Pico Basilé

Basile, Pico

Vulcano a scudo · Equatorial Guinea · 2999 m

Santa Isabel volcano occupies the northern end of Bioko (Fernando Poo) Island in this NASA Landsat view with north to the upper left. A large escarpment cuts the northern side of the 3,007-m-high volcano, whose summit is cut by regional NE-SW-trending faults. Numerous scoria cones are present, many of which lie along the same tectonic trend. Santa Isabel is the only Bioko Island volcano with reported historical eruptions, although they are poorly documented. The brown area along the northern coast is the capital city of Malabo.

Sintesi geologica

Pico Basilé is the largest and highest of three basaltic shield volcanoes forming Bioko Island. Lying on the continental shelf along the Cameroon Line, this volcano is modified by the same NNE faults as Mt. Cameroon across the Gulf of Guinea on the mainland. It contains numerous satellitic cinder cones and is the only Bioko Island volcano with recorded eruptions, although they are poorly documented. Three eruptions, during the late-19th and early-20th centuries, have been reported from SE flank vents.

Riassunto in inglese

Pico Basilé, located on the island of Bioko, is the tallest mountain of Equatorial Guinea. With an elevation of 3,011 metres, it is the summit of the largest and highest of three overlapping basaltic shield volcanoes which form the island. From the summit, Mount Cameroon can be seen to the north-east. Pico Basilé lies close to the city of Malabo. The very top is used as a broadcast transmitting station for RTVGE and microwave relay station for various communication networks.
