P′ and the Earth's Core

Abstract

The velocity of longitudinal seismic waves in the Earth increases with depth down to the discontinuity separating mantle and core, at a depth of about 2900 km., where it drops from 13.7 to about 8 km./sec. Within the core, the velocity has usually been calculated as increasing gradually to about 11.5 km./sec. at the centre.
