Asacha, Complex volcano in Kamchatka, Russia

Asacha is a complex volcano in the southern part of Kamchatka Peninsula, Russia. Its highest point, the western summit, reaches 1911 metres. The massif consists of three cones of the western group, with the Yellow cone (1870 m) adjoining them from the east, and several lower cones at the foot. A glacial cirque with a lake lies on the western part, and the slope is cut by faults, gorges and barrancos.

Asacha is a complex of volcanoes, not a single cone: three cones form the western group, joined on the east by the Zhelty cone at 1870 m, with several lower cones at the foot. The highest point, 1911 m, lies on the western summit. Fumarolic activity is still observed on the massif, and a glacial cirque holding a lake sits on its western part.

The name Asacha also appears as Assachinskaya sopka, the "hill of Assacha", a form still used in Russian accounts of the massif. The volcano's fumaroles, vents releasing volcanic gas, are the feature most often noted by visitors and volcanologists who reach the western cirque.

The massif lies in southern Kamchatka, with the highest point on the western summit at 1911 m. The western part holds a glacial cirque with a lake, and the slopes are cut by faults, gorges and barrancos. Fumarolic activity is present on the volcano, so plan for loose ground and gas near active vents.

The western summit holds a glacial cirque with a lake, and the massif's slopes are cut by faults, gorges and barrancos. Fumarolic activity is still observed on the volcano, so the highest cone is not entirely dormant.
