Abstract

The magnitude 6.5 Bam (Iran) earthquake occurred on a near-vertical strike-slip fault beneath the city of Bam, causing more than 26500 fatalities. In this study, we use Envisat interferograms to determine the fault geometry and slip distribution of the earthquake. Our results indicate that slip occurred on a 15 km long fault and was concentrated in the uppermost 10 km of the crust. The fault slip was primarily right-lateral strike slip with maximum of ∼3 m. Modeling of tele-seismic data indicates that a secondary thrust fault, inferred by some authors, is not required by these data, as they can be explained by slip complexities on a single fault plane. Our next step in this project will be to use both InSAR and seismic data in a joint inversion to solve for spatial and temporal complexities of fault slip in the earthquake.
