This patent describes a method of reducing distortion of seismic reflection event amplitudes resulting from residual normal movement. It comprises: obtaining measures of coherency; aligning corresponding reflection events in each ordered gather of seismic signals with the stacking velocities having optimum measures of coherency; obtaining measures of coherency for corresponding reflection events in the hyperbolically corrected gathers of seismic signals for a plurality of parabolic traveltime correction curves; and aligning corresponding reelection events in the hyperbolically corrected gathers of seismic signals with the parabolic traveltime correction curves having the optimum measures of coherency for reducing residual normal moveout.
