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 followed soon after, shaking nearby regions and heightening fears of potential damage.
Officials warned that tsunami waves up to nine feet could impact Chile’s Magallanes Region, while parts of Antarctica might see waves reaching three feet. Emergency sirens echoed through coastal towns as evacuations began in Punta Arenas and surrounding communities. Videos circulating on social media showed residents fleeing to higher ground, carrying essentials, pets, and livestock as authorities urged preparedness and calm.
Chilean President Gabriel Boric, who hails from the affected region, addressed the nation urging unity and caution. “All state resources are available,” he said, reaffirming that protecting lives remains the government’s top priority. Temporary shelters were quickly set up, power outages reported, and teams dispatched to assess structural damage across the Magallanes Region, one of Chile’s most remote yet vulnerable areas.
Experts reminded the public that Chile sits on the Pacific Ring of Fire, one of the planet’s most seismically active zones, where tectonic shifts frequently trigger major quakes. The 1960 Valdivia earthquake, the strongest ever recorded globally at 9.5 magnitude, still serves as a stark reminder of the region’s volatility. Authorities continue to urge residents to stay away from coastlines, follow official updates, and remain on alert until tsunami warnings are officially lifted.
