Klyuchevsky volcano news & activity updates

Klyuchevskoy volcano (Kamchatka): eruption has ended, alert level lowered

Thursday Jan 02, 2014 15:52 PM | BY: T

The explosive-effusive eruption of the volcano finished on December 20, according to KVERT who placed the Aviation Color Code back to green today.
Since that date, the volcano has only produced its normally strong steam/degassing plume. Satellite images still show a thermal anomaly from the now cooling lava flows. Seismic activity continues at low levels. KVERT interprets some of these data that the magma column has descended and probably left a deep crater at the summit.

Saturday, Dec 07, 2013
A phase of strong explosive activity occurred last evening (this morning Kamchatka time), generating a dense ash plume that rose to approx. 20,000 ft (6 km) altitude and drifted 400 km to the east. This is the strongest activity since 20 November this year, when a powerful paroxysmal phase with lava fountains, lava flows and strong ash emissions ended. During today, the volcano seems to have calmed down again. ... [more]

Background:

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.
