The intense activity of the volcano persists.
Dense grey abundant ash emissions have been bursting from the actively growing lava dome today. This might be caused by either a continuous eruption or ash plumes (so-called phoenix clouds) separating from pyroclastic density currents (block-and-ash flows) as they descended the slope or both phenomena. The Volcanic Ash Advisory Center (VAAC) Tokyo reported at about 18:00 local time the ash plume which reached to 17,000 ft (5,200 m) elevation and dissipated about 10 km to the east of the volcano.
The active lava dome continues to grow and produce frequent incandescent rock falls to the south-southeast.
As time passes and the dome continues to grow larger and larger, the risk of a sudden, potentially very large collapse event resulting in massive pyroclastic flows and explosions increases. Pyroclastic flows are deadly, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes.
OMG I can’t tell you how many hours I’ve spent waiting to capture this. It still isn’t the I’m waiting for but it’ll do for now This was an hour ago….#Shiveluch #Volcano #Kamchatka #Russia #Eruption pic.twitter.com/loydGUh9VS
