Uppermost mantle seismic Pn-velocity in the continental China and its tectonic implications

In this study, we construct a high-resolution Pn -velocity model in the continental China through a new tomographic scheme that simultaneously inverts event epicenter location and Pn-velocity, and accurately accounts for the Pn propagation effects of irregular crustal thickness variation. The inversion integrates a combined dataset of 32427 absolute Pn travel times and 62431 interstation Pn differential travel times manually picked from the recordings of 2989 stations in and around the continental China
