Hasan Dağı is a large stratovolcano in Central Anatolia, near the city of Aksaray. The eruptions involving the collapse of the caldera in Hasandağ, where rocks with a composition ranging from basaltic to rhyolitic, summit caldera, double summit, domes, ignimbrites, block and ash flows and debri avalanches constitute today's structure. The two distinctive peaks of Hasandağ are andesitic to dacitic lava domes. Pyroclastic flow deposits from lava domes blanket the flanks, and large caldera-collapse ignimbrites covers in the west, south and northeast of the volcano. Numerous cinder cones and associated lava flows can be found low on the flanks and surrounding plains.
The eruptions around the Hasandağı volcano started about 13 million years ago and have been up to historical times. Today, Hasandağı continues its activity, which also has a fumerol activity of approximately 55ºC at its peak. There are also many gases of volcanic origin around the volcano.
