Modeling of Seismic Waves Using Chirp Signals and Simulations

Abstract

A method of modeling the seismic waves is proposed using the chirplet-based approximation incorporating with the spectral representation of the real earthquake-induced ground motion. Detail algorithm for the chirplet-based approximation is presented and three typical earthquake data are modeled. Furthermore, the seismic waves are generated artificially using the spectral representation with evolutionary power spectrum due to Priestley.
