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
20936 Nemrut Dagi has a rather spheroidal shape. The results supersede previous observations made by Warner and by Brian A. Skiff, which gave similar results (). According to the surveys carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has an exceptionally high albedo of 0.46 and a diameter of 3.6 kilometers, while the "Collaborative Asteroid Lightcurve Link" assumed a standard albedo for stony asteroids of 0.20, and correspondingly, calculates a much larger diameter of 5.3 kilometers based on an absolute magnitude of 13.8. This minor planet was named after the a dormant volcano Nemrut (Nemrut Dağı)
