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) as pyroclastic emissions and slag. Eruption of different periods were either effused or explosive. Nemrut is located on a fault that crosses the volcano from the north to the south and contains the main crater and a number of small craters, maars, hot springs and fumaroles. The volcanic activity of Nemrut occurred in three stages: the formation of a cone (pre-caldera stage), the post-caldera stage, and the late stage. Further, divisions are debatable and are based on different interpretations of the stratigraphic data. The formation of Nemrut and the first stage of eruptions began about 1 million years ago with
