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.

n: a blowout preventer that uses shear rams as closing elements.

n: A type of vertical seismic profile in which the source is a shear-wave source rather than a compressional-wave source. Shear waves travel through the Earth at about half the speed of compressional waves and respond differently to fluid-filled rock, and so

n: distortional, equivolumnar, secondary, or transverse wave.

S wave.
