Interpreted seismic profiles and cross-section illustrating the along-strike structural variability of the necking domain of the margin. To the right, palinspastic restoration of the Red Sea at ∼14 Ma showing the main structural elements from Figure 2 and the location of the sections. Black arrows show the dip direction of the syn-rift sediments. Nubia is considered as fix in this reconstruction. Rotation pole from Delaunay et al. (2023) (Nubia-Arabia) and Reilinger and McClusky (2011) (Nubia-Danakil).
