Klyuchevsky volcano news & activity updates

Klyuchevskoy volcano (Kamchatka): increasing activity

Wednesday Mar 18, 2015 08:11 AM | BY: T

Degassing plume from Klyuchevskoy this morning (KVERT)
Degassing plume from Klyuchevskoy this morning (KVERT)
Mild activity is again occurring at the summit vent of the tall stratovolcano. Aviation color code is orange.
KVERT reports that the "moderate explosive eruption of the volcano continues: gas-steam plumes containing small amount of ash are observing. Satellite data showed: ash plumes rose up to 5 km a.s.l. and drifted about 90 km to the north-east and east of the volcano; a weak thermal anomaly was noted over the volcano."

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.
