7.5-Magnitude Earthquake Triggers Tsunami Alerts in Chile and Antarctica
A 7.5-magnitude earthquake struck off southern Argentina early today, prompting tsunami warnings in southern Chile and Antarctica. The quake, centered 200 km south of Puerto Williams at a depth of 10 km, triggered at least four aftershocks. Chile’s Magallanes Region could see waves up to 9 feet, while Antarctica may face waves up to 3 feet. Evacuations are underway, with residents fleeing coastal towns like Punta Arenas. Chilean President Gabriel Boric urged compliance with safety measures. Though sparsely populated, the region is at high seismic risk. Chile remains vulnerable due to its location on a major tectonic boundary.
