Abstract:
An extrusive-explosive, mainly Strombolian eruption occurred in the crater of Klyuchevskoi Volcano on September 7 - October 2, 1994. The eruption grew more violent and changed to a kind of subplinian activity during the closing phase. The volume of the erupted material was 0.02-0.04 km3 of lava and 0.05 km3 of ash. Its composition was high-Al basalt, typcial of all Klyuchevskoi eruptions. This paper is based on the results of studies that were carried out by a team of volcanologists from the Institute of Volcanology, the workers of the Kamchatkan Volcanological Station, and the seismologists from the Experimental Seismological Team of the Geophysical Survey of the Russian Academy of Sciences.
