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
