A powerful 7.5-magnitude earthquake struck off the coast of southern Argentina early this morning, prompting tsunami alerts across parts of southern South America and Antarctica. According to the U.S. Geological Survey, the quake’s epicenter was located about 200 kilometers south of Puerto Williams at a depth of 10 kilometers. At least four aftershocks were recorded shortly after the initial tremor.
Officials reported that tsunami waves up to nine feet could impact Chile’s Magallanes Region, while Antarctica may experience waves reaching three feet. Evacuations began along Chile’s southern coastline, with footage showing residents leaving coastal towns such as Punta Arenas. Authorities also reminded families to include pets in their evacuation plans.
Chilean President Gabriel Boric, who was born in the region, urged residents to remain calm and follow official guidance. “All state resources are available,” he said, stressing the importance of prioritizing safety. The Magallanes Region, Chile’s southernmost territory, is sparsely populated but remains highly vulnerable due to its proximity to the earthquake’s epicenter. Emergency teams have been deployed to assess damage and monitor potential risks.
Chile lies along the Pacific “Ring of Fire,” a seismically active zone where tectonic plates frequently collide. The country has a long history of powerful earthquakes, including the 1960 Valdivia quake, the strongest ever recorded. As monitoring continues, regional authorities have urged residents to stay alert for updates and remain cautious near coastal areas
