SANTIAGO, Chile: A magnitude 7.8 earthquake struck the Drake Passage, a stretch of water located between the southern tip of South America and Antarctica on Friday, prompting emergency authorities to issue a tsunami warning.

The earthquake struck just before 5:30 p.m. local time (2030 GMT) at a depth estimated at 10 km. the United States Geological Survey said.

Chile’s SHOA marine authority and the Pacific Tsunami Warning Center issued a precautionary tsunami alert for the country’s Antarctic territory and authorities asked people to evacuate the beaches.

The Pacific Tsunami Warning Center and Chile’s SHOA marine authority withdrew the warnings around an hour later.

The deep waters and rough, windy seas of the Drake Passage mean tsunami waves are less likely to intensify before hitting land.
