An S wave, also known as a secondary wave or shear wave, is a type of seismic wave that moves more slowly than a primary wave (P wave) and is characterized by its transverse motion. This means that the particles of the medium through which the S wave travels move perpendicular to the direction of the wave's propagation. S waves cannot travel through liquids, which is why they do not pass through the Earth's liquid outer core. They are typically the second wave to be recorded by a seismograph after the faster P waves. S waves are more destructive at the surface than P waves because they have a greater amplitude and cause more lateral shaking.

a transverse earthquake wave that travels through the interior of the earth and is usually the second conspicuous wave to reach a seismograph. Expand. Also called secondary wave. Compare L wave, P wave. S wave in Medicine.
