investigating polarization of rayleigh waves in single method measurements based on the revised raydec

The knowledge of the site effects is important to the assessment of seismic hazard studies. the horizontal-to-verticalspectral ratio (h/v) method (nakamura, 1989) has been introduced as a convenient technique to estimate the fundamentalfrequency of soft deposits. the ellipticity curve analysis can be described as the elliptical motion of rayleigh waves using asingle seismic station. since love and body waves are present in the wavefield as well, the h/v curve would not completelycorrespond to the ellipticity curve. the effect of love and body waves should be minimized or removed before consideringthe h/v spectral ratio.
