Nemrut (volcano) the region. The collision of these plates began in the Middle Eocene and closed the stretch of water, which in the Mesozoic formed the Tethys Ocean. Nemrut, along with three other extinct volcanoes of eastern Turkey: Ararat, Tendürek and Süphan, is located in the area of a complex fault, which runs along the boundary of the Arabian and Eurasian plates in the territory of the Armenian Highland. It is the westernmost of these volcanoes, the only one that remains active, and generally the only volcano in Anatolia, which erupted in the historical period. Nemrut is located 10 km north of
Nemrut (volcano) The direction of pressure coming from the Arabian plate is gradually turning from South-North to the West-East, with a linear shift of 7.8–9 mm per year. Fumarolic activity and the presence of many hot springs are observed at the bottom of the caldera. The volcano has an elliptical shape and covers 486 km. Its center contains 377.5 km of volcanic material, mainly 0.23–1.18 million years old lava. Nemrut has a distinct caldera with an area of 46.7 km and a volume of 32.9 km; the maximum height of the edge of the caldera is above sea level (Sivritepe, on the
