Summary illustration comparing the models with two slope breaks and the related observations, in (a) dry conditions without sedimentation (GD12), (b) dry conditions with periodical sedimentation (GD15) and (c) aqueous conditions with periodical sedimentation (GA15). These experimental observations are compared in (d) with the natural setting observations (to the west, offshore Martinique Island). (dd’) A schematic cross-section of the submarine landslide deposit (light gray deposit) and the overlying debris avalanche deposit (dark gray) (modified from Brunet et al., 2016).
