A strong earthquake struck off the coast of southern Chile on Friday morning, prompting an evacuation alert for several regions along the country’s southern edge. According to the US Geological Survey, a magnitude-7.4 tremor occurred about 135 miles south of Ushuaia, Argentina. The National Weather Service’s Pacific Tsunami Warning Center initially reported tsunami waves of 3 to 10 feet possible by 11:22 a.m. local time, but later canceled the alert.
However, the center did confirm that a small 0.4-foot tsunami wave was observed at Vernadsky Research Base in Antarctica. The evacuation alert for coastal areas along Chile’s Strait of Magellan and beach areas in the Magallanes region were issued as a precautionary measure. Fortunately, no injuries or damage have been reported, with local authorities advising residents to remain calm during such events.
