Roundup of Global Volcanic Activity

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. 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 after 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. 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.

Sinabung (Sumatra, Indonesia): Activity continues at the lava dome feeding a viscous flow on the upper southern slope. A moderately large pyroclastic flow occurred this morning.

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.
