Phase velocity of fundamental mode and up to the fourth overtone Rayleigh waves are determined using the Mode Branch stripping technique [H. J. Van Heijst and J. H. Woodhouse, Geophys. J. Int. 131, 209 (1997)], involving cross-correlation of single-mode branch synthetics with long-period seismograms. Phase velocity maps of these fundamental and overtone Rayleigh wave data are presented in H. J. Van Heijst and J. H. Woodhouse [Geophys. J. Int. 137, 601 (1999)].

We account for the effects of topography and crustal thickness variation using the model CRUST5.1 [W. D. Mooney, C. Laske, G. Masters, J. Geophys. Res. 103, 727 (1998)]. Seismic velocity variations are parameterized using 21 vertical spline functions and spherical harmonics up to degree 20. The inversion involves two steps: earthquake source relocation, and damped least-squares inversion for shear velocity structure. We iterate upon these steps until maximum variance reduction is obtained. The damped least-squares inversion for model parameters involves the computation of the eigenvalue decomposition, allowing us to determine model resolution. We do not apply smoothness constraints to the model.
