A phreatic eruption occurred at the Mayon volcano summit on Sunday, February 4, 2024, at 08:37 UTC, lasting 169 seconds. The event generated a 1 200 m (4 000 feet) tall ash plume , rockfalls and pyroclastic flows. The volcano’s Alert Level remains at 2 and authorities are reminding the public to avoid the Permanent Danger Zone.
Updated findings as of February 1, 2024, show a heightened eruption risk near Grindavík, with about 6.5 million cubic meters (229 million cubic feet) of magma flowing into the Svartsengi chamber.
New activity/unrest was reported for 3 volcanoes from January 24 to 30, 2024. During the same period, ongoing activity was reported for 17 volcanoes
Icelanders build massive dykes to protect against lava flows from reactivated volcanoes near Reykjavik. The six volcanic systems, active for the first time in nearly 800 years, pose a significant threat to the Reykjanes peninsula, prompting around-the-clock construction efforts to safeguard homes and a crucial power plant.
Eruptive activity at Indonesia’s Ibu volcano continues with strong explosions from the cinder cone within the summit caldera.
Increased earthquake activity and signs of magma movement beneath Kīlauea’s summit, detected on January 31, 2024, have prompted the USGS Hawaiian Volcano Observatory to elevate the volcano’s alert level from ADVISORY/YELLOW to WATCH/ORANGE. With over 500 earthquakes recorded since midnight and ground deformation indicating pressurized magma chambers, the risk of an eruption remains high.
Þorvaldur Þórðarson, a volcanology professor at the University of Iceland, suggests that recent earthquakes in the Reykjanes Peninsula could indicate magma accumulation under Húsfellsbruna, raising concerns about potential lava flows near Reykjavík.
The Alaska Volcano Observatory reported a continuous slow eruption of lava in the summit crater of Great Sitkin Volcano as of 19:30 UTC on January 30, 2024. The Aviation Color Code remains at Orange and Alert Level at Watch.
In recent days, Svartsengi, Iceland, has experienced accelerated land rise, reaching up to 8 mm (0.3 inches) daily, attributed to magma accumulation under the area. While seismic activity remains mild, the risk assessment for Grindavík has been downgraded to orange, with a continued high risk for crack collapse.
New activity/unrest was reported for 4 volcanoes from January 17 to 23, 2024. During the same period, ongoing activity was reported for 12 volcanoes.
