The vast Chagos–Lakshadweep Ridge contains a considerable amount of volcanic rock, as does the southern part of the Mascarene Plateau.Although the Chagos–Lakshadweep Ridge is an aseismic ridge, between 1965 and 1970 an unusual, isolated swarm of earthquakes occurred on the west side of the Great Chagos Bank at approximately
The ecoregion is made up of low islands made mostly of coral sand, generally no more than 5 meters above sea level, and surrounded by extensive coral reefs.The islands rest on the Chagos–Laccadive Ridge, an oceanic ridge and plateau, and extend 2,550 km north and south across the equator, from latitude 14º N to 8º S. Lakshadweep lies to the north, 300 km west of India's southwest coast.
The Chagos group is a combination of different coralline rock structures topping a submarine ridge running southwards across the centre of the Indian Ocean, formed by volcanoes above the Réunion hotspot. Unlike the Maldives, there is no clearly discernible pattern in the atoll arrangement, which makes the whole archipelago look somewhat chaotic.
Lakshadweep is the northernmost island group of the exposed undersea mountain range, the Chagos-Lakshadweep Ridge. [35] While there are no conclusive theories about the formation of the atolls, Charles Darwin proposed in 1842 CE that the subsidence of a volcanic island resulted in the formation of a fringing reef, which grew upwards with ...
Diego Garcia is part of the Chagos-Laccadive Ridge, an underwater mountain range [4] that includes the Lakshadweep, the Maldives, and the other 60 small islands of the Chagos Archipelago. The island observes UTC+6 year-round.
Britain struck a deal in October to hand over the Chagos Islands while retaining control of the base on Diego Garcia, the largest island of the archipelago in the Indian Ocean, under a 99-year lease.
National security will be put at risk unless the Chagos Islands are handed over to Mauritius in a deal set to cost the UK taxpayer billions, Sir Keir Starmer said.
The geology of the British Indian Ocean Territory comprises the Chagos Archipelago — the above water portion of the Chagos Bank. Formed from hotspot volcanism, the Chagos Bank was separated from the Nazareth Bank, which is administered by Mauritius, 36 million years ago by activity on the Central Indian Ridge. Aside from plate boundaries, the ...
