This paper investigates the feasibility of site characterization via spectral analysis of horizontally-polarized shear (SH) waves as a means to lter the eeects of pore water for saturated soil conditions. Using a multi-layered wave propagation model to simulate the proposed testing connguration revolving around a torsionally vibrating loading plate, it is shown that the use of generalized Love ...

Problems of wave propagation in perfect magnetoelastic conductors have been studied, among others, by Knopoff [1], Dunkin and Eringen [2], Yu and Tang [3], Paria [4]. Kalishki and Rogula [5] have discussed Rayleigh waves in a semi-infinite perfect electrical conductor for a single component magnetic field. The propagation of Rayleigh-type magnetoelastic waves in a semi-infinite perfect electric...

S U M M A R Y It is well established that the Earth’s uppermost mantle is anisotropic, but there are no clear observations of anisotropy in the deeper parts of the mantle. Surface waves are well suited to observe anisotropy since they carry information about both radial and azimuthal anisotropy. Fundamental mode surface waves, for commonly used periods up to 200 s, are sensitive to structure in...

[1] Recordings in western Tibet of Rayleigh and Love waves at periods less than 70 s from aftershocks of the 2008 Sichuan earthquake cannot be matched by an isotropic velocity model beneath Tibet. These intermediate‐period Rayleigh and Love waves require marked radial anisotropy in the middle crust of Tibet, with the vertically polarized S‐ waves propagating more slowly than S‐waves with horizo...

Dispersion of Love waves is studied in a self-reinforced layer lying over an elastic non-homogeneous half space. The wave velocity equation is found to be in perfect agreement with the corresponding classical result when the anisotropic elastic parameters tend to zero. Dispersion curves for the shear wave velocity ratio and the effect of anisotropy and heterogeneity have been shown graphically....

[1] We perform a time-lapse analysis of Rayleigh and Love wave anisotropy above an underground gas storage facility in the Paris Basin. The data were acquired with a three-component seismic array deployed during several days in April and November 2010. Phase velocity and back azimuth of Rayleigh and Love waves are measured in the frequency range 0.2–1.1 Hz using a three-component beamforming al...
