A 6.6-magnitude earthquake has struck east of the South Sandwich Islands in the South Atlantic Ocean, according to the United States Geological Survey (USGS).
The earthquake’s epicentre was more than 1,810 kilometres from King Edward Point, a research station on South Georgia Island and is the capital of the British Overseas Territory of South Georgia and the South Sandwich Islands, according to the Indian National Centre for Seismology.
The South Sandwich Islands deal with seismic activity caused by the subduction of the South American Plate beneath the South Sandwich Plate.
The South Sandwich Islands are uninhabited. During the summer they are visited by scientific expeditions.
