Stromboli (Eolian Islands, Italy): Activity has increased: a new lava overflow from the NE rim of the NE crater has started. Tremor and explosion signals are again quite strong, judging from the current seismic signal.
Langila (New Britain, Papua New Guinea): Elevated SO2 emissions are visible on today’s satellite data, indicating ongoing activity. Also Manam volcano remains active and produced an increased SO2 plume.
Nevado del Ruiz (Colombia): A swarm of volcano-tectonic earthquakes occurred late on 7 Feb, suggesting a small magma intrusion, which also resulted in increased SO2 emissions visible on the last NOAA satellite data.
Seismic activity has since decreased again.
A smaller SO2 plume is also visible from Galeras volcano.
