A 7.5-magnitude earthquake struck off southern Argentina early this morning, with its epicenter about 200 kilometers south of Puerto Williams at a depth of 10 kilometers, according to the U.S. Geological Survey. At least four aftershocks followed.
Tsunami warnings were issued across southern South America and Antarctica. Officials warned waves could reach “up to nine feet” in Chile’s Magallanes Region and about “three feet” in Antarctica. Evacuations began along Chile’s southern coast, with footage showing residents leaving Punta Arenas and nearby towns. Authorities urged families to take pets with them.
Chilean President Gabriel Boric, a native of the region, told residents, “All state resources are available,” stressing calm and strict adherence to safety instructions. Emergency crews have been deployed to assess damage and risks.
The Magallanes Region is sparsely populated but highly exposed due to its closeness to the epicenter. Its communities face particular vulnerability in such events.
Chile sits on the Pacific “Ring of Fire,” where earthquakes are common. The country has experienced some of the strongest quakes in history, including the 1960 Valdivia quake. Authorities continue to monitor the situation and urge residents to stay alert near coastal areas.
