  • Strong and shallow M6.0 earthquake hits Mindanao, Philippines

    A strong and shallow earthquake registered by the USGS as M6.0 hit Mindanao, Philippines at 10:44 UTC on February 1, 2023. The agency is reporting a depth of 13.5 km (8.3 miles). EMSC is reporting M6.0 at a depth of 10 km (6.2 miles); PHIVOLCS M6.0 at a depth of 27 km (16.8 miles).

  • Extensive and very dangerous ice storm hits U.S.

    A glancing blow of Arctic air mixed with a surge in moisture set the stage for an extensive and very dangerous ice event in parts of the United States. The most likely corridor of icing with a mixture of sleet will occur from west-central Texas to the Tennessee and Lower Ohio Valleys. The ice accretion from Texas into Mid-South may approach 13 mm (0.5 inches) or more through Wednesday, February 1, 2023, and cause power outages and travel issues.

  • Catastrophic flooding devastates Zambia, displaces thousands

    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. The government has assured a multi-sectorial response to ensure recovery and rehabilitation.

  • 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.
