Several interesting features of the crust to upper mantle structure beneath the Northwest Pacific Basin were revealed by a seismic explosion experiment conducted during the DELP cruises in 1986. A large lateral heterogeneity was found both in the configuration of the crust/mantle structure and in the sub-Moho lithosphere. The data from the long range explosion experiment along the WSW-ENE survey line do not support the speculation of large scale anisotropy in this region. The lateral heterogeneities in the crust/mantle structure are indicated by variations of the velocity gradients within oceanic layer 3 and in the velocity transitions from layer 3 to the upper mantle. Wide-angle reflections from inside the sub-Moho lithosphere are clearly ...
