n: transverse or longitudinal seismic waves transmitted in the interior of an elastic solid or fluid and not related to a boundary surface.

primary or compression wave. A seismic body wave that involves particle motion, alternating compression and expansion. It is the fastest seismic wave.

secondary wave, shear wave, transverse wave. A seismic body wave that involves particle motion from side to side, perpendicular to the direction of wave propagation. S-waves are slower than P-waves and cannot travel through liquid.
