Description and Validation of the Stochastic Ground Motion Model

Both the point- and finite-source stochastic ground motion models represent recent and promising developments in the quantification of strong ground motions for engineering design. The models as presented in this study combine appropriate elements of seismological source and wave propagation physics with a conventional geotechnical approach to evaluating the effects of nonlinear site response on strong ground motions. In this context, the models represent an attempt to bring together, perhaps for the first time, simultaneous consideration of earthquake source, path, and site processes.
