The Ethiopian Rift Valley began to form during the late Oligocene to early Miocene epochs, around 30 million years ago. This geological feature is the result of tectonic processes associated with the divergence of the African tectonic plate and the Somali plate, which created a rift that continues to evolve today. The rifting process has led to the formation of various geological features, including lakes, volcanoes, and unique ecosystems in the region.
