Abstract : This report describes a range of studies which have been directed at improved delineation of structure at regional scales which can be used in calibrating seismic information from regional or teleseismic sources. The first two sections describe the development of fine-scale three- dimensional models for the crust and lithosphere incorporating a broad class of seismic information and the extension of such procedures to include anisotropy. The next part develops a new theoretical approach which should allow direct computation of surface wave fields in 3-D models. The final section presents a regionalized model for the upper mantle based on tectonic characteristics derived using teleseismic information which provides a representation of the upper mantle for the whole globe.
