A new degassing pit crater was identified at 3.1 km (10 170 feet) a.s.l. on the southern flank of Etna’s Bocca Nuova Crater on February 28, 2025. A modest lava overflow was also observed from the Southeast Crater at 07:00 LT (06:00 UTC), producing a lava flow on the upper southern flank of the crater.
New activity/unrest was reported for 8 volcanoes from February 19 to 25, 2025. During the same period, ongoing activity was reported for 20 volcanoes.
The Frans Xavier Seda Airport was temporarily shut down on Wednesday, February 26, 2025, after an eruption at Lewotobi Laki-Laki.
Nearly a month after satellites detected massive methane plumes spewing from Ethiopia’s Mount Fentale on January 31, 2025, new data shows emissions have declined since February 9—yet ongoing seismic unrest, including a magnitude 6.0 earthquake on February 14, keeps scientists and locals on high alert.
Over 600 earthquakes were recorded at Campi Flegrei, Italy, between February 17 and 23, 2025, with the largest measuring M3.2. Around 1 cm (0.4 inches) of ground uplift was observed in the area of maximum deformation, coinciding with the onset of an earthquake swarm on February 15.
A drone video captured on February 24, 2025, shows the evolving lava field from an ephemeral vent at 3.05 km (10 006 feet) a.s.l. on the southwestern slope of Mount Etna, Italy.
Small ash emissions along with large white steam plumes have been observed over the past week at White Island volcano in New Zealand, according to a bulletin released by the GNS at 14:30 LT (01:30 UTC) on Monday, February 24, 2025. The Alert Level remains at 2 while the Aviation Color Code has been raised to Orange.
Magma accumulation beneath Svartsengi has reached a critical volume, matching the levels observed during the last eruption on November 20, 2024. A volcanic eruption could occur at very short notice, potentially within days or weeks, according to the IMO. The IMO has revised its hazard assessment which remains in effect until February 25.
A small explosive event was recorded at the Atka volcanic complex in the Aleutian Islands, U.S., at 19:26 LT on February 20, 2025 (04:26 UTC on February 21). The Aviation Color Code has been raised to Orange and Alert Level to Watch.
Magma accumulation beneath Svartsengi is nearing the critical threshold, with over 90% of the volume recorded before the last eruption on November 20, 2024, increasing the likelihood of a dike intrusion and possible eruption. Seismic activity remains steady, and land uplift continues.
