Kizimen volcano (Kamchatka, Russia): partial lava dome collapse produces pyroclastic flows

Multilope pyroclastic flows (block and ash flows) yesterday morning at Kizimen (annotation by Culture Volcan)
Multilope pyroclastic flows (block and ash flows) yesterday morning at Kizimen (annotation by Culture Volcan)
A rock spine that had been growing at the summit of the active lava dome has collapsed, producing pyroclastic flows and an ash plume rising to 20,000 ft (6 km) altitude.
Culture Volcan posted the following time-lapse video from KVERT webcam images:

The collapse of the spine produced an impressive block and ash flow that spit into 3 lobes that traveled down towards the SW, E and NE, reaching a distance of about 2600 m in just 4 minutes, i.e. at a speed of 40 km/h average.

KVERT reports no changes in activity: moderate seismic activity of the volcano suggests that the growth of an extrusion at the volcano summit continues. Incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks, and strong and moderate gas-steam activity accompany this process. (KVERT) [more]
