A 6.3 magnitude earthquake struck off the southern coast of Argentina on Sunday, the US Geological Survey said, but there were no reports of injuries or damages. The quake was centered about 220 miles (355 km) south-east of Ushuaia, Argentina, at a depth of 6.2 miles (10 km), USGS said. It struck at 8 am local time (1200 GMT).

No tsunami warnings were issued by the West Coast and Alaska Tsunami Warning Center or the Pacific Tsunami Warning Center. "The quake was not felt in Ushuaia and there are no victims or damages," Hector Varela, an Argentine civil defence official told the Telam state-run news agency.
