Ebeko is one of the most active volcanoes in the Kurile Islands, located in northern Paramushir Island south of Kamchatka.
Ebeko volcano has a flat top with 3 summit craters aligned SSW-NNE. The eastern part of the southern crater contains a large boiling spring. The middle crater has a hot lake with solfataras along its shore. The lower northern crater has a small, cold lake and is separated from the middle crater by a narrow ridge.
Historical activity has been recorded since the late 18th century and consisted in small to moderate explosive eruptions from the summit craters. Intense fumarolic activity occurs in the summit craters of Ebeko and on the outer flanks of the cone, as well as inside lateral explosion craters.
