Piton de la Fournaise volcano on La Réunion entered a new eruptive phase at 19:42 LT (16:42 UTC) on January 18, 2026, after a strong seismic crisis and rapid ground deformation. The eruption is effusive, producing lava flows from fissures on the northern flank inside the Enclos Fouqué caldera. This is the first eruption at Piton de la Fournaise since August 2023.
A notable increase in seismic activity was detected at Pavlof volcano on the Alaska Peninsula on January 14, 2026, prompting the Alaska Volcano Observatory (AVO) to raise the alert level to Advisory and the Aviation Color Code to Yellow. No surface activity or eruptive changes were observed, and seismicity has since declined to background levels.
New activity/unrest was reported for 5 volcanoes from January 8 to 14, 2026. During the same period, ongoing activity was reported for 22 volcanoes.
New activity/unrest was reported for 9 volcanoes from January 1 to 7, 2026. During the same period, ongoing activity was reported for 15 volcanoes.
Nearly 3 000 residents have been evacuated from communities around Mayon volcano in Albay Province, Philippines, after the Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert status to Level 3 on January 6, 2026. The evacuation follows intensified dome collapse events, pyroclastic density currents, and ongoing effusive lava extrusion at the summit.
PHIVOLCS raised Mayon Volcano’s alert status to Level 3 on January 6, 2026, following intensified dome collapse events and effusive lava extrusion at the summit crater. The next day, Tokyo VAAC reported a brief ash emission to 2 700 m (9 000 feet), consistent with ongoing shallow magmatic activity.
Etna’s eruptive activity intensified rapidly between December 24 and 27, 2025, culminating in short-lived lava fountains about 200 m (650 feet) high and a new lava flow from the upper Voragine crater toward the Valle del Bove. INGV Etna Observatory (OE) raised the Aviation Color Code to Red on December 27 as tremor and infrasound amplitudes reached very high levels.
Kīlauea entered eruptive episode 39 at 20:10 HST on December 23, 2025 (06:10 UTC on December 24) as lava fountains rose from twin vents on the floor of Halemaʻumaʻu crater. Within about 95 minutes, fountain heights increased from 10 m (30 feet) to more than 420 m (1 400 feet), with lava flows covering 10–20% of the crater floor by 21:14 HST and a plume reaching 6 000 m (20 000 feet).
A large lahar triggered by heavy rains on Mount Semeru trapped a man in the Regoyo River in East Java, on Sunday, December 21, 2025.
A powerful lava fountain from Kīlauea’s Halemaʻumaʻu crater, Hawaiʻi, destroyed the USGS Hawaiian Volcano Observatory’s V3 streaming camera at around 10:00 HST (20:00 UTC) on December 6, 2025. The camera was recording live when an inclined fountain from the south vent buried it in hot pumice and tephra during Episode 38 of the ongoing summit eruption.
