Raivavae is a
volcanic island that culminates with Mont Hiro at an altitude of 437 meters. Its land area is 16 km^2. It is surrounded by a fairly large lagoon, but smaller than that of
Tubuai. The surrounding
coral reef comprises twenty-eight motu (islets). It is 630 km southeast of
Tahiti. Raivavae lies in the Cook-Austral volcanic chain, a series of
submarine volcanoes and volcanic islands that stretches along the south of the
Pacific Plate. The central island of Raivavae was formed from a
hotspot on the Pacific Plate, whose
magma production ended about 6.5 million years ago. The main island has four villages: Anatonu on the north coast, Rairua and Mahanatoa on the west coast, and Vaiuru on the east coast. The native language of Raivavae is a variant of the
Austral language called Reo Raivavae. ==Administration==
