3-D seismic coherency techniques and associated calculations of dip and azimuth of the coherent seismic reflections have been used successfully to aid in the identification and delineation of slump blocks with both high and low seismic amplitudes within a submarine canyon in the South Marsh Island area of the Gulf of Mexico. Block faces with low amplitude, but relatively high coherence, which are not evident on standard seismic time slices, can be seen on coherency time slices and dip/azimuth plots. These slump blocks produce a distinctive mottled pattern on coherency time slices and correspond to areas of high dip and varied azimuth on dip/azimuth plots. Similar coherency and dip/azimuth patterns are found elsewhere in the world, associated with slumping in areas of faulting, dewatering, and mass wasting.
