P and S waves cause the rocking motion of the earth. 3. L or Surface Waves reach the earth's surface after P and S waves. Surface wave travels with a lower velocity than the other two around the surface of the earth. Surface wave is very destructive. There are two types of L waves: (i) Raileigh Waves (ii) Love Waves. Raileigh waves are characterised by the motion of particles in elliptical orbits in the plane of propagation. In the second kind of waves i.e. love waves, the motion of particles is horizontal and at 90Â° angle of the direction of their movement.
