WebOct 3, 2011 · Rayleigh waves are formed under the conditions where multiple reflections of P and S waves sum up to make a bigger, slower (group velocity) wave which expands cylindrically. Also, Rayleigh waves are "surface waves", which means that they only propagate at and a few hundred km below the surface (they get weaker with depth). May …
