Büyük Menderes Graben

The Büyük Menderes Graben is an active rift basin in western Turkey, part of the Western Anatolian Extension Zone.[1] It is about 140 km long and 2.5–14 km wide with a west-east trend.[2] It was formed during the early Miocene and remains active, as shown by historical earthquakes, the largest of which was the M7.5 1653 East Smyrna earthquake.[1] It forms a rift valley, through which the Büyük Menderes River drains into the Aegean Sea.
