The split in the African continent is a geological process that is currently underway. It is called the EastAfrican Rift, and it is adivergenttectonic plate boundary where the African Plate is in the process of
Geologists say that the growing tear has led to renewed questions about the African continent splitting in two in millions of years. Currently, the Eastern African Rift Valley stretches over 3,000 km from the Gulf of Aden in the north towards Zimbabwe in the south, dividing the African plate ...
While ScS splitting observations have already revealed lowermost mantle anisotropy beneath parts of North America (Nowacki et al., 2010), the geographical coverage of ScS phases beneath the continent is imperfect, and this coverage can be augmented by considering SK(K)S phases. Furthermore, recent...

The Central Iran micro-continent (CIMC) and the Lut block (Fig. 1) were accreted onto the Eurasian margin in the late Triassic (Stöcklin, 1968, Ricou, 1994) following the closure of the Paleotethys oceanic realm since the Cretaceous at a velocity of 15–30 mm/yr (McQuarrie et al.,...
This gave rise to the East African orogeny spanning across Eastern Africa, Madagascar, southern India, Sri Lanka, and coastal Antarctica. In Madagascar, the continent-continent collision was accommodated by crustal thickening and uplift, and the development of near-vertical shear zones [Stern, 1994]...
