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, about 600 meters high. Pico Monumento, a remarkable peak in the form of a slightly inclined cylinder, rises from the west coast. 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 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 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. Pyroclastic flows are a common and devastating result of some volcanic eruptions. ... The Holocene Epoch is a geologic period that extends from the present back about 10,000 radiocarbon years. ... 1961 was a common year starting on Sunday (link will take you to calendar). ...
From 1890 to 1896, Trindade was occupied by the United Kingdom, until an accord with Brazil was reached.
There is a small settlement in the south on Enseada dos Portugueses, supporting a garrison of the Brazilian Navy, 32 strong.

The islands of Trindade and Martim Vaz (also called Martin Vaz), which are located 715 km East of Vitória in the Southern Atlantic Ocean, belong to the Brazilian state of Espírito Santo.

The Trindade and Martin VazIslands were discovered in 1502 by Portuguese navigators, and, along with Brazil, became part of the Portuguese ultramarine domain.
Trindade is a small, deserted, rocky island located in the middle of the South Atlantic Ocean, between the Brazilian coast and the African continent, more than six hundred miles off the coast of Bahia.
The UFO came toward the island at high speed, hovered briefly over a peak, disappeared behind it for a short time, and appeared again to move away toward the sea.
