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 and 6 months (922 days). Its orbit has an eccentricity of 0.10 and an inclination of 19° with respect to the ecliptic. Due to its perihelion of less than 1.668 AU, "Nemrut Dagi" is classified as a Mars-crosser by the Lightcurve Data Base, while in JPL's data base, which requires a perihelion of less than 1.666 AU, the asteroid is simply an inner main-belt asteroid. The asteroid's observation arc begins 18 years prior to its official discovery observation, with its identification at Palomar Observatory in February 1953. The survey designation "T-1" stands for the first Palomar–Leiden Trojan survey, named after
