Velocity of Detonation, Rock P-Wave Velocity, and Crater Effect in Blasting
, 2023 This article examines the relationship between the velocity of detonation (VOD) of explosives and the p-wave velocity of rocks. The correlation between these two parameters plays a significant role in the utilization of explosive energy in rock blasting.

Low P‐wave velocity at the base of the mantle
Geophysical Research Letters, 1993 A tool for investigating P‐wave (VP) structure at the base of the mantle is presented. SKS waves at distances around 107° are incident upon the core‐mantle boundary (CMB) with a slowness that allows for coupling with diffracted P‐waves (Pd) at the base of the mantle. The P‐wave diffraction occurs at both the SKS entrance and exit locations of the outer
