1. Seismic Waves Types of Wave Propagation

2. Body Waves P & S Waves P and S waves are often called body waves because they propagate outward in all directions from a source (such as an earthquake) and travel through the interior of the Earth.

3. P Compressional Primary Wave Body wave Longitudinal

4. S Shear Secondary Wave Body wave Transverse

5. Body Waves P & S Waves In the animations shown here, the P and S waves are shown propagating horizontally, parallel to the Earth’s surface.

6. Surface Waves Rayleigh & Love Waves Love and Rayleigh waves are surface waves and propagate approximately parallel to the Earth’s surface. Although surface wave motion penetrates to significant depth in the Earth, these types of waves do not propagate directly through the Earth’s interior.
