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) mantle). More recent studies have confirmed these findings. The seismic activity in the region is high – in recent years there have been several earthquakes directly related to the Nemrut fault. Significant seismic events of the last 150 years that occurred within 30 km of Nemrut include the earthquakes of 18 May 1881 (magnitude 6.7), 29 March 1907 (5), 27 January 1913 (5), 14 February 1915 (6), and 3 November 1997 (5). There is evidence that the nature of volcanism in the region may change due to the shift of stress at the boundary of the Arabian and Eurasian plates.
