Bathymetric map of Central Indian Ridge.
The Central Indian Ridge (CIR) is a divergent tectonic plate boundary between the African Plate and the Indo-Australian Plate, traversing the western regions of the Indian Ocean. The northern section of the CIR is also called the Carlsberg Ridge.
The CIR extends northward from a triple junction near the island of Rodrigues (the Rodrigues Triple Point) to a junction with the Owen Fracture Zone.
