We develop ray-based and ray-free body-wave traveltime tomography methods to invert isotropic and anisotropic (azimuthal/radial anisotropy) velocities.
We develop a 2-D/3-D hybrid method that interfaces the spectral-element method (SEM) with the frequency-wave number (FK) technique to model the propagation of teleseismic plane waves beneath seismic arrays.
