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.
Also today, the volcano produces nice steam rings. Tremor is currently low.
Klyuchevskoy (Kamchatka): Activity continues at moderate levels. KVERT reports an explosion this morning and continuous ash emissions reaching 20,000 ft (6 km) altitude and drifting east.
Shiveluch (Kamchatka): Explosive and effusive activity continue. Occasional clear weather webcam images show strong steaming (with some ash?) and warm or hot pyroclastic deposits from recent block avalanches from the growing lava dome. A possible explosion this morning produced an ash plume reported to flight level 170 (17,000 ft / 5 km) altitude and extending SE. (VAAC Tokyo)
Sinabung (Sumatra, Indonesia): More explosions of moderate size have occurred today. The volcano has also been venting ash in a near constant way between single explosions. Ash plumes have reached altitudes of 15-25,000 ft (4.5-7.5 km) and drifted eastwards. The following video shows today's activity:
Llaima (Central Chile and Argentina): VAAC Buenos Aires received a pilot report of a light ash plume between 10,000 and 25,000 ft altitude from the volcano this afternoon. However, this seems to be a false eruption report.
There are no other indications of an eruption and no ash could be seen on webcam and satellite imagery. Local press (who would pick up quickly on activity at one of Chile's most prominent volcanoes) nor SERNAGEOMIN have reported any unusual new activity. It is possible that wind has picked up dust (ash) from the volcano or that a weather cloud was mistaken for an ash plume.
