THE 1985 ERUPTION OF BEZYMIANNYI

Abstract

The 1985 eruption of Bezymyannyi has been the largest event since the 1956 catastrophic eruption. A directed blast destroyed part of the volcanic dome and deposited specific pyroclastic material. A series of pyroclastic flows moved downslope. The products of eruption have been examined in detail and classified into several genetic types. Although the eruption of 1985 was much weaker than that of 1956, it resembled the latter in activity.
