Hasan Dagi
"The massive double-peaked stratovolcano Hasan Dagi in Central Anatolia has undergone four episodes of caldera collapse, the latest of which formed a 4-5 km wide caldera at the summit. The modern edifice is the youngest of four major basaltic-to-rhyolitic volcanic complexes dating back to the mid Miocene and was constructed within the latest caldera. Andesitic-to-dacitic lava domes form the two principal summits, of which the westernmost is the highest and is capped by two nested craters. Lava domes and associated pyroclastic-flow deposits blanket more than half the flanks of the Mount Hasan volcanic complex. A group of more than 25 Quaternary cinder cones, maars, and lava flows dot the plains surrounding Hasan Dagi. Interpretations of neolithic paintings representing eruptions from Hasan Dagi are controversial, but geologic evidence supports eruptive activity continuing into the Holocene."  -Smithsonian Volcano Archive
