Nemrut (volcano) of Lake Van, which is near the volcano, allowed clarification of the chronology and activity of recent eruptions. The potential activity of Nemrut and the close proximity of several Turkish cities inspired recent in-depth studies. In October 2003, the first in Turkey real-time seismic network of sensors has been installed around the volcano. During the first three years of operation the network has registered 133 seismic events with a magnitude of 1.3–4.0. Eruptions of Nemrut were mainly of Plinian type. Their products are mainly alkaline and include a wide range of lavas: from basalt to rhyolite and phonolite, as well
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.
