Abstract
MCKENZIE et al.1 have proposed a pole position and rotation angle to describe the opening of the East African Rift Valleys. On the basis of this rotation, they expect extensions of about 30 km in Kenya and 65 km in northern Ethiopia to have taken place. It follows that the mean relative motion of the two plates in Kenya should have been in a direction of 124° east of north. Interpretation of the gravity anomalies from the Kenya Rift provides some confirmation of the hypothesis.
