South Sandwich Islands earthquake September 4, 2017

South Georgia and the South Sandwich Islands (SGSSI) is a British overseas territory in the southern Atlantic Ocean. It is a remote and inhospitable collection of islands, consisting of South Georgia and a chain of smaller islands known as the South Sandwich Islands. South Georgia is 165 km (103 miles) long and 1 to 35 km (1 to 22 miles) wide and is by far the largest island in the territory. The South Sandwich Islands lie about 700 km (430 miles) southeast of South Georgia. The territory's total land area is 3 903 square kilometers (1 507 sq mi). The Falkland Islands are about 1 300 km (810 miles) north-west from its nearest point.

There is no permanent population on the islands. The present inhabitants are the British Government Officer, Deputy Postmaster, scientists, and support staff from the British Antarctic Survey who maintain scientific bases at Bird Island and at the capital, King Edward Point, as well as museum staff at nearby Grytviken.
