Rayleigh velocity
WebSep 10, 2024 · Rayleigh Waves can be used to measure how velocity varies with depth since they are dispersive and have distinct Wavelengths flowing at various speeds. What are Love Waves? After British mathematician, A. E. H. Love, who developed the mathematical model for this Wave type in 1911, one type of surface Wave is known as a Love Wave. WebThe relationship between Rayleigh-wave phase velocity and frequency has been widely utilized to estimate the S-wave velocities in shallow layers using the multichannel analysis of surface waves (MASW) technique. Hence, Rayleigh wave is a main focus of most near-surface seismic studies.

WebApr 11, 2024 · This Vs model is obtained by using a new method of jointly inverting P- and S-wave receiver functions, Rayleigh-wave phase-velocity data, and S-wave arrival times of teleseismic events. Webrecorded Rayleigh waves (specific type of surface wave) generated using either an active and/or passive acoustic source into a 1-D shear-wave velocity profile of the subsurface. If MASW data are acquired at multiple sites along a traverse, the output 1-D shear wave velocity profiles can be used to generate a 2-D velocity image of the subsurface.
