Seismic tomography with full waveform inversion

Caption

Azimuthal anisotropy (black dashed lines showing the fast direction of wave speeds) in the mantle at 200 km depth plotted on top of vertically polarized shear wave speed perturbations (dVsv) after 20 iterations based on global azimuthally anisotropic adjoint tomography. The maximum peak-to-peak anisotropy is 2.3%. Red and blue colors denote the slow and fast shear wave speeds with respect to the mean model which are generally associated with hot and cold materials, respectively.
