Bardarbunga (Central Iceland): The eruption at the Holuhraun fissure goes strong into the new year and might continue for a while. No significant changes have occurred recently.
The lava field is now well over 82 square km large, a mapping from 29 Dec. shows.
Seismic activity remains concentrated around the summit caldera of Bardarbunga central volcano, while it is very low beneath the erupting dyke – magma has an open conduit towards the surface.
Fogo (Cape Verde): The eruption continues at reduced pace. After slowing down, lava effusion and small explosive activity at the vents appear to have increased again on 31 Dec. The western lava flow remains active with its northern front advancing through farmland in the Cha caldera.
Kliuchevskoi (Kamchatka): The volcano entered a new phase of activity which is taking place in the summit crater.
On 29 December, Tokyo VAAC reported that fresh ashes were observed on the slopes of Klyuchevskoy. KVERT now changed the status level from green to yellow, as additional signs of volcanic activity have been gathered recently:
Increased seismic activity has been noted since 19 Dec. A small plume could be detected from Klyuchevskoy volcano on satellite imagery from 2 January. A thermal anomaly is visible o satellite data as well, and last, but not least, during clear weather, glow can be seen from the summit at night.
Colima (Western Mexico): Activity of the volcano remains stable at low to moderate levels. Viscous lava is being extruded at the summit crater, forming a flat lava dome that is overspilling in several places, producing a short lava flow and incandescent rockfalls.
Intermittent small explosions occur as well, producing occasional ash plumes.
Popocatépetl (Central Mexico): Activity continues essentially unchanged. A small lava dome continues to grow inside the inner summit crater, with glow visible at night.
Frequent steam emissions and occasional small explosions (1 or 2 per day) produce steam and sometimes ash plumes.
