The observed long period ground motions in the Kanto basin due to an earthquake which occurred near Izu Peninsula are first simulated taking into account the subsurface irregularities of the basin. The analyses using the Hyper-element method are performed for the incident wave field due to a shear dislocation source. Then some random response analyses are carried out using the same numerical model for a stochastic input motion based on an empirical source model. The ground motion characteristics in the basin for different source depths and magnitudes are discussed.
