Klyuchevskoy, Kamchatka : Strong Strombolian activity of the volcano began .

Activity of the volcano increased. Strong Strombolian activity of the volcano began to observing from 1125 UTC on 03 April (a bright incandescence of the summit crater). A bright thermal anomaly over the volcano began continually registering at satellite images from a dark time on 05 April. Strong gas-steam volcanic activity continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time.

A moderate activity of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

The eruption of Klyuchevskoy volcano – a view from IVS FED RAS base “Apakhonchich” on October 15, 2013. Strombolian and Vulcanian activity, large lava flows on the south-western volcanic flank and hot avalanches on the south-eastern flank.

Klyuchevskoy (also spelled 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. It 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 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 the 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.
