Emergency officials on Friday lifted a series of tsunami warnings they had briefly issued following a 7.8-magnitude earthquake that struck the Drake Passage, a stretch of water between the southern tip of South America and Antarctica.
The Pacific Tsunami Warning Center and Chile’s SHOA maritime authority briefly issued tsunami warnings after the earthquake, whose depth was estimated at 10 km by the United States Geological Survey, but lifted those warnings about an hour later.
Chilean authorities warned of possible impacts on the military bases of Prat and O’Higgins, at the tip of Antarctica, and at Cape Horn, at the southernmost tip of Tierra del Fuego.

The earthquake struck just before 5:30 pm (local time) and, within just over an hour, authorities lifted tsunami warnings.
The deep waters and rough, windy seas of the Drake Passage mean that tsunami waves are less likely to intensify before reaching land.
