No significant change in the effusive-explosive activity at the volcano has occurred during the past days.
The flank-to-lateral eruption on the NW slope continues at an altitude of 2,800 m forming the cinder cone around the NW fissure vent.
Near-constant spattering continues to feed the lava flow from the fissure.
Phreatic explosions continue in interaction with snow, ice and lava in the area of Erman glacier generating a gas-steam plumes containing some amount of ash.
A highly elevated surface temperatures were identified in satellite data.
A beautiful video of growing cinder cone was recorded by Artyom Gromov and his team in near distance of this event as can be watched below.

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.
