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.
A large fissure opened up last week in the southern part of Grímsfjall, near Grímsvötn subglacial volcano in Iceland. Pictures show that there’s a lot of hydrothermal activity in this fissure, but there is no eruption at this moment.
New activity/unrest was reported for 8 volcanoes from October 12 to 18, 2022. During the same period, ongoing activity was reported for 16 volcanoes.
Two earthquakes with magnitudes above M3 were detected in Mýrdalsjökull glacier on October 16, sparking discussions about a possible eruption of Katla volcano.
An explosive eruption began at Chikurachki volcano at around 15:10 UTC on October 15, 2022, producing an eruptive column up to 4.5 km (14 700 feet) above sea level.
Heightened unrest continues under Mauna Loa, with two moderately strong earthquakes within 24 seconds on October 14, 2022, and a string of aftershocks that are still taking place. The unrest is likely caused by renewed input of magma into Mauna Loa’s summit reservoir system. The Alert Level remains at Advisory and the Aviation Color Code at Yellow.
Increased activity under Bulusan volcano, Philippines prompted PHIVOLCS to raise the Alert Level for the volcano from 0 to 1 on October 13, 2022.
A red glow appeared at the top of Nyiragongo volcano in the Democratic Republic of Congo on October 11, 2022, after a rapid magmatic supply to its crater. The Alert Level remains at Yellow.
