Smithsonian Institution Global Volcanism Network Bulletin v. 19, no. 10, October 1994 Kliuchevskoi (Kamchatka) Fumarolic gas-and-steam plume to 2,500 m; continuous tremor Kliuchevskoi Kamchatka Peninsula, Russia (56.06N, 160.64E) A major eruption on 1-3 October (see Bulletin v. 19, no. 9) generated an ash column to 15-20 km altitude and sent lava bursts 4.5 km high. Activity had decreased by 4 October, and continued to decline the following week. Continuous tremor after 3 October and into early November had a maximum amplitude of 0.23-0.53 fm, registered 11 km from the volcano. On 5 and 7-9 October the volcano was obscured by clouds, but on 6 October the fumarolic plume from the summit crater rose ~600 m above the rim and was directed NE. Observers in Kliuchi (25 km NNE) reported decreased activity during 8-15 October. Gas-and-steam columns rising from two apertures at the summit reached 2,500 m above the crater on 10 October and 800 m on 14 October. Once again during clear weather a gas-and-steam column was seen rising 200 m above the summit crater on 17, 22, and 23 October and to 800-1,500 m on 18-20 October. During 27-29 October the column rose 200-800 m above the summit. The volcano was obscured by clouds from 30 October to 2 November. Information Contact: Same as for Bezymianny.
