Chilean authorities issued a tsunami warning for the country's southernmost region Friday morning and both Chile and Argentina ordered evacuations after a major 7.5-magnitude earthquake struck off the coast of South America.
The US Geological Survey (USGS) said the quake struck in the Drake Passage at a shallow depth of 10 kilometers (6.2 miles), 219 kilometers from the city of Ushuaia in Argentina and a similar distance from the Chilean town of Puerto Williams.
