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.
Southern and Central Provinces of Zambia are grappling with a “catastrophic situation” after prolonged rainfall caused widespread flooding. The floods caused damage to homes and farmlands as well as disrupted access to healthcare and education in communities in Bwengwa, Namwala, Monze in Southern Province, and Mumbwa district in Central Province since mid-January 2023.

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.
