Fig. 3

Checkerboard resolution test for the entire Kinki region. Input models: a 0.5° by 0.5° horizontal anomaly sizes of the isotropic velocity model, b anisotropic model of anomaly size 0.5° by 0.5° and fast polarization axes that are oriented perpendicular to each other (north and east). c and e Show the recovered velocity model (in a) at 3.5 and 6 km depth slices, respectively. The color bar (in percent) represents the isotropic velocity perturbation with respect to the reference velocity model, d and f show the recovered anisotropic model (in b) at 3.5 and 6 km depth levels, respectively
