Earthquakes form distinctive group

On the basis of waveform features and locations, earthquakes in the vicinity of the volcano during November were identified as constituting a separate group. Since September 1998 more than 20 events with magnitudes ranging from 0.5 to 1.0 occurred at shallow depths (<5 km).

Glacier surge

The volcano's 17-km-long Bilchenok Glacier has begun to advance. The glacier, located in Plosky's caldera, has three large ice cascades on its NW flank. Previous surges of this glacier occurred in 1959, 1976, and 1977. Photo reconaissance flights over Kamchatkan glaciers 10-11 March revealed that Bilchenok's front was 1 km from its 1980 position and 500 m from the 1959 maximum surge. Its surface was broken into blocks, and rupture disturbances of the snow cover were observed.

Photo Gallery

This photo looks north along the cluster of large edifices forming the Klyuchevskaya volcano group. Udina (foreground) and Zimina (middle right) are Holocene cones. Kamen (top center) and Klyuchevskoy (top right) are the far-background. Ushkovsky volcano (top left) lies at the NW end of the volcanic group. Bezymianny is hidden below clouds beside Kamen.

Four volcanoes of the Klyuchevskaya volcano group are visible in this north-looking view. A gas plume emanates from the summit of Bezymianny in the foreground, which is dwarfed by Kamen behind it. Klyuchevskoy is to the upper right, and Ushkovsky is on the left horizon. Krestovsky forms the rounded summit and the glacier-covered Ushkovsky caldera is visible to the far-left.

An ash plume erupts from the summit of Klyuchevskoy on 16 February 1987. Long-term activity includes both explosive and effusive activity from summit and flank vents. This view from the south shows Bezymianny producing a small plume at the lower left, Kamen at the left center, and the broader Ushkovsky on the left horizon.

An ash plume from Klyuchevskoy in 1979 is dispersed in front of the sun in this view looking from the SW. This was part of a dominantly explosive eruption that took place from August 1977 until 1980. The eruption concluded with explosive activity and lava effusion from a flank vent during 5-12 March 1980. Ushkovsky is to the right, with the small Sredny cone in the center.

Clouds drape the margins of the glacier-covered summit caldera of Ushkovsky (Plosky) volcano in the foreground. Two of the highest volcanoes in Kamchatka, Klyuchevskoy (left) and Kamen (right) rise above the layer of clouds to the SE. A small ash plume drifts above the summit of Klyuchevskoy, one of Kamchatka's most active volcanoes.

Ushkovsky is a large compound volcanic massif located at the NW end of the Klyuchevskaya volcano group. Seen here from the NW, it consists of the flat-topped Ushkovsky (far right), which is capped by an ice-filled 4.5 x 5.5 km caldera, and the adjacent higher Krestovsky peak (center). Numerous scoria cones have formed on its flanks.

Kamen (left), Klyuchevskoy (right), and the broad snow-capped Ushkovsky behind them to the west, form the northern end of the Klyuchevskaya volcano group. Ushkovsky consists of the flat-topped Ushkovsky volcano on the left, which is capped by an ice-filled 4.5 x 5.5 km caldera, and the adjacent slightly higher Krestovsky peak on the right.

Symmetrical Klyuchevskoy and the eroded Ushkovsky edifice are seen here SW of the town of Klyuchi. The small Sredny cone, constructed on the eastern flank of Ushkovsky, occupies the saddle between them. Klyuchevskoy is one of Kamchatka's most active volcanoes and Ushkovsky has also erupted in historical time.
