This paper presents the results of experimental studies to examine propagation of fault ruptures with particular concern on dip-slip fault. Based on the results from fault box tests under 1-g and centrifuge condition, the pattern of rupture propagation through a sandy soil and the location of surface rupture were investigated. The variation of dip angle and soil density appeared as major affecting factors to form the pattern of rupture propagation. The distortion and subsidence of surface ground have been examined as well. Accordingly, it is confirmed that reproduction of fault rupture propagation in sandy soil deposit using physical model could be largely affected by its confining stresses from this research.
