Mutnovsky is a periodically active Volcano in southern Kamchatka, about 70 km SW of Petropavlovsk-Kamchatsky. The relative height of the volcano is 1500 m.

Mutnovsky is composed of four overlapping stratovolcanoes and summit craters up to 1.3 km wide. The eastern part contains two volcanoes of the Somma-Vesuvius type. South Mutnovsky volcano is located west of Akhomten volcano and contains a 400 m wide explosion crater. The active crater is located in the northern stratovolcano and is 440 x 100 m wide and 180 m deep.

Verkhneye fumarole field is located in the northwestern part of the crater and covers 3200 sq m. The field contains vents emitting gas with a emission rate up to 160 m/s.
