The caldera of Nemrut Dağ is one of the volcanoes near Van lake. It is one of the volcanoes that erupted in historic times.

Introduction:

The diameter of the caldera is about 9 x 5 km and it is half filled by a crater lake. There happend post calderic volcanism, producing rhyolithic & basaltic material at the caldera rim and on its floor. Pyroclastic flows and the emission of glassy obsidian lava flows accompanied construction of lava domes within the caldera; later activity formed a series of cinder cones and lava domes erupted along N-S-trending fissures on the northern flank. The most recent activity has been concentrated along a NNW-trending fissure cutting the eastern caldera floor and extending beyond the north caldera rim; nearly two dozen cinder cones and lava domes were constructed on the caldera floor. Ash layers in Lake Van document numerous Holocene eruptions, and an historical eruption in 1441 AD from a north-flank fissure involved compositionally bimodal lava flows.
