Fuss Peak is an isolated andesitic stratovolcano on southern Paramushir Island, Kuril Islands. The volcano rises almost 3000 m from the sea floor and forms a peninsula of Paramushir connected to it by a low isthmus. The volcano contains a 700 m wide and 300 m deep crater, with a deep gully cutting its NW rim and forming a canyon down to the coast. Fresh-looking lava flows are on the E and SE flanks. The last confirmed historic activity was in 1854.
