Rayleigh velocity
WebThe shear‐wave (S-wave) velocity of near‐surface materials (soil, rocks, pavement) and its effect on seismic‐wave propagation are of fundamental interest in many groundwater, engineering, and environmental studies. Rayleigh‐wave phase velocity of a layered‐earth model is a function of frequency and four groups of earth properties: P-wave velocity, S … WebJan 1, 2006 · In a celebrated paper, Rayleigh first demonstrated the existence of these waves (see ref. [1]), which now bear his name (Rayleigh waves). He further showed that the effect of these non-dispersive surface waves decreases rapidly with depth, and their velocity of propagation is smaller than that of the body waves, and also that it is a root of the …

WebJan 11, 2016 · 1 Introduction. Although Rayleigh wave dispersion data have been extensively used to study the lithosphere and upper mantle velocity structure [e.g., Shapiro et al., 2005; Yang et al., 2007], it is widely accepted that the relative long-period Rayleigh waves (>8 s) extracted from either earthquakes or ambient noise have very limited resolution on … WebThe phase velocity of Rayleigh waves equals υ R ≈ 0.9υ T, where υ T is the phase velocity of the share mode. The velocity vector of these waves is parallel to the surface, whereas oscillating particles can have both transverse (perpendicular to surface) and longitudinal components of the displacement vector.
