| Short Description | WUS256 is a model of radially anisotropic crustal and upper mantle seismic structure of the western United States from adjoint waveform tomography. It is based on a multiscale inversion strategy with 8-stages and many iterations (256). WUS256 provides significantly improved waveform fits in the period band 20-120 seconds relative to the starting and several other models. | ||
