Fig. 6.
a) CHIRP seismic profile across the periosteum normal fault parallel to the coast suggested to be the lineament along which the headwall of the Villafranca slide formed; b) shaded bathymetry showing the fault, the current shelf edge, the shelf edge deltas and the incisions of the slope channels.
