On February 22, 2023, the Alaska Volcano Observatory (AVO) raised the alert level of Trident Volcano to ADVISORY and the Aviation Color Code to YELLOW due to an increase in seismic activity beneath the volcano. The last eruption at this volcano was in 1974 (VEI 3).
The Alaska Volcano Observatory (AVO) has raised the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY for Aniakchak volcano on February 23, 2023, following an increase in seismic activity. The last eruption at this volcano took place in 1931 (VEI 4).
New activity/unrest was reported for 5 volcanoes from February 15 to 21, 2023. During the same period, ongoing activity was reported for 17 volcanoes.
New activity/unrest was reported for 5 volcanoes from February 8 to 14, 2023. During the same period, ongoing activity was reported for 18 volcanoes.
New activity/unrest was reported for 5 volcanoes from February 1 to 7, 2023. During the same period, ongoing activity was reported for 17 volcanoes.
New activity/unrest was reported for 7 volcanoes from January 25 – 31, 2023. During the same period, ongoing activity was reported for 18 volcanoes.
A submarine volcano located near the island of Epi in Vanuatu started erupting at 18:30 UTC on January 31, 2023, prompting authorities to raise the Volcano Alert Level to 1 and establish a 10 km (6.2 miles) danger zone. This marks the first eruption of the volcano since 2004 (VEI 2).
A seismic swarm started under the Asosan volcano in Japan on January 30, 2023, prompting the Japan Meteorological Agency (JMA) to raise the Volcanic Alert Level from 1 to 2.
An explosive sequence at the Stromboli volcano in Italy on January 30, 2023, caused the launch of coarse pyroclastic material at several hundred meters in height and produced an ash cloud that quickly dispersed southward.
Seismic activity around Chile’s Lascar volcano has increased over the past 2 days, causing Sernageomin to raise its Alert Level to Orange. The security perimeter around the crater was expanded to 10 km (6.2 miles), with the community urged to avoid unnecessary exposure to potential dangers. The seismicity is primarily linked to fluid dynamics within the volcanic system, which could be a result of the destabilization of a remnant magmatic body. This activity could lead to explosive events, potentially causing ashfall in the area.
