Stronger explosions can occur any time.
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 characterized by an increase in the number and energy of the events related to the mobilization 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.

Klyuchevskoy (Kamchatka): VAAC Anchorage sent out a message shortly before midnight (UTC) that the "eruption has ended" based on the absence of ash emissions from satellite imagery and pilot observations. This followed a particularly strong explosive phase that apparently occurred last night, when seismic data suggested strong emissions and an ash plume rose to possibly 33,000 ft (10 km) altitude. Webcam images from last night showed strong glow from lava flows and summit activity, but today the volcano has been hidden in clouds and no direct views have been possible so far. ... Read all
