Klyuchevskoy volcano (Kamchatka): second lava flow

Klyuchevskoy volcano with the new lava flow last evening (KVERT webcam)
Lava effusion continues. Since the night 10-11 Sep, the lava has changed path and now feeds a second lava flow a bit to the north from the previous one, making it better visible from the KVERT webcam located north of the volcano.

Small steam plume from active Klyuchevskoy volcano this morning
The effusion of a lava flow on the SW flank and strombolian activity at the summit vent continue. Avalanches are being formed from detaching lava blocks from the flow on the steep flow. KVERT reports moderate seismic activity with strong tremor, that obscure the signal from nearby Bezymianny volcano. A large thermal anomaly can be seen on satellite data. read all

Klyu seen from the KVERT observatory this morning; the lava flow is indicated by the white plume rising on the right side of the upper flank
A small lava flow has started to descend on the upper northern flank of the volcano. Sometimes intense strombolian continues at the summit vent. Glowing blocks from the lava flow often detach from the front and roll down the steep slope of the volcano. No significant ash emissions have occurred so far. ... read all

Relatively intense strombolian activity continues at the summit. Bright glow can be seen at night. Both webcam images and MODIS hot spot data indicate the occurrence of hot avalanches on the slopes of the volcano as well. read all

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.
