Sound between the Falkland Islands

The Falkland Sound (lang es) is a sea strait in the Falkland Islands. Running southwest northeast, it separates West and East Falkland.

The sound was named by John Strong in 1690 for Viscount Falkland, the name only later being applied to the archipelago and its two largest islands. The Spanish name "Estrecho de San Carlos" refers to the ship San Carlos which visited in 1768; confusingly the English name "San Carlos Water" is a much smaller inlet on East Falkland and gives its name to San Carlos, Port San Carlos and the San Carlos River. Captain John Strong of the Welfare made the first recorded landing on either of the main islands (West and East Falkland) on 29 January 1690, at Bold Cove (near Port Howard) just off Falkland Sound.

About 400 million years ago the land that became the Falkland Islands and Antarctica's Ellsworth Mountains, which had been part of Gondwana, broke from what is now Africa and drifted westwards relative to Africa. During the mid Jurassic period (about 170 million years ago) the land fragment that was to become East Falkland and the land fragment that was to become West Falkland rotated about 120° relative to each other. As a result, the fold lines in West Falkland run almost south west to north east, parallel to the Sound. Those in the northern part of East Falkland run east west, forming the eastern part of northern entrance to the Sound and bordering on the northern banks of San Carlos Water. The boundary between these two land fragments, the Falkland Sound Fault, lies close to and parallel with the western shore of the Sound. Lafonia (the southern half of East Falkland), which is a much newer formation, has no folds. It is believed that at times during the Pleistocene era, the seabed was some lower than the present time–sufficient for the sound to be bridged.
