| | Abstract | | We propose an joint inversion method for estimation of a 1D S-wave velocity structure of deep sedimentary layers using S-wave parts of earthquake records, receiver function, phase velocity of Rayleigh wave and H/V spectra of Rayleigh wave for evaluating site amplification. Genetic algorithm is used in inversion to find an optional model that has the minimum misfit between observed and synthetic data. Using joint inversion method we can avoid the trade-off relation between S-wave velocity and thickness of a layer. |
