Schematic reconstruction of the seafloor scar. Based on the kinematic indicators and geometry of each MTD. a MTD 1 occurs and begins the process toward creating the seafloor scar. b MTD 2 occurs because of rapid uplift to the SW (Fig. 11a). c MTD 3 emplaces on top of MTD 1 after a ~ 0.46 Ma hiatus in landsliding. d MTD 4 occurs soon after MTD 3 and erodes the W margin and at least 1/3 of MTD 3 as well as a portion of the BSS of MTD 1. e MTD 5 is possibly a result of lateral margin failure of either MTD 3 or 4. f MTD 6 erodes a portion of MTD 4’s BSS and deposits a turbidite on its top surface. g MTD 7 erodes a portion of MTD 6’s basal shear surface and creates the W boundary of the seafloor scar. h–j Three surficial landslides finish shaping the current seafloor scar
