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) The direction of pressure coming from the Arabian plate is gradually turning from South-North to the West-East, with a linear shift of 7.8–9 mm per year. Fumarolic activity and the presence of many hot springs are observed at the bottom of the caldera. The volcano has an elliptical shape and covers 486 km. Its center contains 377.5 km of volcanic material, mainly 0.23–1.18 million years old lava. Nemrut has a distinct caldera with an area of 46.7 km and a volume of 32.9 km; the maximum height of the edge of the caldera is above sea level (Sivritepe, on the
