2D view
Inland, it goes from the Cameroon Ngaoundere Plateau at N-E, Oku Volcanic Field (sadly reknown for the dangerous CO2-filled lakes Nyos & Monoun), Western High Plateau & the 4040 m high Mount Cameroon. All are still volcanically active.
Fig. 2 - S1 (13-22.04.2018) - These are remnants of a failed rift arm when South America parted away from Western and Southern Africa.
3D view
Fig. 3 - It includes the islands of Bioko (32 km away from mainland, topped by a 3012 m active volcano) and Príncipe (330 km SW of Mt Cameroon, 947 m high extinct volcano over a 3000 m deep seafloor.
3D view
Fig. 4 - São Tomé lies 510 km SW of Mt Cameroon, its 2024 m high extinct summit rises from the -3000m seafloor. Annobón is even 200 km further, only 600 m high but above a 500 m deeper floor.
