Abstract

This paper describes digital simulation methods of strong earthquake ground motions using a seismological model. The methods described in this paper are based on the spectral representation of stochastic wave in conjunction with the seismological stochastic source model with ω-2 property and the representation theorem of elastodynamics. Numerical examples demonstrate an applicability of the proposed methods into prediction of strong earthquake ground motions in areas where strong-motion data are sparse.
