The small island of Trindade lies at the eastern end of an E-W-trending chain of submarine volcanoes and guyots extending about 1100 km 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 Vitória-Trindade Ridge. Trindade is a dissected volcanic island with numerous phonolitic lava domes and steep-sided volcanic plugs. The youngest volcanism, at Vulcao de Paredao on the SE tip of the island, constructed a pyroclastic cone with lava flows that are no older than 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 form an irregular shoreline and offshore islands. Smaller volcanic centers of the latest volcanic stage are found in the Morro Vermelho area in the south-central part of the island.

The Global Volcanism Program is not aware of any Holocene eruptions from Trindade. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Trindade page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The rugged coast of the small island of Trindade reflects dissection of numerous phonolitic lava domes and steep-sided volcanic plugs. Trindade lies at the eastern end of an E-W-trending chain of submarine volcanoes and guyots extending about 1100 km from the continental shelf off the Brazilian coast. The youngest volcanism, at Vulcao de Paredao on the SE tip of the island, constructed a pyroclastic cone with lava flows that reached the sea.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
