In relation to seismic body waves, an "S-wave" is a type of transverse wave that travels through the interior of the Earth. When this type of wave is formed, it travels 40% slower than compressional "P-waves", so their effect is recorded secondary to the initial P-wave. Horizontally polarized S waves create a condition in which the ground moves alternately from one side and to the other, perpendicular to the direction of energy propagation. S-waves can travel only through solids because liquids and gases cannot support shear stresses.
