Rayleigh wave

{
  "id": "MLC-T-OAG-004433",
  "term": "Rayleigh wave",
  "field": "Oil and gas",
  "definition": "A type of surface wave that travels along the free surface of a solid, causing particles to move in an elliptical, retrograde motion in the vertical plane. In seismic exploration, these waves are a component of ground roll, a form of coherent noise that can obscure deeper reflections. Rayleigh waves have lower velocities than body waves (P-waves and S-waves) and their amplitude decreases exponentially with depth.",
