PREDICTION OF LOVE WAVE SPECTRA GENERATED DUE TO DIPPING LAYER

Abstract

Surface wave near a dipping layer is predicted by multiplying the proposed magnification factor with spectra of incident wave components. The magnification factor is expressed as the product of the influence coefficient of Love wave and the magnification factor in the surface layer. The influence coefficient of Love wave is formulated as an explicit form. It is found that the incident wave whose period is longer than Airy phase consist mostly of surface wave and predicted spectra of surface wave is close to the one of the surface wave separated from the observed earthquake motion.
