Block-and-ash flows, caused by gravitational collapse of the new dome part of the existing lava dome, started to descend at about 00:53 local time today that traveled over Vostochnaya and Yuzhnaya gullies.
Ash plumes, separated from pyroclastic density currents (so-called phoenix clouds), reached 38,000 ft (11,600 m) altitude and drifted to the N-NE of the volcano. A huge and dense ash cloud with dimensions up to about 160x320 km has been carried about 620 km away from the volcano.
Continuing rise of viscous fresh magma into the extruded lava dome has been accumulating and turn develop into dangerous pyroclastic flows.
The local volcano observatory reported that the intense activity of the volcano ended and only continues with moderate gas and steam emissions for now.
