Based on a pilot report, the Washington VAAC reported that an ash plume from Sangay rose to an altitude of 7.6 km (25,000 ft) a.s.l. on 23 December....mehr
An eruption plume from Popocatépetl rose to an altitude of 7.9 km (26,000 ft) a.s.l. and drifted E on 20 December, 2006....mehr
Karymski volcano continues to have powerful strombolian to vulcanian type eruptions, producing ash plumes to 7 km (23,000 ft) a.s.l.
After a week of intense vulcanian activity, Shiveluch's activity has decreased again on 28 December 2006, but new explosions can be expected any time.

Over the past weeks, the lava dome continued to grow at Soufrière Hills, mainly on the SW part of the dome. Rockfalls and pyroclastic flows occurred on the S side of the dome and in the upper parts of both White's and Tuitt's Ghauts. On 23 and 24 December, ash plumes rising to 3 km were observed and MVO reported that the emissions originated from a vent on the W side of the dome. A small pyroclastic flow was visible NW in the upper reaches of Tyre's Ghaut and venting became more energetic. The alert level was raised to 4 (on a scale of 0-5). At night, incandescent rockfalls were visible from the NW and W....mehr

A paroxysmal (sub-Plinian) explosive eruption at Bezymianny began at 09:17 UTC on December 24 and ended in the afternoon the same day. A large eruption column rose up to ~ 10.0 km (32,800 ft) ASL and assumed the typical umbrella shape. An ash plume extended to the north-east from the volcano.
KVERT reports increased seismic activity at Sheveluch volcano, warning that ash explosions up to 10 km (32,800 ft.) ASL could occur at any time. Sheveluch's lava dome continues to grow.

KVERT reports significantly increased seismic activity ata Bezymianny volcano. A series of ash explosions and pyroclastic flows were recorder starting from 23:52 UTC on December 23. Ash plumes rose up to 6.0 km (19,700 ft) ASL and extended to the north-east from the volcano.
As the Goma Volcano Observatory reports, the eruption at Nyiamuragira that had started on 27 November is probably close to its end. Lava emission from the eruptive fissure has been decreasing to a very low level. Due to the difficulty to access the eruption site because of hostile militant groups in the area, exact observations other than by overflights are near impossible.

According to the Volcanological Survey of Indonesia, seismic signals from rockfalls increased at Soputan during 11-13 December. On 14 December, ash clouds rose to an altitude of 2 km (6,600 ft) a.s.l. and ash fell within a 15 km radius of the peak. The emissions were accompanied by thunderous noises that were heard 8 km from the peak. On 15 December the Alert Level was raised from 2 to 3 (on a scale of 1-4) due to this increase in activity.

The eruption at Piton de la Fournaise continues unabated. Lava continues to flow from the vents inside Dolomieu crater and since 3 weeks, it has been overflowing Dolomieu crater's rim and the flow fronts are advancing slowly but surely towards the coast. As of 19 December, the most advanced fronts of the lava are now well on the vegetated Grand Brûlé slope at about 800 m elevation, ca 3 km away from the National Road....mehr [alles lesen]

As INGV reports, an unusually strong eruption occurred at Stromboli on 15 December 2006. Bombs landed on both Pizzo and the Sciara del Fuoco, reminding that it is not completely safe to stay on Pizzo.

Explosive eruption continues at Karymski volcano. According to KVERT, on December 17, 2006, an ash plume rising up to 7.0 km (23,000 ft.) ASL and extending to the east from the volcano was observed by pilots.
Strong explosive activity at Sheveluch continues. KVERT reported that on December 17, 2006, an ash plume rose up to 8.0 km ASL and extended to the east from the volcano.

Over the past night, a new effusive vent opened and started to erupt a new, well-alimentated lava flow. This comes after a pause in eruptive activity over the past daysw. The new vent is located in the Valle del Bove headwall, at ca. 2800 m east of SE crater and near the location of the vent that had been activive during the past two months. The onset of activity was accompanied by an augmentation of tremor level as well weak ash emissions from the SE crater itself.

Piton de la Fournaise volcano (La Réunion), activity update: lava lakes, flows overflowing Dolomieu crater
Piton de la Fournaise's eruption is well into its third month of activity. A small lava lake is present inside the younger of the two new cones, baptised Piton Moinama and its precessor Piton Wouandzani, both built up during the current eruption inside Dolomieu crater.

Based on pilot reports and satellite imagery, the Washington VAAC reported that an eruption from Sangay on 2 December produced an ash plume that rose to an altitude of 8.5 km (28,000 ft) a.s.l. and drifted SW.
Discrete small to moderately sized ash eruptions continue to occur typically every few hours at Colima volcano. Ash plumes reach altitudes of up to 5-7 km.

Preceded by half an hour of strong tremor, Sheveluch volcano erupted with a violent explosion that produced an ash plume rising to about 6 km that drifted north and has already reached more than 100 km distance. Pyroclastic flows descended on the slope along the Baidarnaya River....mehr

Etna volcano (Italy), activity update: continuing weak strombolian activity at SE crater and lava emission from subterminal fissure vents
The pit crater on the upper eastern flank of the SE crater continues to produce relatively mild strombolian activity originating from two vents.

Etna volcano (Italy), activity update: new weak eruptive episode, new effusive fissure at base east of cone
A new eruptive episode of Etna's SE crater occurred on 1 December, characterized by weak strombolian activity and ash production from a vent near the summit of SE crater and a new effusive fissure vent at its base:
We regret to post a very sad volcano-related news entry. Heavy rainfall from the exceptionally strong typhoon Durian that hit the Philippines a few days ago triggered a series of huge mud flows and landslides on the slopes of Mayon volcano (which itself has been quiet for over a month now, but accumulated lots of fresh deposits in its last eruptive phase in the summer 2006).
