Theoretical and experimental results from computational physics and non‐linear rock mechanics have been merged in order to obtain a deterministic model of a stick‐slip earthquake. The model has been exercised to uncover the dependence of peak ground motion and response spectra on fault length, rupture velocity and dynamic stress drop during rupture. A particular method for generating a design spectrum has been tested against results from the model. Utilization of this deterministic technique seems especially appropriate when design information is required at sites located near the epicentre.
