Files in this Data Supplement:

• Animation 1 - Animation 1. 3D representation of isocontours of positive-velocity anomalies beneath Africa (shaded red). African coastline and 0- to 100-km horizontal tomography slice plotted for reference. The anomalies are isocontoured between 1.2% and 2.4%, at intervals of 0.1%, and the results are presented as a time series. File size is 15.3 MB.
• Animation 2 - Animation 2. A perspective view of the depth-normalized, fast-velocity anomalies beneath Africa, isocontoured at +1.9%. The time series represents varying azimuth, viewed from the southwest. File size is 15.4 MB.
