Active vents of Nakadake crater, Aso volcano (Japan)
Aso (Kyushu): The volcano is active from 2 vents in the Nakadake crater. During the night, sometime strong incandescence, suggesting possible weak (strombolian-type) ejections of lava, steaming and minor ash venting are visible.
The probably largest-so-far pyroclastic flow at Sinabung this morning
Sinabung (Sumatra, Indonesia): After a few days of deceiving calm, the eruption of the volcano intensified again today and produced the so-far largest pyroclastic flows, reaching probably more than 5-6 km in length, and associated ash plumes that rose to approx. 25,000 ft (8 km) altitude:

Dukono (Halmahera): More explosions occurred today at the volcano. Ash plumes were reported at 10,000 ft (3 km) altitude extending up to 60 nautical miles to the NE.
Pacaya (Guatemala): The volcano continues to effuse a weakly alimented lava flow from the southern fissure and has mild strombolian activity at the summit crater, with explosions occurring about every 2 minutes and ejections reaching 25-70 m above the crater.
Fuego (Guatemala): Activity continues at moderate levels as during the past days. INSIVUMEH counted 13 moderate explosions with shock waves and ash plumes rising 300-800 m. The lava flow on the upper southern slope towards the Trinidad drainage was 300 m long this morning.

Etna (Sicily, Italy): The activity of the volcano has remained similar to the previous days: so far, relatively weak but more or less steady ash emissions are occurring at the North-East crater, and tremor continues its slow rise. Whether this is a precursor to more vigorous activity (from the New SE crater?) remains to be seen probably in the coming days. ... [mehr]
