We present InSAR results of the coseismic displacement field for the January 2001 Bhuj earthquake. Using InSAR data along multiple tracks, we determine the optimal source parameters of the earthquake. The deformation pattern is first modeled assuming uniform slip on an elastic dislocation. A grid search is used to constrain the source location and finiteness assuming a strike, rake, and dip consistent with seismic studies. An inversion for the distributed slip places oblique reverse slip at depth with strike-slip motion resolved at shallower depths. The estimated size of the event is Mw 7.6. Results also suggest that the postseismic response is minimal.
