Submerged bank

The Saya de Malha Bank (also Sahia de Malha Bank, Modern Portuguese: saia de malha, English mesh skirt) is the largest submerged bank in the world, part of the vast undersea Mascarene Plateau.

Saya de Malha lies northeast of Madagascar, southeast of the Seychelles, and north of the Nazareth Bank, the Cargados Carajos shoals, and the island of Mauritius, and currently falls mostly under International waters. The closest land is the tiny Agaléga Islands (an Outer islands of Mauritius), some 300 km (190 mi) further west, followed by the southern Seychellois island of Coëtivy, some 400 km (250 mi) northwest. Mauritius administers the whole Saya de Malha Bank as a portion of it lies within its Exclusive Economic Zone.

The bank covers an area of 40,808 km² (15,756 sq mi), and is composed of two separate structures, the smaller North Bank (also called Ritchie Bank), and the huge South Bank. If the South Bank were recognized as a submerged atoll structure, it would be the largest of the world, almost three times the size of the Great Chagos Bank, commonly considered the largest atoll structure of the world. Even smaller North Bank would be one of the largest atolls worldwide. The North Bank and the South Bank appear to have different origins, since they are separated by a fault. The South Bank and the Great Chagos Bank were one single feature until about 64 to 69 million years ago, when an ocean ridge opened between them and started pushing them apart.
