Ascension Island is an isolated volcanic island, 7°56′ south of the Equator in the South Atlantic Ocean. It is about 1,000 miles (1,600 km) from the coast of Africa and 1,400 miles (2,300 km) from the coast of Brazil and has a surface area of 98 square kilometers. It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around 800 miles (1,300 km) to the southeast. The territory also includes the sparsely populated Tristan da Cunha archipelago, 2,300 miles (3,700 km) to the south, about halfway to the Antarctic Circle.
Named after the day of its recorded discovery, the Ascension of Jesus, Ascension Island was an important safe haven and coaling station to both mariners and commercial airliners back in the days of international air travel by flying boats.
Ascension is unusual among oceanic islands in having a high proportion of pyroclastic deposits relative to lava flows (approximately 40:60 based on exposure).
The central and eastern parts of the island predominantly comprise pyroclastic deposits (both mafic and silicic) and trachyte lava flows and domes.
The rest of the island predominantly comprises scoria cones and mafic lava flows, some of which have a thin veneer of pyroclastic deposits.
