Abstract
The major Quaternary faults in Alborz – Central Iran border zone can be classified based on their strikes into three sets: northeast, northwest and east – west.  In this paper, we have used a model to evaluate their movement potential that presented by Lee et al. (1997). Their theoretical model is based on the relationship between fault geometrical characteristics and regional tectonic stress field. The results show that the north Semnan and the north Sorkheh fault zones are of the highest movement potential in the area, despite the lack of their seismic records.
