Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
Most destructive quakes, however, are caused by dislocations of the crust. The crust may first bend and then, when the stress exceeds the strength of the rocks, break and snap to a new position. In the process of breaking, vibrations called seismic waves are generated.
