Klyuchevskoy volcano news and activity updates
The strong explosive activity at Klyuchevskoy continues. Since June 28, the strongest explosions have been generating ash columns to 10 km high and the resulting ash plume is now forming a band of ash streching as far as Alaska. The ash plume is of major concern for aircraft in the area and air traffic in the area needs to be diverted.Read all
Strong explosive and effusive activity at Klyuchevskoy volcano continues. The activity peaked on 29-30 June when near continuous ash emissios produced ash plumes more than 10 km (or 32,000 ft) high that extended up to 300 km to the west and south-west.
KVERT maintains the highest level of alert for Klyuchevskoy.
Kliuchevskoi is Kamchatka's highest and most active volcano. Since its origin about 6000 years ago, the beautifully symmetrical, 4835-m-high basaltic stratovolcano has produced frequent moderate-volume explosive and effusive eruptions without major periods of inactivity. Kliuchevskoi rises above a saddle NE of sharp-peaked Kamen volcano and lies SE of the broad Ushkovsky massif. More than 100 flank eruptions have occurred at Kliuchevskoi during the past roughly 3000 years, with most lateral craters and cones occurring along radial fissures between the unconfined NE-to-SE flanks of the conical volcano between 500 m and 3600 m elevation. The morphology of its 700-m-wide summit crater has been frequently modified by historical eruptions, which have been recorded since the late-17th century. Historical eruptions have originated primarily from the summit crater, but have also included numerous major explosive and effusive eruptions from flank craters.
