The activity of the volcano has remained essentially unchanged at moderate levels characterized by effusive-explosive eruption.
A beautiful strombolian activity continues from the summit crater associated with lava spattering with ejecta thrown at an approximate height 300 meters above the crater. Gas-steam plume containing some amount of ash reached 23,000 ft (7,000 m) altitude and extending about 60 km to the east of the volcano.
The lava flow on the southeast flank along the Apakhonchich chute remains active, currently about 2,000 m long.
A satellite image from 8 November shows that elevated surface temperatures in the area of volcanic edifice were observed as MIROVA Detection System detected a very high thermal anomaly (1059 MW-1373 MW) during the past 3 days, likely caused by the lava flow.

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.
