An earthquake with a 6.4 magnitude has struck south of an Argentinian resort town, the U.S. Geological Survey says.
The quake hit at 2.54 am local time this morning and was centred in the ocean 194 miles south southeast of Ushuaia, Tierra del Fuego.
It is thought to have been relatively shallow, at a depth of 6 miles.
There are currently no reports of casualties or damage caused by the shock, which struck a perilous length of water known as the Drake Passage.
The Tierra del Fuego archipelago, dubbed the ‘End of the World’, is the southern most tip of South America.
