Height and gravity measurements observed along a profile across the epicentral area before and after the January 26, 2001, Mw 7.6 Bhuj earthquake show a maximum uplift of 1.57 ¿ 0.5 m and a corresponding gravity change of -393 ¿ 18 ¿Gal. A best-fit, single-dislocation model inverted from the height-changes using non-linear optimization methods indicates that the high-slip rupture was well contained in the aftershock zone and likely did not break to depths shallower than ~10 km. Source parameters arrived in the present study agree well with those provided by seismic inversions and the distribution of aftershocks. Gravity data over the epicentral area are well modeled by the preferred model; however, a strong influence of shallow hydrological processes is inferred for three sites, two located on the Banni plains, whose mean gravity change ~280 ¿Gal suggests a total mass redistribution of as much as 2.9 Mt.
