Cover Picture
3-D rendering of the North American isotropic and radially anisotropic shear wave model SVEMum_NA2 (Research Section 11) in the western US, viewing from the southwest (a and c), and the northwest (b and d). The velocity variations are with respect to the NA regional average. The isosurfaces in a) and b) are drawn at -1.5% and 3% for the slow and fast velocities, respectively. For radial anisotropy (c and d), the isosurface values are -2% and 4%. Green lines at the top of each plot indicate the western US physiographic regions. Thick black line is the plate boundary between the North American and the Pacific plates.
