Abstract

Summary

In this study, we discuss effects of an observational error of phase velocity on a shallow phase velocity profile from a numerical case. Uncertainty in S-wave velocity profile is obtained from inversion of the phase velocity using the Markov-Chain Monte Carlo. The uncertainty of S-wave velocity profile is used to estimate the variability of nonlinear soil amplification. Variability of linear amplification is also estimated as the comparison to the nonlinear one. We find that the nonlinear amplification has less variability than linear response because of decrease of shear modulus and the increase of damping in nonlinear amplification.
