WebSurface Waves: The density of the different layers of the Earth varies. That is why there are seismic waves that can only propagate in certain directions through the Earth's crust … WebApr 11, 2024 · Both Love and Rayleigh waves are sensitive to shear-wave velocity (V S) structures (e.g., Aki & Richards, 2002), and the group/phase velocities can be used to estimate the crustal V S models. Based on the assumption that the crust is isotropic, a joint inversion of both Rayleigh- and Love-wave group/phase velocities can be applied to …

WebLove waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of 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. 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. Conventional dispersion analysis of Rayleigh waves assumes ...
