In this study foundamental characteristics for earthquake fault rupture propagation in dry sand deposit ηας βεεν examined both through physical models in 1-g conditions - laboratory scale 1:20, with particular concern on dip-slip fault, and through numerical simulation of the exact same problem in prototype scale. the 1-g models where used to investigate the pattern of the rupture propagation according to fault type - normal and reverse, the displacement of the underlying fault and the reative position of the caisson foundation to the outcrop in the free field. the numerical simulation is then performed using the finite element method, after the model is adequately validated against the experimental data and concluding remarks are presented taking into account the bobliography and the comparative results from the analytical and experimental procedure.
