Bassas da India

Bassas da India is an uninhabited, roughly circular French atoll that is part of the French Southern and Antarctic Lands. Located in the southern Mozambique Channel, about halfway between Mozambique and Madagascar and around 110 km northwest of Europa Island, the rim of the atoll averages around 100 metres in width and encloses a shallow lagoon of depth no greater than 15 m. Overall, the atoll is about 10 km in diameter, rising steeply from the seabed 3,000 metres below to encircle an area of 80 km2.
