East Africa Rift Thinning Points to a Possible New Ocean
Seismic data reveal the Turkana Rift in East Africa is thinning far more than previously thought, with the crust at the rift center about 13 km thick compared with well over 35 km away, signaling an advanced necking stage toward eventual continental breakup and ocean formation. The process began millions of years ago and will take millions more to unfold, while subsidence and sedimentation here also help preserve an unusually rich fossil record, influencing interpretations of human evolution and past climates.
