The shallow refraction seismic is widely used in engineering geology exploration, because this method may ascertain the velocity of the refractionsurface.

The surface wave is treated as interference wave in oil seismic prospecting, however, the Rayleigh wave, like the refraction and reflection waves, contains the information of underground medium.
