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 the fruitful collaboration of the Palomar and Leiden Observatory in the 1960s and 1970s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of . In December 2015, a rotational lightcurve of "Nemrut Dagi" was obtained by American astronomer Brian Warner at his CS3–Palmer Divide Station () in California. Lightcurve analysis gave a well-defined rotation period of hours with a brightness variation of 0.08 magnitude (), indicating that the body
