Answer:
Seismic S waves consist of shear wave propagation, where the particles move perpendicular to the propagation direction of the disturbance. These types of waves can be propagated inside the earth.
Its speed is less than that of the primary waves. Because of this, they appear on the ground somewhat after the others. These waves are the ones that generate the oscillations during the seismic movement and the ones that do most of the damage. They do not move through liquid elements.
