We perform adjoint waveform tomography to reveal the P-wave velocity structure of the crust and uppermost mantle in Alaska by using common-source double-difference traveltime data. Our underlying forward modeling tool is a 3D seismic-wave solver called SPECFEM3D_GLOBE. We select ∼13,000 high-quality...
