A method is disclosed for attenuating ground roll in seismic data signals. Seismic data signals are obtained from nearby seismic sensors. A difference filter is created that incorporates an estimate of ground roll differential move-out between the seismic sensors. The difference filter is then applied to the seismic data signals to produce a ground roll attenuated seismic data signal. The method can be used with one-pass and multiple-pass filter operations and can be used in connection with pairs of seismic data signals or with groups of seismic data signals from an areal pattern of nearby seismic sensors. The seismic data signals may be appropriately pre-processed and factors in addition to the ground roll differential move-out can be incorporated when creating the difference filter. The inventive method can be implemented in the time domain or in the frequency domain.
