Local slab penetration into lower mantle controls deep-focus seismicity and Changbaishan volcanism in northeast China

The file contains the P-wave velocity model for the manuscript entitled " Local slab penetration into lower mantle controls deep-focus seismicity and Changbaishan volcanism in northeast China". The P wave velocity model is stored in Vp.xyz, it contains five columns, which are longitude, latitude, depth (unit: km), velocity values (unit: km/s) and velocity perturbations relative to the initial model, respectively.
