The invention relates to a method of structural traveltime tomography which uses mismatched image information observed on common image point gathers to determine the precise location of near vertical boundaries or faults. The method can distinguish an error caused by a misplaced fault from velocity caused errors, then it reduces these errors by correcting the location of the fault. The result is a better depth image from better aligned events, and better correction to the velocities from a follow-up tomography using current velocity tomography.
