Typical eruption style:Dominantly explosive, strombolian and vulcanian activity, sometimes lava flows from fissure vents. At present in a phase of near-persistant activity.

Klyuchevskoy volcano (Kamchatka): continuing lava flow on SE flank
Sat, 4 Jun 2016, 16:53 16:53 PM | BY: T  The lava flow of Klyuchevskoy volcano on 2 June 2016 (KVERT webcam) The two-branches of the lava flow on 2 June (RAS webcam via Culture Volcan)  Heat signal from Klyuchevskoy volcano (MIROVA)
The effusion of a lava flow on the southeastern flank of the volcano continues with little changes. A second flow branch has recently made its appearance.
For now, no significant explosive activity is present, although this could of course change quickly (as often has in the past). A strong thermal signal is visible on satellite data.
Previous news
As had been previously suggested, the volcano's most recent eruptive phase had become both effusive and explosive: in addition to ash-generating strombolian explosions from the summit vent, a new, but short-lived lava flow appeared during 23 or 24 April and descended approx. 800 m on the south-eastern flank of the volcano (along the Apakhonchich ravine). ... read all
The activity of the volcano has intensified, in particular during the past 24-36 hours. KVERT reported that strong strombolian explosions produced an ash plume that rose to 8-9 km altitude that drifted more than 400 km to the SW. ... read all
The volcano continues to be in mild to moderate strombolian activity. ... read all
According to KVERT new phase of (so far) mild strombolian activity seems to have started at the volcano on around 4 April. read all
Mild strombolian activity and associated ash emissions continue from the summit crater of the volcano. read all
  NASA photo of the eruption of Klyuchevsky volcano on 30 September, 1994, the volcano's largest explosion in 40 years. The large 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.
