Abstract
A technique of layer velocity estimation tbrough semblance analysis was reported in Hadleyet al. (1988) and Landa et al. (1989). lts basic premise is that a coherency measure on unstacked seismograms reaches a maximum along reflection time trajectories that correspond to the correctly estimated velocity-depth model.
