Klyuchevskoy volcano (Kamchatka): strombolian activity increases, strong ash emissions and possible lava flow

Klyuchevskoi volcano this morning with what is likely a new lava flow (KVERT webcam)
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.
Webcam images have been mostly unclear, but view from this evening (dawn in Kamchatka) suggest that a new lava flow might have started to descend the volcano's flanks, which would be a typical occurrence if the magma supply rate has indeed increased. An intense thermal anomaly is being recorded on satellite data as well.
KVERT alerted this morning that the "explosive eruption 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 aviation color code was raised to ORANGE.
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
Activity at the volcano, probably strombolian-type explosions from the summit vent, has increased during the past days. read all
After less than two weeks pause, the volcano started to erupt again - mild strombolian explosions at the summit crater and small ash emissions. read all

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.
