Etna (Sicily, Italy): Weak explosions continue at the New SE crater, and often produce steam rings. This morning, tremor has started to rise, which could indicate the start of yet another paroxysm.
Ash emission from Copahue yesterday
Klyuchevskoy (Kamchatka): Explosive activity at the summit crater has intensified. The volcano produces a near constant steam and ash plume of fluctuating size. The ash plume reaches about 21,000 ft (6.3 km) altitude drifting east.
Sakurajima (Kyushu, Japan): VAAC Tokyo reports continuous ash emissions and some relatively large explosions with plumes reaching 12,000 ft (3.6 km) altitude last evening.
Bagana (Bougainville Island, Papua New Guinea): An explosion this morning produced an ash plume to 9,000 ft (2.7 km) altitude this morning, VAAC Darwin reported.
Sinabung (Sumatra, Indonesia): Explosions continue to become gradually stronger. Two powerful vulcanian explosions occurred on 14 Nov producing ash plumes rising to about 12,000 ft (3.6 km) and causing small pyroclastic flows. More than 5000 people have been evacuated so far.
Colima (Western Mexico): Activity has increased recently, judging from recent pcitures of the volcano. Abundant rockfalls and lava flows descend the flank of the steep cone. It appears that growth of the lava dome has resumed in speed and overflows the rims of the crater.
Copahue (Chile/Argentina): New ash emissions started yesterday shortly before noon (local time) and have been more or less continuous since then. The low-level ash plume is drifting NW.
SERNAGEOMIN mentions that seismic activity has remained above background, with a total of 18684 recorded earthquakes during October, most of them at depths less than 10 km.

Etna (Sicily, Italy): Activity at the New SE crater has decreased during the night, but probably weak strombolian explosions still occur from time to time. At the moment, weather is very bad and visible observations difficult. The tremor decreased as well, but has gained again and continues to show an overall increasing trend, similar to the days before the 10-11 Nov paroxysm. ... [more]

Etna (Sicily, Italy): The awaited new paroxysm of Etna's NEW SE crater started last night and is still in full progress. Unfortunately, a snow storm above the summit area prevents detailed observations, but judging from the seismic signal, this eruption is unusually long and intense (and still growing at the time of updating). Ash fall has been reported from villages to the E/NE (Zafferana, Milo etc), where the plume is carried to by strong Libeccio winds. ... [more]
