S waves are transverse waves, meaning that the oscillations of an S wave's particles are perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress. Therefore, S waves cannot propagate in liquids with zero (or very low) viscosity ; however, they may propagate in liquids with high viscosity.
