Etna (Sicily, Italy): The New SE crater has calmed down. Only very occasionally, a weak glow appeared from the summit vent at night, suggesting deep-seated activity still occurs from time to time.
Small eruption from Fuego yesterday morning
Klyuchevskoy (Kamchatka): Activity has generally decreased over the past days. VAAC Tokyo reported a possible eruption early today, producing a small ash plume rising to 17,000 ft (5.1 km), i.e. a few hundred meters tall. Webcam images at that time are cloudy, but otherwise show the volcano is mostly quiet.
Sakurajima (Kyushu, Japan): Activity seems to increase and decrease in cycles of approximately a week's length. After the series of stronger explosions on 24-25 Nov, the past days have been calmer with fewer and less intense explosions (1-2 per day, ash plumes to 8,000 ft).
Sinabung (Sumatra, Indonesia): Visual activity has decreased. Ash emissions have become less intense and less frequent. However, this could be only a pause, and the risk of larger explosions that can occur unexpectedly remains high.
Dukono (Halmahera): A dense SO2 plume is visible on the latest NOAA satellite data, suggesting that (the ongoing) activity (weak to moderate strombolian explosions) is elevated at the moment.
Kilauea (Hawai'i): Eruptive activity has remained essentially unchanged over the past weeks. The summit lava lake in Halema'uma'u continues to rise and fall with the ongoing cycles of inflation and deflation. No lava flows currently reach the ocean as the Peace Day flow is probably no longer active.
At the middle east rift zone, the Pu`u `O`o vent continued to feed the Kahauale`a 2 lava flow that was active as small scattered breakouts burning forest to the northeast.
Popocatépetl (Central Mexico): CENAPRED reports no changes in activity. The number of explosive emissions of gas/steam and minor amounts of ash is very low (less than 10 per day). Weak glow remains visible at night and SO2 emissions elevated.
A volcano-tectonic quake of magnitude 2.2 was recorded yesterday at 04:33 local time.
Santa María / Santiaguito (Guatemala): Activity has been mainly effusive during the past days; no or few explosions occurred yesterday. The volcano observatory reports abundant avalanches from the active lava flows mainly on the NE side of the Caliente lava dome.
Pacaya (Guatemala): INSIVUMEH reports continuing weak strombolian activity. Small ash plumes at altitudes of 2.5-2.7 km drift up to approx. 10 km mainly to the SE.
Fuego (Guatemala): No significant changes in activity have occurred. The volcano produces small to moderate strombolian-type explosions with ash plumes rising up to about 800 m. The lava flows are no longer active.

Etna (Sicily, Italy): A new paroxysm has started at the New SE crater. Following weak strombolian activity during the past days, this afternoon, started to rise steeply this afternoon. At the time of this update, there are increasingly strong strombolian explosions or pulsating lava fountains at the New SE crater and an ash plume has started to rise. Bad weather inhibits good observations, but occasional views can be obtained especially from the NE side. You can follow the eruption "live" at our interactive webcam viewer. ... [more]

Etna (Sicily, Italy): The New SE crater is restless. Occasional glow from the summit vent suggest that deep-seated strombolian activity continues. At the same time when this activity was visible, a glowing spot at the southern base was present as well. This could be a small effusive vent that is activated briefly during phases the magma column rises high enough inside the conduit. ... [more]
