7.5-Magnitude Earthquake Sparks Tsunami Fears in Chile and Antarctica

A powerful 7.5-magnitude earthquake struck off the coast of southern Argentina early this morning, triggering tsunami warnings across southern Chile and parts of Antarctica.

The quake occurred about 200 km south of Puerto Williams at a depth of 10 km, according to the U.S. Geological Survey. At least four aftershocks followed.

Tsunami waves up to 9 feet could strike Chile’s Magallanes Region, with Antarctica expecting waves up to 3 feet, officials warned.

Evacuations began along Chile’s southern coastline, with footage showing residents and cars fleeing towns like Punta Arenas. Authorities emphasized the importance of including pets in evacuation plans.

Chilean President Gabriel Boric, a native of the region, urged people to follow official instructions, stating: “All state resources are available.”

The Magallanes Region, Chile’s southernmost area, is sparsely populated but vulnerable due to its proximity to the earthquake’s epicenter.

Chile, located along a major tectonic boundary, has a long history of devastating quakes, including the 1960 Valdivia earthquake — the strongest ever recorded.
