Answer:
S waves travel typically 60% of the speed of P waves. They are typically more damaging than the P waves because they are several times higher in amplitude. Earthquakes also produce surface waves which may cause motion perpendicular to the surface or parallel to the surface.

- Do P or S waves cause more damage?
- An earthquake also causes secondary or shear waves, called S waves. These travel at about half the speed of P waves, but can be much more destructive. S waves move the earth perpendicularly to the direction the wave is traveling.
