"WebJan 3, 2024 · Surface-wave analysis has been widely used for near-surface geophysical and geotechnical studies by using the dispersive characteristic of surface waves (Rayleigh or Love waves) to determine subsurface model parameters. Unlike Rayleigh waves, the dispersive nature of Love waves is independent of P-wave velocity in 1D models, which … " - Rayleigh waves vs love waves

Rayleigh waves vs love waves

WebThe waves that arrive between the P and S waves are waves that started out as P waves, but bounced off of features in the Earth or at the surface and arrived at the seismic station a little later. The surface waves (Love and Rayleigh waves) are the other, often larger, waves marked on the seismogram. WebThere are several types of surface wave, but the two most common varieties are Rayleigh waves and Love waves. Rayleigh waves. Rayleigh waves, also known as ground roll, spread through the ground as ripples, similar to …

WebApr 11, 2024 · Joint inversion of the S1222a Rayleigh- and Love-wave group velocities provides 1D isotropic velocity models of the regional Martian crust. These models indicate a high-velocity layer at ∼7 km depth which could be due to the regional basaltic activity or the regional stress field. Web2 days ago · Introduction. Surface waves (e.g., Rayleigh and Love waves) exhibit dispersive characteristic in horizontally stratified media. Group-velocity and phase-velocity dispersion curves of surface waves are highly sensitive to shear (S) wave velocity property but less sensitive to other physical properties, including density and compressional wave velocity …

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 seismology longitudinal and shear waves are known as P-waves and S-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.
