Chile downgrades alert after magnitude 7.4 earthquake spurs tsunami fears

Earthquake off Antarctic coast sparks alarms for coastal areas in southern Chile's Magallanes region due to potential tsunamis. Authorities have downgraded a evacuation alert, advising residents to stay away from shore but evacuating hundreds of people after the quake struck near Antarctica at a depth of just 10 km. The Chilean population there is around 166,000, and local officials are urging calm while SHOA estimates waves could reach extreme southern regions. In Ushuaia, water activities were suspended as authorities prepare for potential impacts.
