Klyuchevskoy volcano (also spelled Kliuchevsky, Klyuchevskaya) is Kamchatka's highest and one of the world's most active volcanoes.
Klyuchevskoy is located in a remote area of the Kamchatka peninsula. It has a large active crater with frequent strombolian and lava fountain eruptions.
Stratovolcano 4835 m (15,863 ft)

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 activity, lava flow on SE flank
Wednesday Apr 27, 2016 21:23 PM | BY: T
 Klyuchevskoi volcano early morning 28 April 2016
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).
It seems that the lava flow remained active at least until Tue (26 April) according to KVERT's daily reports and images from the local observatory, but seems to have stopped by now; glow is no longer visible on clear webcam imagery from yesterday and today.
A significant, continuous steam plume suggests that mild explosive activity continues.

  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.
