Earthquake Ground Motion Modeling with Stochastic Line Sourceby Ruichong Zhang, Princeton Univ, Princeton, United States,

Abstract: Principles of geophysics and stochastics are applied to develop an earthquake model, in which the earth medium is idealized as consisting of stratified elastic layers, responding to seismic dislocations propagating along a fault line. Results are obtained for the correlation function and evolutionary spectral density at a given site, and cross-correlation function and cross-evolutionary spectral density at two sites on the ground surface.
