Abstract
In this paper sedimentological, geotechnical, and age data from 7 piston cores of the continental slope and rise off the Ebro margin, North-western Mediterranean, are presented. The cores were obtained within and nearby an area that has undergone a major instability event occurred about 10 ka, known as the BIG’95. They show, at least, three distinct units, which are identified in relation to such event, namely a postlandslide, landslide and pre-landslide unit. Each one of these units shows distinct sedimentological and geotechnical characteristics interpreted in terms of depositional processes and consolidation history. The sedimentological and geotechnical data allows to infer that the BIG’95 is the result of a retrogressive slide and that the location of the channel levee complexes probably had a fundamental role in triggering the landslide, as well as controlling the location of the failure surface.
