英文摘要: The Shahroud fault system is a major active structure in the Alborz range of NE Iran whose slip rate is not well constrained despite its potential high seismic hazard. In order to constrain the slip rate of the eastern Shahroud fault zone, we use space-borne synthetic aperture radar interferometry with both ascending and descending Envisat data to determine the rate of interseismic strain accumulation across the system. We invert the slip rate from surface velocity measurements using a half-space elastic dislocation model. The modeling results are consistent with a left-lateral slip rate of 4.75±0.8mm/yr on the Abr and Jajarm, strands of the Shahroud fault, with a 10±4km locking depth. This is in good agreement with the 4-6mm/yr of left-lateral displacement rate accumulated across the total Shahroud fault system obtained from GPS measurements. © 2015. American Geophysical Union.
