Abstract: Various implementations directed to seismic data processing using joint tomography are provided. In one implementation, a method may include receiving seismic data corresponding to a region of interest. The method may also include generating one or more first gathers and one or more second gathers based on the seismic data. The method may further include determining a relative shift in depth between at least a first event in the one or more first gathers and at least a second event in the one or more second gathers. The method may additionally include performing a joint tomography based at least in part on the first event, the second event, and the determined relative shift.
