Klyuchevskoy volcano (Central Kamchatka, Russia) - Smithsonian / USGS Weekly Volcanic Activity Report for 18 November-24 November 2020 (Continuing Activity)

KVERT reported that Strombolian activity at Klyuchevskoy continued during 13-20 November and lava advanced down the Apakhonchich drainage on the SE flank. A large, bright thermal anomaly was identified daily in satellite images. During 16-18 November explosions recorded in satellite and video data produced ash plumes that rose as high as 7.5 km (24,600 ft) a.s.l. and drifted 104 km E, SE, and S. ... Read all

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.
