Bardarbunga (Iceland): The eruption continues at similar intensity as during the past weeks. It also continues to produce spectacular images and videos such as this one from an overflight in late November:

Fogo (Cape Verde): Activity remained similar to the previous days although some sources suggest a decrease in lava effusion, but an increase in explosions at the vents.
Several more houses have been burnt and destroyed by the advancing lava flows in Portela village.

Chirpoi (Kurile Islands, Russia): Thermal hot spots continue to be detected at the summit of Snow volcano. SVERT thinks that a new phase of effusive activity could have been going on since September.
Medvezhia (Kurile Islands, Russia): The Moyorodake-Kudryavy and Chirinkotan volcanoes were placed on yellow alert by SVERT on 27 Nov, as an increase in degassing was observed at both. Recent satellite image shows steam plumes drifting from the volcanoes.
At the moment, 4 of the Kuriles volcanoes are on yellow alert. The other two are Chirpoi since September, Sinarka since 12 Nov.

Raung (East Java): Mild, probably strombolian activity seems to be in progress at the volcano. Since mid November, local observers reported steam plumes and the volcano observatory reported increased seismic activity, typical of mild strombolian activity in the crater.
A hot spot visible on MODIS satellite data fits well into this picture.
Santiaguito (Guatemala): The recently active, viscous lava flow on the southeastern side of the dome might have stopped being alimented, a recent satellite image suggests, showing that the lava flow has not advanced recently, although is still hot. INSIVUMEH no longer reports observed movements at the flow fronts.
Degassing and occasional small explosions continue to occur from the Caliente lava dome.
Nevado del Ruiz (Colombia): According to the latest report of the Manizales observatory, the volcano's activity recently changed and is showing increased signs of unrest, which could announce a new eruption to come.
A recent aerial survey by the Colombian air force revealed a deposit of fresh ash on the southern flank, indicating that at least sporadic explosions or ash emissions - presumably phreatic in nature - do indeed occur.

Fogo (Cape Verde): Although explosive activity has decreased at the vents, it seems that lava effusion picked up. The advance of some of the lava flow fronts in Portela village picked up again this morning, reaching 20 meters per hour. Local sources mention that seismic activity also increased. ... [meer...]

Bardarbunga (Iceland): These two images were posted on the twitter account of the University of Iceland after their recent field expedition. As the lava field continues to expand, new branches of red hot rivers reach its edge and cascade down on the sandy plain below in a spectacular ‘water’fall of glowing lava. Scientists report that by now the Holuhraun lava field covers almost 75 square kilometres which represents an area bigger than the Reykjavik metropolitan area. ... [meer...]
