Adams, A. & Nyblade, A., 2011. Shear wave velocity structure of the southern African upper mantle with implications for the uplift of southern Africa (Geophys. J. Int., 186, 808–824).
This erratum corrects a mistake in Adams & Nyblade (2011). Adams & Nyblade (2011) used a two-plane wave inversion to solve for 2-D Rayleigh wave phase velocity maps at periods ranging from 17 to 167 s for southern Africa, which included a solution for average azimuthal anisotropy at those periods. Those phase velocity maps were then inverted for a quasi-3-D shear wave velocity model.
Since the time of the publication of Adams & Nyblade (2011), the authors have found an error in fig. 9, which shows average azimuthal anisotropy at each period in the study. As a result of a plotting error, the per cent velocity variation shown in the original fig. 9 is incorrect. The fast direction of the anisotropy was not affected by this error. The caption for fig. 9 and references to the figure within the text are unchanged, and a corrected version of fig. 9 is now given here (Fig. 1).
Plot showing the fast direction for azimuthal anisotropy as a function of period and per cent change in velocity. At each period, the fast polarization direction is indicated by the direction of the line relative to the north arrow. The position of the line along the y-axis indicates the per cent change in velocity at that period.
