Volcanos

Roundup of Global Volcanic Activity

Stromboli (Eolian Islands, Italy): The activity of the volcano has been fluctuating between high and medium levels. It is characterized by strombolian explosions from multiple vents in the crater terrace with averages of 22 events per hour during the past day. Tremor and degassing values are at stable, medium levels.  A visitor to the island during the past week and on 26 observed a short-lived small viscous lava flow in the upper Sciara del Fuoco: after a stronger explosion from the western vent, two effusive vents opened in the outer flank of the crater and continuously fed a viscous lava flow, which reached about 50 m length and generated abundant incandescent rockfalls on the steep slope.

Popocatépetl (Central Mexico): (31 Dec) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 24000 ft (7300 m) altitude or flight level 240.

Reventador (Ecuador): (1 Jan) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 27000 ft (8200 m) altitude or flight level 270.

Etna volcano (Italy): Activity at the volcano has increased during the past 24 hours. Mild to moderate strombolian activity resumed at the New SE crater’s summit vent and has been intensifying. The activity at the New SE crater began yesterday at about 16:00 UTC (17:00 local time), ejecting plenty of incandescent lava bombs onto the outer flanks of the cone. At the same time, the mild strombolian activity from vents inside the Bocca Nuova and Voragine summit craters continues at similar intensity as during the previous weeks. An intracrater lava flow produced by this activity was seen active on some photos published on social media. Tremor has increased a bit, but shows no significant variations at the time of this update.

Dukono (Halmahera): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 .
