STRONG GROUND MOTION PREDICTION BY USING NEW ANALYSIS METHOD NAMED PSEUDO EMPIRICAL GREENS FUNCTION PROCEDURE

In order to apply the empirical Greens function method to predict wide area strong ground motion practically, the pseudo empirical Greens function procedure is introduced and verified and an application for an earthquake in the Tokai area of Japan is also presented. For the validation of the proposed procedure, a number of transfer functions between two arbitrary recording sites estimated by the proposed procedure are compared with those of observed ground motions. The proposed procedure is shown to be able to estimate ground motions of a specific site, which has no appropriate records, better than conventional estimation methods such as the 3D-finite difference method or the stochastic simulation method. Using the proposed procedure, strong ground motions are simulated for the hypothetical Tonankai earthquake. The distribution of the simulated seismic intensity in the Nagoya area shows good agreement with that of observed building damage due to the Tonankai earthquake of 1944.
