-Cyprus arc causes earthquakes in Eastern Anatolia, NAF (North Anatolian fault line), EAF (Eastern Anatolian fault line) and Western Anatolia (Aegean) regions. Another big plate pushing the Anatolian plate is the Arabian plate. The Arabian plate is constantly pushing the Anatolian plate towards the west. The Anatolian plate moves from the southeast to the west of the Arabian plate at a speed of 25 mm/year. The area where Anatolia meets the Arabian plate is the Eastern Anatolian fault line. The 558 km long fault extends from Bingöl Karlıova to the Gulf of İskendurun. Here it merges with the Ölüdeniz fault, which is a continuation of the East African fault line. Fault lines are areas where large earthquakes occur. Due to earthquakes in these regions, cities may be forced to relocate due to the natural and human factors they encounter. Türkiye has been constantly under the influence of earthquakes since ancient times. Therefore, some settlements have been destroyed and some have been displaced due to the effects of earthquakes until today. The Van earthquake, one of the earthquakes in the region, was an earthquake with a magnitude of Mw = 7.2 that affected Van - Erciş and its surroundings on October 23, 2011 at 13:41 local time. The earthquake caused damage in many villages connected to the center, especially in Erciş district, the largest district of Van. The epicenter of the earthquake was approximately 24 km from Van. It is around Tabanlı village (KRDAE) located in the north (38.9N/43.5E).
