The effusive-explosive eruption of the volcano continues at moderately high levels.
A larger and stronger explosion than the average and usual size of explosions at the volcano occurred yesterday. This event is characterized as vulcanian-type explosion.
Large amount of ash with area of 65x70 km rose 9,842 ft (3,000 m) above the summit crater and extended about 50 km to the south-southeast of the volcano.
The lava flow on the southeast flank along the Apakhonchich chute remains active, currently about 2,000 m long.
According to MIROVA Detection System a very high thermal anomaly (1265 MW) continues to be detected in the satellite images.

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.
