Sintesi geologica
The massive steep-sided Mount Cameroon rises above the coast of west Cameroon, overlooking the Bight of Biafra, part of the Gulf of Guinea. The dominantly basaltic-to-trachybasaltic edifice forms a volcanic horst constructed above a basement of Precambrian metamorphic rocks covered with Cretaceous to Quaternary sediments. More than 100 small cinder cones, often fissure-controlled parallel to the long axis of the 1,400 km3 edifice, occur on the flanks and surrounding lowlands. A large satellitic peak, Etinde (also known as Little Cameroon), is located on the S flank near the coast. The first known reported activity was in the 5th century BCE by the Carthaginian navigator Hannon. Additional activity has frequently been reported since about 1800 CE, consisting of moderate explosive and effusive eruptions from both summit and flank vents. A 1922 SW-flank eruption produced a lava flow that reached the Atlantic coast, and a lava flow from a 1999 S-flank eruption stopped only 200 m from the sea. Explosive activity from two vents on the upper SE flank was reported in May 2000.
