East Epi submarine volcano erupts for the first time since 2004, 10 km danger zone established, Vanuatu
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).
Earthquake swarm under Asosan volcano, Alert Level raised, Japan

Sequence of strong explosions at Stromboli volcano, Italy
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.
Increased seismicity at Lascar volcano, Alert Level raised to Orange, Chile
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.
The Weekly Volcano Activity Report: January 18 – 24, 2023
New activity/unrest was reported for 4 volcanoes from January 18 to 24, 2023. During the same period, ongoing activity was reported for 21 volcanoes.
