Ebeko

Stratovulcano · Russia · 1103 m

An ash plume rises above the North crater of Ebeko volcano at the northern end of Paramushir Island on 9 September 1989. An explosive eruption that began on 2 February 1989 continued until April 1990. Three summit craters located along a SSW-NNE line form the main edifice at the northern end of a complex consisting of five cones. Activity recorded since the late 18th century has included small-to-moderate explosive eruptions from the summit craters.

Sintesi geologica

The flat-topped summit of the central cone of Ebeko volcano, one of the most active in the Kuril Islands, occupies the northern end of Paramushir Island. Three summit craters located along a SSW-NNE line form Ebeko volcano proper, at the northern end of a complex of five volcanic cones. Blocky lava flows extend west from Ebeko and SE from the neighboring Nezametnyi cone. The eastern part of the southern crater contains strong solfataras and a large boiling spring. The central crater is filled by a lake about 20 m deep whose shores are lined with steaming solfataras; the northern crater lies across a narrow, low barrier from the central crater and contains a small, cold crescentic lake. Historical activity, recorded since the late-18th century, has been restricted to small-to-moderate explosive eruptions from the summit craters. Intense fumarolic activity occurs in the summit craters, on the outer flanks of the cone, and in lateral explosion craters.

Sintesi da Wikipedia

Riassunto in inglese

Ebeko is a highly active somma volcano located on the northern end of Paramushir Island, Kuril Islands, Russia. It is one of the most active volcanoes of the Kuril Islands. Eleven eruptions have been recorded between 1793 and 1991. Most of the eruptions are small (VEI=1) with the exception of the 1859 eruption (VEI=3). Most eruptions were phreatic and explosive.
