Rifting of the eastern part of the East African Rift System was thought to have begun several million years before its western counterpart. Reconstructions of drainage development, combined with dating of rift-related volcanic activity, suggest that rifting in the western branch may instead have begun at the same time as in the eastern branch. 
Genesis of the East African Rift System
The East African Rift System (EARS) started in Late Oligocene to Early Miocene time and gradually propagated southwards from the Afar Depression, beginning in the Middle Miocene. The hot, low-density
The Western Branch of the East African Rift : A Review of Tectonics , Volcanology and Geothermal Activity
The East African Rift System (EARS) is a classic example of continental rifting and provides an excellent framework to study extensional magmatism and the evolution of several central volcanic
The offshore East African Rift System: Structural framework at the toe of a juvenile rift
The Cenozoic East African Rift System (EARS) extends from the Red Sea to Mozambique. Here we use seismic reflection and bathymetric data to investigate the tectonic evolution of the offshore branch
Uplift of Africa as a potential cause for Neogene intensification of the Benguela upwelling system
The Benguela current cooled over the past 12 million years. Numerical modelling suggests that uplift of parts of Africa during this time enhanced coastal low level winds and promoted greater
Birth of the East African Rift System: Nucleation of magmatism and strain in the Turkana Depression
The Turkana Depression of northern Kenya and southern Ethiopia contains voluminous plume-related basalts that mark the onset of the Paleogene–recent East African Rift System (EARS) at ca. 45 Ma.
Lithospheric Controls on the Rifting of the Tanzanian Craton at the Eyasi Basin, Eastern Branch of the East African Rift System
Continental rifts most often nucleate within orogenic belts. However, some studies in the East African rift system have shown that continental rifts can also develop within cratons. This work

We propose a new kinematic framework for the East African rift system linking the development of the Eastern and Western rifts via stress transmission across the Archean Tanzania craton. The proposal
Tectonic development of the northern Taiizaiiian sector of the East African Rift System

Changes in African topography driven by mantle convection
Africa’s topography is characterized by large-scale uplifted domes and subsided basins. Numerical simulations of mantle flow suggest that high topography along Africa’s eastern margin formed as a

The growth of East Africa's high topography during the past 30 million years cannot be explained by typical mountain-building processes. Numerical modelling shows that much of this topography formed
Tectonic Uplift and Eastern Africa Aridification
TLDR
This work suggests that the uplift of eastern African topography led to a drastic reorganization of atmospheric circulation, engendering the strong aridification and paleoenvironmental changes suggested by the data.
