The East African Rift is the most spectacular recent example of an intracontinental rift. It is a true reflection of the dynamics of one or more mantle plumes present under the surface of this region. The NS propagation of the axial valley, from Afar triple junction, diversifies to the North of Tanzania in 2 (3) arms constituting the North Tanzanian Divergence (NTD). The volcanic activity from ~ 6 Ma upwards and the tectonic features of the rifting, have conditioned the sedimentation, climate variability and geomorphology, whose interaction has also led to the peculiar evolution of the landscape, flora and fauna and even the way of life of human groups that have settled the territory. In all, the NTD is a reference of great didactic value, where, in July 2011, the AEPECT (Spanish Association for the Teaching of Geology .) organized the workshop of Earth Sciences: Expedition through the Great Rift.
