Understanding the cause of structural damage and loss caused by surface faulting rupture requires research on the fault rupture-foundation interaction and geotechnical mitigation methods. The present study investigated the interaction of reverse-faulting surface rupture and a foundation system comprising a mat foundation and micropiles. The effects of the micropiles on the rotation of the foundation and rupture propagation was examined for different interaction mechanisms. The results suggested that the response was sensitive to the position of the foundation micropiles. It was found that the position of the foundation-micropile system relative to the rupture determined the type of interaction between the soil, rupture, micropiles, and foundation, which is significant for development of geotechnical mitigation methods.
