Volcanos

Roundup of Global Volcanic Activity:

Klyuchevskoy (Kamchatka): Strong explosive and effusive activity continues. KVERT monitors the situation closely and issues alerts every few hours. Last evening, ash emissions again reached almost 30,000 ft (8-9 km) altitude. "The ash plume this morning has decreased in height to 21,300-24,600 ft (6.5-7 km) a.s.l. but by now, an ash plume dangerous for aviation is extending about 736 mi (1188 km) to the south-east and east of the volcano."

Tungurahua (Ecuador): The eruptive phase that had started on 6 Oct, after a quiet interval of 3 months, continues to increase. The volcano observatory reports ash columns rising up to 3 km above the crater and the first occurrence (so far) small pyroclastic flows. In the early days of this phase, seismic activity was characterised by an increase in the number and energy of the events related to the mobilisation of fluids into the volcano such as long-period events, tremor and explosions and emission signals of variable magnitude. Superficially, low intensity strombolian activity and ash emissions could be observed, resulting in ash fall in the areas of El Manzano, Bilbao, Chacauco , Choglontús , Mocha, Pillate and on the upper slopes of the volcano itself.
