A new analysis published in Science shows the eruption at Hunga Tonga–Hunga Haʻapai volcano in Tonga on January 15, 2022, created the highest volcanic plume ever recorded. This is the first time a volcanic plume has been seen to penetrate the stratopause.
A powerful eruption started at Sangay volcano, Ecuador at around 11:40 UTC on November 4, 2022.
New activity/unrest was reported for 6 volcanoes from October 26 to November 1, 2022. During the same period, ongoing activity was reported for 16 volcanoes.
Minor eruptive activity is taking place at Cotopaxi — one of the world’s most dangerous volcanoes — since October 21, 2022, prompting IGEPN to raise the Alert Level to Yellow (2 of 4).
New activity/unrest was reported for 9 volcanoes from October 19 to 25, 2022. During the same period, ongoing activity was reported for 15 volcanoes.
Eruptive activity at Anak Krakatau volcano, Indonesia increased again over the past two days, with several low-level eruptions. A total of 7 eruptions were recorded from 10:57 UTC on October 24 to 02:49 UTC today, bringing the total number of eruptions since the start of the year to 78.
An observation flight confirms the active vents at New Zealand’s White Island volcano are continuing to emit a moderate steam and gas plume, with rare periods of ash emission. The Volcanic Alert Level remains at 2.
An intense thermal anomaly was detected over Alaid volcano, Atlasov Island, Russia at 00:39 UTC on September 15, 2022, signaling the beginning of a new Strombolian explosive eruption after several years of quiescence.
Researchers reporting in AGU’s Geophysical Research Letters show that the seismic swarm detected near Mt. Edgecumbe volcano in Southeast Alaska, U.S. in April 2022 was caused by magmatic activity taking place under this transform fault volcano previously considered dormant.
A strong explosive eruption took place at Bezymianny volcano, Russia on October 23, 2022, ejecting ash up to 10 km (32 800 feet) above sea level. The Aviation Color Code was raised to Red at 12:20 UTC and lowered back to Orange at 22:05.
