Specifically, PKP waves are P-waves that have traveled through the Earth's mantle and core, and arrive at the surface at a variety of speeds depending on how far they traveled through these layers.

A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that ...
