Mount Nemrut, whose round caldera is easily identified near the center of this orthorectified image, is a dormant volcano in Eastern Turkey. It is near Tatvan, a small town in the eastern Anatolian province of Bitlis. The mountain rises from the southwestern shore of Lake Van (upper right), and enters the district of Ahlat to the north.

The volcano is 3,050 m (10,007 ft) high and its elliptic caldera has a diameter of about 7 km by 8 km (4 mi by 5 mi). The western part of the caldera contains a large coldwater crater lake about 155 m (509 ft) deep. There is also a small warm lake whose temperature reaches 60 °C (140 °F), providing evidence of continuing volcanic activity.

Mount Nemrut is the southernmost and youngest of the chain of volcanoes in eastern Anatolia. It is a stratovolcano that began erupting during the fourth geological era and continued to be active until 1597 A.D.

As a result of the volcanic eruptions of Mount Nemrut, the single Van-Mus River Basin was divided into two separate basins. The eruption of Nemrut volcano also led the formation of Lake Van, the largest lake in Turkey.
