The strong explosive activity at Klyuchevskoy continues. Since June 28, the strongest explosions have been generating ash columns to 10 km high and the resulting ash plume is now forming a band of ash streching as far as Alaska. The ash plume is of major concern for aircraft in the area and air traffic in the area needs to be diverted.

Strong explosive and effusive activity at Klyuchevskoy volcano continues. The activity peaked on 29-30 June when near continuous ash emissios produced ash plumes more than 10 km (or 32,000 ft) high that extended up to 300 km  to the west and south-west. 
KVERT maintains the highest level of alert for Klyuchevskoy.

Kliuchevskoi continues to be active above background levels. Video and visual observations during 1-4 June show strombolian and vulcanian eruptions at the summit crater, as well as lava flows generating steam explosions where hot lava interacts with ice on the NW and SE flanks. Ash plumes rose to altitudes of 7 km (23,000 ft) a.s.l. and drifted E and SE during 1-6 June. Plumes were seen on satellite imagery drifting E and S during 1-8 June. Based on information from KVERT, the Tokyo VAAC reported that an ash plume rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted NW on 12 June.

The explosive-effusive eruption of Klyuchevsy volcano continues and the alert level has been raised to red. Ash explosions more than 10 km (32,800 ft.) ASL could occur at any time. The activity of the volcano could affect international and local aircraft.
The amplitude of volcanic tremor has increased during last few days. According to visual data from Kozyrevsk and Klyuchy, an ash plume from the central crater about 9700 m (31900 ft) ASL was observed at 03:50 UTC on May 16 extending to the North. According to satellite data, ash plumes extended for 200-600 km (125-370 mi) to the north-east, north-west, and east from the volcano this week. A large thermal anomaly was noted all days.

Based on observation and video data, lava from Kliuchevskoi flowed down the NW flank on 29 March. On 31 March, lava bombs from Strombolian activity were projected about 100-200 m above the crater. According to a news article, lava flows are interacting with snow and ice and producing vapor plumes.

Mild strombolian activity continues at Klyuchevsky volcano. Over the past weeks, explosions were observed throwing lava bombs about 50-100 m above the crater.

Weak explosive activity at Klyuchevsky began on February 15. Strombolian activity ejecting lava bombs up to 50-100 m above the crater were observed on February 16-18. According to the satellite data from Russia and USA, a thermal anomaly in the area of the terminal crater was observed.

Kamchatka's Klyuchevskoi volcano started erupting Thursday Feb. 16. KVERT reports increased seismicity and visible strong strombolian / vulcanian activity, producing jets of incandescent material to 300 m above the crater and ash plumes to an altitude of 5-6 km.

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.
