Because Rayleigh waves are surface waves, the amplitude of such waves generated by an earthquake generally decreases exponentially with the depth of the hypocenter (focus). However, large earthquakes may generate Rayleigh waves that travel around the Earth several times before dissipating.

In elastodynamics, Love waves, named after Augustus Edward Hough Love, are horizontally polarized surface waves. The Love wave is a result of the interference of many shear waves (S-waves) guided by an elastic layer, which is welded to an elastic half space on one side while bordering a vacuum on the other side.

What are Love Waves? - Definition from Trenchlesspedia

WebOf the two surface waves, Love waves move faster. Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves. How do Rayleigh waves move? Rayleigh Waves—surface waves that move in an elliptical motion, producing both a vertical and horizontal component of motion in the direction ...
