Rayleigh waves vs love waves
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, … WebSep 10, 2008 · The speed with which both types of waves circle the globe is truly mind boggling. Love waves race around the Earth at almost 10,000 miles per hour. Their relatives, the Rayleigh waves, lag behind slightly, but …

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 … 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 …
WebThe procedure has been successfully tested with real signals, specifically to extract Rayleigh and Love waves from seismograms of one aftershock of the 1999 Chi‐Chi earthquake. With the proposed procedure, we found different directions of propagation for retrograde and prograde Rayleigh waves, which might suggest that they are generated by different … WebMar 27, 2015 · Since phase velocities of Rayleigh and Love waves are different, separation of the two types of waves is in principle possible by an array observation. Their conclusion was that there was more Love wave energy than Rayleigh wave energy below 0.1 Hz but it changed above 0.1 Hz and Love wave energy became about 50% of Rayleigh wave energy.
WebLove waves shake the surface side-to-side. Rayleigh waves move the surface of the earth around in a circle, forward and down then back and up. This is the same as the motion in an ocean wave. Deeper in the ground, Rayleigh and Love waves get smaller. Underground miners seldom feel the motion of these surface 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.
