WASHINGTON: Two strong earthquakes 40 minutes apart rocked the remote South Orkney Islands in Antarctica on Sunday, experts from the US Geological Survey said.

The epicentre of the first, a magnitude 6.5 temblor, was at a depth of 10 kilometres (six miles), some 464 kilometres west of Coronation Island, the USGS said. No destructive tsunami was created, according to a US-based warning centre.

The quake occurred at 1340 GMT, and about 40 minutes later the region was struck by an aftershock measured at 6.2, according to USGS.
