Ground differential movements due to faulting have caused damage to engineered structures and facilities in strong Earthquakes. Although surface fault rupture is not a new problem, there are only a few potential mitigation schemes in the world containing some types of provisions for reducing the risks. Fault setbacks or avoidance of construction in the proximity of seismically active faults, are usually supposed as the first priority. This paper presents the results of an investigation on the development of reasonable mitigation measures based on some 1-g physical modeling tests.
