WebJun 21, 2014 · Surface waves Rayleigh waves Named for John William Strutt, Lord Rayleigh, who mathematically predicted the existence of this kind of wave in 1885. Rolls along the ground just like a wave rolls across a lake or an ocean. Because it rolls, it moves the ground up and down, and side-to-side in the same direction that the wave is moving. Web: Calculations are presented for the description of seismic waves created by the reflection of a spherical shock wave from the surface of the earth. The earth is represented by a homogeneous medium, but the elastic constants vary with the frequency of each Fourier component of the incident pulse in order to reproduce measured dispersion data.
