Teleseismic event recordings from regional seismic arrays in               the western US contain travel-time information can be used to                   image upper mantle velocity structure beneath much of the western               US.  The seismic inversions and models of other workers and                     results shown in this proposal show that the upper mantle is                    strongly heterogeneous beneath each array investigated.  These                  upper mantle structures are thought to be fundamentally related to              present-day tectonic activity, yet the relationships are not well               understood.  The work proposed offers an opportunity to vastly                  improve understanding of seismic structure beneath the western US,              and it should improve general understanding of the dynamics of                  continental deformation.
