Answer:
Although surface waves travel more slowly than S-waves, they can be much larger in amplitude and can be the most destructive type of seismic wave. There are two basic kinds of surface waves: Rayleigh waves, also called ground roll, travel as ripples similar to those on the surface of water.
Explanation:
Rayleigh waves (which are a type of surface wave) produce the largest amplitude and so most severe ground movements during earthquakes. Surface waves produce the most severe ground movements. They produce movements similar to waves in the water, where the water's particles move in a pattern that is almost circular
