Geography & Climate
Qal'eh Hasan Ali is located in Iran, within the Central Asia Volcanic Province of the broader Arabia-Central Asia Volcanic Regions. Situated at 29.38° N, 57.55° E in the Northern Hemisphere, the volcano lies within a subtropical climate zone. At 2,400 meters above sea level, Qal'eh Hasan Ali rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
The Qal'eh Hasan Ali volcanic field in SE Iran contains 14 maars of late Quaternary age, which were erupted through desert alluvium, granodioritic rocks, and Eocene volcanics in an area several hundred kilometers away from the closest Quaternary volcanoes. The maars, which produced tephritic pyroclastic deposits, have diameters ranging from 150 to 1200 m. The largest, known as Great Crater, is 1.2 km wide and 200-300 m deep. Ar-Ar dating of phlogopite in volcanic bomb samples from Great Crater gave ages of 112-119 ka (Pang and others, 2015).
