S-wave

S-wave: An elastic body wave where particles oscillate perpendicular to the path where the wave develops. S-waves are created by the majority of ground seismic sources, but not by air guns.

P-waves which impinge on an interface at non-normal incidence can generate S-waves, which in that case are called converted waves. Commonly used in geophysics.
