Another example of waves with both longitudinal and transverse motion may be found in solids as Rayleigh surface waves (named after John W. Strutt, 3rd Baron Rayleigh who first studied them in 1885). Love, the man who predicted this type of seismic wave in 1911. are contained in the Nova video "(To view files, click on the file
They cause a rolling motion along the surface of the ground, similar to the movement of ocean waves. A slight elastic anisotropy gives rise to an azimuthal dependence of the phase velocities of both Love and Rayleigh waves of the form c (ω, θ) = A 1 (ω) + A 2 (ω) cos 2θ + A 3 (ω) sin 2θ + A 4 (ω) cos 4θ + A 5 (ω) sin 4θ where ω is the angular frequency and θ is the azimuth of the wave‐number vector.

This a relatively slow type of fading, that could occur in an indoor propagation environment.

Rayleigh waves are generated by the interaction of P- and S- waves at the surface of the earth, and travel with a velocity that is lower than the P-, S-, and Love wave velocities.

Wave propagation and particle motion characteristics for the P, S, Rayleigh and Love waves are illustrated in Figures 1-4. to learn about global and regional seismicity.IRIS is a consortium of over 120 US universities dedicated
The Doppler shifts are chosen to lead to a Doppler spread of 1 Hz.
R Rayleigh Surface waves
However, the particle motion of surface waves is larger than that of body waves, so the surface waves tend to cause more damage.
the Love waves is also dependent on frequency, with lower frequencies
