Worldwide Volcano News and Updates

IG reported that, during the last week of October and the first days of November, moderate activity continued at Tungurahua; there were ~10 explosive emissions recorded. Plumes reached 800-2,000 m above the crater and drifted E and SE; ashfall was not reported from nearby communities. Seismicity included explosions, long-period earthquakes, volcano-tectonic earthquakes, and tremor (often associated with emissions). Read all

An eruption began at 0126 on 3 November that generated ash plumes up to 7 km a.s.l. (~23,000 ft) and triggered evacuations from communities within 3 km of the volcano (approximately 1,681 residents); the ash plume drifted W. Rumbling sounds that lasted up to 10 minutes long were noted by staff at the Sinabung Observation Post (~8.5 km from the volcano). Read all

KVERT reported that the current eruption continued through the week and included several strong ash eruptions that sent plumes to altitudes of 7-10 km (~22,000-33,000 ft) and drifted more than 200 km to the NE. Visual and satellite observations determined that lava extrusion continued on the NE and N flanks of the lava dome. This viscous block lava generated moderate ash explosions; fumarolic activity, hot avalanches, and incandescence at the summit also continued. Read all

INGV reported on 5 November that, after 10 days of relative quiescence, the New Southeast Crater (NSEC) showed signs of activity. A brief glow seen on surveillance cameras was followed by ash emissions. The event was accompanied by a strong seismic signal detected by summit seismic stations. Read all

Etna (Sicily, Italy): The New SE crater has remained quiet since yesterday, although seismic activity remains above background. Strong degassing is visible from Bocca Nuova. Read allThe volcano had at least 6 vulcanian explosions yesterday. The largest (at 08:09 local time this morning) sent an ash plume to 15,000 ft (4.5 km) altitude. Read all

Etna (Sicily, Italy): Tremor has remained elevated and the New SE crater continued to produce weak strombolian activity and aliment the lava flow during much of the night. At the moment (Sunday morning), it is not clear if this activity is continuing. Read allA new explosion occurred yesterday evening (17:40 local time), producing an ash plume rising 2-3 km above the crater and causing ash fall in nearby villages.
