Formerly: Colorado School of Mines Golden CO80401 USA 2 Norwegian University of Science and Technology N-7491 Trondheim Norway 3 Center for Wave Phenomena Colorado School of Mines Golden CO80401 USA Abstract Wepresent amethod for migration velocity analysis in complex media that does not depend on picking traveltime misfits or residual moveout in common image gathers (CIGs). Our method constructs CIGs in the scattering-angle/azimuth domain where we apply semblance or differential semblance to measure the coherency of events. Since amplitude
