Turkey is located on one of the world's most active seismic Alpide Belt which is an orogenic and seismic belt that includes a series of mountain ranges.

Seismicity in Turkey


a)The North Anatolian Fault Zone: North Anatolian fault zone extending in an east-west direction in the northern part of Turkey has a length of about 1,500 km. In the Marmara Region; starting from the Saros Gulf, it stretches as far as the Aras Valley in Eastern Anatolia.

b)The Southeastern Anatolian Fault Zone: extends from the Iskenderun to the east of Van. It includes; Hatay, Kahramanmaraş, Adıyaman, Malatya, Elazığ, Bitlis and Van.

c) The Western Anatolian Fault Zone: There are several active fault lines extending along the plains of Bakırçay, Gediz, Küçük and Büyük Menderes in the Aegean Region. This earthquake zone includes Ayvalık, Dikili, İzmir, Aydin, Denizli, Isparta and Akşehir.
