Cameroon line

The Cameroon line (English: Cameroon line ) is a volcanic mountain range in Central Africa. The mountain range extends to the mainland along the border between Cameroon and Nigeria, ranging from the Bay of Bonny in the direction of Lake Chad. Distinctive landscape features are the 4,040 m high Mount Cameroon and the Cameroon Grasslands. In the Gulf of Guinea to the Cameroon line is in the form of islands of São Tomé and Príncipe and the belonging to Equatorial Guinea Bioko, and Annobón ( Pagalu ) away. Next in the southwest include some seamounts to the line.

With the exception of Mount Cameroon volcanoes along the Kamerumlinie rest now. Striking volcanoes in this chain are the Bambouto massif, Manengouba, Oku and the Kupe. Also known are some crater lakes, including the Barombi Mbo, the Bermin Lake and Lake Nyos. In the latter in 1986 a devastating limnic eruption, which called in the surroundings of the lake over 1,200 deaths occurred.

Geologically the Cameroon line is in the range of the Central African shear zone, which extends from the Gulf of Guinea to Sudan and in communication with the Great African grave breach. West of the Cameroon line is the Benue Benue trough or trench, another grave breach. On the origin of the line, there are essentially two theories: The first is based on a relatively slow hotspot, or a plume under the area of which is currently under the Oku massif is located. The other theory explains the origin of tectonic stresses in the movement of the African plate, with a triple point -like structure is said to have formed. Two of the three arms of this structure, while the Mid-Atlantic Ridge, while the third arm to show off the back off towards home.
