Animations Illustrating Simple Wave Propagation Concepts

These animations show how various types of waves are propagated during an earthquake. Users can see how P-waves travel at the surface, how they are reflected and refracted as they travel further from their source, and how multiple reflections can combine to create a surface wave. There is also an animation showing how S-waves were amplified by reflections from the Moho during the 1989 Loma Prieta earthquake that struck San Francisco.
