a seismic wave that travels through the interior of Earth; the two types are P waves and S waves

A seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are examples. Each type of wave shakes the ground in different ways.

a vibration from an earthquake that travels deep underground

A seismic wave that can travel through the interior of the earth. P-waves and S-waves are body waves.
