Rayleigh phase
WebSep 1, 2013 · 1. Introduction. Surface waves are guided and dispersive. Rayleigh (1885) waves are surface waves that travel along a free surface, such as the earth–air interface … Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. There is a phase difference between these component motions. The existence of Rayleigh waves was predicted in 1885 by Lord Rayleigh, after …

WebRayleigh wave energy is dispersive meaning that different frequencies travel with different velocities. More specifically, each frequency travels with a phase velocity that is mostly a function of the average shear-wave velocity of the subsurface from the ground surface to the base of particle motion associated with that frequency (wavelength). WebSUMMARY We obtained phase velocities of fundamental Rayleigh waves in the northwestern Pacific ocean and the northern Philippine sea from seismograms retrieved from a long-term broad-band ocean bottom seismometer (LT-OBS) array deployed in 1999‐2000 and from those recorded in Japan, Guam and Ponape islands. This array …
