Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
It is caused by a strain on the fault lines of the Earthâs crust. When the energy of the strain is released, similar to a rubber band snapping, the earthquake occurs. At the Earth's surface, earthquakes cause a shaking or displacement of the ground and sometimes cause the ground to break apart and change shape.
