Rayleigh wave phase velocity
WebRayleigh wave energy is dispersive meaning that different frequencies travel with different velocities. More specifically, each frequency travels with a phase velocity that is mostly a function of the average shear-wave velocity of the subsurface from the ground surface to the base of particle motion associated with that frequency (wavelength). WebRayleigh-wave dispersion curves from ground roll, and 3) develop stable and efficient inversion algorithms to ob-tain near-surface S-wave velocity profiles. The first two …
