Introduction
[This figure completes informations given by Figure 4. It corresponds to a seismic profile
parallel to the one illustrated in Figure 4 showing broadly the same informations (type of
seismic facies) but with the localization of the DAD3 deposit]

Figure S1. Three distinct seismic facies characterize the SLD. a) Well-bedded seismic facies
surrounding the landslide deposit, b) and e) Chaotic and chaotic-to-transparent seismic facies
located at the center and the ending part of the SLD, c) Disturbed seismic facies observed
between the distal and final part. d) Zoom on the morphological front area, showing no
reflector and no sediment package allowing to distinguish the two units as previously
suggested (“D1 and D2”, Le Friant et al., 2003a) that are now interpreted as one large
submarine landslide deposit (SLD).
