In the two areas of Lobito-Benguela and Mossamedes, deposits of distinct Holocene, mid-Würmian, Eemian and Mindel-Riss interglacial shorelines were radiometrically dated using 14C and 230Th/234U and 231Pa/231U ratios. Deposits of different ages were found on the same terraces: the morphology of these terraces is the result of repeated erosion at different times by successive sea levels at similar elevations. The average rate of uplift clearly increased since the Riss; the Holocene appears to be a period of markedly increased epeirogenic activity. Also vertical movement appears more intense in the Lobito-Benguela area than near Mossamedes. The intensity of uplift appears to be associated with epicentres oriented towards the west-southwest, that is parallel to the axis of the Walvis ridge; the direction is outlined by diverse Mesozoïc effusive volcanic centres.
