Seismic Waves

Seismic Waves. Types of Wave Propagation. 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.

  1. Seismic Waves Types of Wave Propagation

  2. Body WavesP & 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 CompressionalPrimary Wave Body wave Longitudinal

  4. S Shear Secondary Wave Body waveTransverse

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

  6. Surface WavesRayleigh & 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.
