Chagos-Laccadive Ridge

The Chagos-Laccadive Ridge on the upper left side of the picture

The Chagos-Laccadive Ridge (CLR), also known as Chagos-Laccadive Plateau^[1], is a prominent volcanic ridge and oceanic plateau extending between the Northern and the Central Indian Ocean. The CLR extends northward for approximately 2350 km from 9° S at the southern end of the Chagos Archipelago to 14° north around the Adas Bank. The islands of Chagos, the Maldives and the Lakshadweep are the above-water parts of the Chagos-Laccadive Ridge.^[2]

The vast Chagos-Laccadive Ridge was formed by the Réunion volcanic hotspot along with the southern part of the Mascarene Plateau. Both plateaux are volcanic traces of the Réunion hotspot.^[3] Although the Chagos-Laccadive 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 6°00′S 71°20′E / 6°S 71.333°E / -6; 71.333.^[4]
