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) a diameter of 10–100 m formed outside of the main cone, mainly in its northern part. They include Girigantepe (2433 m), Arizintepe (2445 m), Kayalitepe (2311 m), Mezarliktepe (2409 m), Atlitepe (2281 m), Amis (2166 m), Kevriağa (2087 m), Avuştepe and Sivritepe, which is the highest point of Nemrut. Basaltic lava of these craters are the youngest volcanic rocks within Nemrut. The last eruption took place on 13 April 1692. Since then only bursts of steam were observed at the bottom of the caldera, indicating fumarolic activity. Besides the legendary relationship of the volcano with King Nimrod, in 1990s scientists
