Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): The New SE crater remains restless. As the following time-lapse video of the past 24 hours shows, there is occasional weak lava extrusion from effusive vents on the upper flanks, and rarely glow from the summit vent suggesting that the magma column is relatively still high inside the vent and sometimes produces deep-seated strombolian explosions.

Ambrym (Vanuatu): NASA astronaut Mike Hopkins captured a great space image of the active Marum and Benbow vents of Ambrym volcano on 2 Dec. Both vents contain active lava lakes.

Santa María / Santiaguito (Guatemala): Explosive and effusive activity have continued with little variation. Explosions sent ash plumes up to 700 m above the crater, and block lava effusion continues mainly at the eastern side of the Caliente dome where weak to moderate constant avalanches occur.

Pacaya (Guatemala): No changes in activity have occurred. Mild strombolian explosions continue from the Mackenney crater. Tremor and explosion signals are visible on the seismic recording.

Fuego (Guatemala): The observatory reports no significant changes. About 30-35 small to moderate explosions occurred during 3-4 Dec, often with strong shock waves that rattled windows and roofs in up to 6 km distance. Ash plumes rose to about 4.2 km altitude (500 m height) and produced light ash falls in W and SW directions (Morelia, Panimache and other villages). At night, incandescent avalanches from the crater are visible.
