Effusive lava activity has been observed with lava overflowing from the northern summit area at Stromboli volcano, Italy since 07:08 LT (06:08 UTC) on February 6, 2025. The Aviation Color Code remains at Orange.
An earthquake swarm began in the Campi Flegrei area of southern Italy at 08:03 LT (07:03 UTC) on February 5, 2025.
An eruption at Bezymianny volcano in Kamchatka, Russia, sent ash up to 4 km (13 123 feet) a.s.l. and triggered seismic activity at 10:20 LT (00:20 UTC) on February 1, 2025. KVERT raised the Aviation Color Code to Orange on January 31, marking the first upgrade in three months since October 4, 2024.
During a nighttime eruption on Thursday, January 30, 2025, the Sakurajima volcano produced an impressive volcanic lightning show, a rare but well-documented phenomenon associated with explosive eruptions.
New activity/unrest was reported for 5 volcanoes from January 22 – 28, 2025. During the same period, ongoing activity was reported for 19 volcanoes.
A series of more than 130 earthquakes, reaching up to M3.0, has been detected near the Santorini summit since January 28, 2025, prompting an emergency government meeting by the Permanent Scientific Monitoring Committee to assess potential volcanic risks.
Magma continues accumulating beneath Svartsengi at a rate nearing the levels observed before the previous eruption. Deformation measurements confirm ongoing ground uplift, with geophysical models estimating that the subsurface magma volume is approaching the threshold associated with past magma intrusions.
The Scientific Committee for the Evaluation and Monitoring of Volcanic Phenomena (CCES) has confirmed that the Teide volcano in Tenerife, Spain is exhibiting anomalous geophysical activity, characterized by increased seismicity, geodetic deformation, and gas emissions. While there are no indications of an imminent eruption, experts acknowledge an elevated likelihood of volcanic activity in the medium to long term.
New activity/unrest was reported for 9 volcanoes from January 15 – 21, 2025. During the same period, ongoing activity was reported for 13 volcanoes.
A period of increased seismic activity was detected at the Kama’ehuakanaloa Seamount on January 21, 2025. While the exact cause remains undetermined, the seismic activity may be linked to magma movement beneath the volcano.
