How does the type of ground affect earthquakes

As seismic waves travel through the ground, they move faster through hard rock than soft soil. When waves transition from hard to soft earth, they increase in amplitude (or size). A bigger wave causes stronger shaking. The same principle also applies to sediment thickness.
