Shiveluch Developments

 The extrusive activity of the volcano has increased.

The local volcanologist Alexey Demyanchuk (volkstat.ru) carried out a field survey in the vicinity of the volcano a few days ago to report that the lava dome is growing again at intense values.

The active lava dome continues to produce frequent incandescent rock falls to the south-southeast, from at least two active areas of the huge dome. From time to time, ash plumes separate from block-and-ash flows (so-called phoenix clouds) as it descends the slope.

Emissions of gas and steam plumes with minor amounts of ash reached heights between 12,000 ft (3,700 m) and 15,000 ft (4,600 m) over the past few days.

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.
