• Increased seismicity at Lascar volcano, Alert Level raised to Orange, Chile

    ByTeo Blašković

    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.

  • Decades-long growing rift in Brunt Ice Shelf finally breaks, creating new iceberg, Antarctica

    ByTeo Blašković

    On January 22, 2023, a massive rift on the Brunt Ice Shelf in Antarctica finally gave way, resulting in the formation of a new iceberg measuring 1 550 km2 (~600 mi2). The U.S. National Ice Center has named it Iceberg A-81. The rift, spanning most of the Brunt Ice Shelf in Antarctica, appeared ready to spawn an iceberg in 2019, posing an uncertain future for scientific infrastructure and a human presence on the shelf that was first established in 1955 by the British Antarctic Survey (BAS).
