Map of today’s active volcanoes

Stromboli (Eolian Islands, Italy): (29 Dec) The effusive-explosive eruption at the volcano continues.
The lava continues to supply the flow on the Sciara del Fuoco at a decreased rate, even though it seems to advance slowly towards the sea visible from the latest Sentinel-2 satellite cloud-free image.

The typical spattering activity in combination with strombolian-type explosions continue to take place from the North and Central-South crater area.
The volcanic tremor didn’t show significant variations.

A satellite image from mid-December shows a visible glowing inner summit area and gas emissions suggesting rise of fresh juvenile magma in the conduit.
The Volcanic Alert Level remains at Level 2. The public was reminded not to enter the restricted area within 600 m around the cone, defined by Danger Zone A on the hazard map.

Semisopochnoi (United States, Aleutian Islands): (29 Dec) The Alaska Volcano Observatory raised the alert level to „Orange“, as the eruptive activity renewed over the past 24 hours.
Minor ash deposits have been registered on the snow-covered flanks of the north crater of Mount Cerberus, at about 1 km distance from the vent.

No ash plumes have been observed in the web camera or satellite imagery, but sustained ash plumes have continued to rise up to 5,000 ft altitude carrying volcanic ash within it.
The AVO continues: „Small eruptions producing minor ash deposits within the vicinity of the active north crater of Mount Cerberus and ash clouds usually under 10,000 ft (3 km) above sea level have characterized the recent activity and more ash-producing events could occur again with little warning. Semisopochnoi volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.“
