summit elevation 3253 m
Hasan Dagi is a twin peaked volcano located 230 km SW of Ankara in central Turkey. The summit contains a 5 km wide caldera.
Two terminal cones Big Mt. Hasan (3253 m) and Small Mt. Hasan (3069 m).
Neolithic paintings show caldera formation in 7600-7500 BC. More recent paintings show pyroclastic flows that destroyed towns and villages in 620 BC.
Eruptions have produced lava flows, lava domes, and pyroclastic rocks. The total volume of erupted products is 354 cubic km, and covers an area of 760 sq km.
The volcano contains weak fumarolic activity at the summit, and there is local melting of snow in winter. This indicates that Hasan Dagi is still a potentially active volcano.
