The last recorded eruption of Ebeko volcano was in 1991. Table 2 summarizes activity on Ebeko from February-April 2004 as reported by observers Leonid and Tatiana Kotenko (observations made on days when clouds did not obscure the volcano).

On 14 April 2004 a fishing craft reported a white gas plume emerging from Tatarinov volcano. That volcano lies near the opposite (southern) end of Paramushir Island. The plume came from Tatarinov's fumarolic field and remained at low altitude following the Tukharka river. Also in the southern part of Paramushir island, the volcanoes Chikurachki (last active 17-18 April 2003, SEAN 28:07) and Fuss Peak (SEAN 12:04) were both reported quiet.

Geologic Background. 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.
