Simulation of Accelaration Ground Motions by Hierarchy Fault Model

Year: 1992

Type: article

Abstract: A hierarchy model is studied to simulate acceleration strong motions quantitatively both in time histories and frequency contents. The hierarchy model is formed by introducing hierarchy property into an earthquake source in addition to the heterogeneity and discontinuity in the rupture process. It is characterized by 1) average stress drop, 2) fault dimension, 3) spatial distribution of the discrete sources, 4) hierarchy order and hierarchy element length ratio. Through simulation studies of acceleration ground motions recorded during the Izu-Hanto-Toho-Oki earthquake onJuly 9, 1989, present method is found capable to explan the high frequency component up to about 4.0 Hz.
