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
20936 Nemrut Dagi has a rather spheroidal shape. The results supersede previous observations made by Warner and by Brian A. Skiff, which gave similar results (). According to the surveys carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has an exceptionally high albedo of 0.46 and a diameter of 3.6 kilometers, while the "Collaborative Asteroid Lightcurve Link" assumed a standard albedo for stony asteroids of 0.20, and correspondingly, calculates a much larger diameter of 5.3 kilometers based on an absolute magnitude of 13.8. This minor planet was named after the a dormant volcano Nemrut (Nemrut Dağı)
