Scientific paper

Rayleigh-wave group velocities have been measured along 11 paths on the African continent, north of the equator. The results lead to a division of this part of the continent into three regions: cratonic areas, non-cratonic areas (``mobile zones''), and a region located to the east of the meridian 31°E (Red Sea neighbourhood, Ethiopia, Djibouti). The highest velocities are found beneath the cratonic areas, at ~ 200 km depth (~ 5%). At greater depths, the ``mobile zones'' exhibit higher velocities than the cratonic regions, but the difference is not as marked (~ 2%) and the resolution is poor. Velocities in the eastern region are similar to those found under young oceanic regions.
