Trindade and Martim Vaz ( Portuguese Arquipélago de Trindade e Martim Vaz ) are a Brazilian group of islands in the Atlantic Ocean , about 1,200 kilometers east of Vitória . The names Trinidad and Martin Vas are also used . The archipelago belongs to the state of Espírito Santo and is considered part of the capital Vitória, but does not belong to any of the administrative regions or bairros of the city.
Trindade is the largest island with 10.3 km² and is 47 km west of the significantly smaller Martim Vaz archipelago . Except for the Enseada dos Portugueses post on Trindade, which is manned by 32 soldiers from the Brazilian Navy, the islands are uninhabited. The highest point is at 620 m above sea level .
The islands are of volcanic origin and are associated with the phenomenon of a mantle plume . The term Trindade hotspot is also used accordingly .
history
