Excerpt: Trindade and Martim Vaz - The individual islands with their respective locations are given in the following: The small island of Trindade, with an area of 10.3 km, lies at the eastern end of an E-W-trending chain of submarine volcanoes and guyots extending about 1,000 km (620 mi) from the continental shelf off the Brazilian coast. The island lies more than halfway between Brazil and the Mid-Atlantic Ridge near the eastern end of the submarine Vit ria-Trindade Ridge. Trindade is a mountainous, dissected volcanic island with numerous phonolitic lava domes and steep-sided volcanic plugs. The highest summit is Pico Desejado, near the center, 620 meters high. Nearby to the northwest are Pico da Trindade (590 m) and Pico Bonif cio (570 m). Pico Monumento, a remarkable peak in the form of a slightly inclined cylinder, rises from the west coast to 270 m. The youngest volcanism, at Vulc o de Pared o (217 m) on the southeast tip of the island, constructed a pyroclastic cone with lava flows that are no older than the Holocene (Almeida, 1961). Remnants of the crater of the 200 m high cinder cone are still preserved. Lava flows traveled from the cone to the north, where they formed an irregular shoreline and offshore islands. Smaller volcanic centers of the latest volcanic stage are found in the Morro Vermelho (515 m) area in the south-central part of the island. There is a small settlement in the north on Enseada dos Portugueses, supporting a garrison of the Brazilian Navy, 32 strong. The island is the main nesting site of the green sea turtle in Brazil. The Trindade and Martin Vaz Islands were discovered in 1502 by Portuguese navigators lead ...More: http: //booksllc.net/?id=1855209
