Bassas da India is an uninhabited, roughly circular atoll that is part of the French Southern and Antarctic Lands. Located in the southern Mozambique Channel, about halfway between Mozambique and Madagascar (about 385 km (239 mi) further east) and around 110 km (68 mi) northwest of Europa Island, the rim of the atoll averages around 100 m in width and encloses a shallow lagoon of depth no greater than 15 m. Overall, the atoll is about 10 km (6 mi) in diameter, rising steeply from the seabed 3000 m below to encircle an area (including lagoon) of 80 km2 (31 sq mi). Its Exclusive Economic Zone (EEZ), 123,700 km2 (47,761 sq mi) in size, is contiguous with that of Europa Island.
The atoll consists of ten barren rocky islets, with no vegetation, totalling 0.2 km² (.077 sq mi) in area. Those on the north and east sides are 2.1 to 3 m high, while those on the west and south sides are 1.2 m high. The reef, whose coastline measures 35.2 km (22 mi), is completely covered by the sea from three hours before high tide to three hours afterward. The region is also subject to cyclones, making the atoll a long-time maritime hazard and the site of numerous shipwrecks.
The Bassas da India was first recorded by Portuguese explorers in the early sixteenth century as the "Baixo da Judia" ("Jewess Shoals"). The Judia ("Jewess", for the ancestry of its owner Fernão de Loronha) was the Portuguese ship that discovered the feature by running aground on it in 1506. The name became "Bassas da India" due to transcription errors by cartographers. The Santiago broke up on the shoal in 1585.
It was rediscovered by the Europa in 1774, whence the name "Europa Rocks". The Malay was lost 27 July 1842 on the Europa Rocks.
In 1897, the shoal became a French possession, later being placed under the administration of a commissioner residing in Réunion in 1968. Madagascar continues to claim sovereignty over the islands.
Mooring at Bassas da India requires a permit from the French Government. Fishing without such a permit may result in the boat being expelled or even confiscated. Several illegal tourism charters departing from Mozambic or South Africa have been seized since 2013 by French navy.
