  abstract = {{T}he {A}lgerian continental margin in the western {M}editerranean formed as a back-arc basin and is today reactivated by the convergence between the {A}frican and {E}urasian plates. {I}t is one of the very rare examples of passive margins undergoing inversion expressed in a moderate seismicity of the margin and is possibly giving way for future subduction. {W}ith the objective to better know the deep structure of the margin and its associated basin, the origin of its seismicity and to study the mechanism of reactivation, five existing wide-angle seismic profiles along the margin are revisited. {T}hey were located offshore {M}ostaganem, {T}ipasa, {G}reater {K}abylia, {J}ijel and {A}nnaba. {T}hese profiles show that the basin is underlain by a 5 km thick crust of oceanic magmatic origin, possibly created at non-continuous small accretionary ridge segments. {T}he continent-ocean transition zone is narrow, except at the easternmost profile, possibly due to an opening including a shear movement. {N}o high velocity zone in the lower crust corresponding to mantle rocks has been imaged at the {A}lgerian margin. {T}he continental crust is thinned in a narrow and strongly segmented manner. {I}t is widest (70 km) in the central segment offshore {G}reater {K}abylia where there is a wider zone of distal thinned continental crust than on the other margin segments. {T}he thickest crust detected during this survey corresponds to the {A}frican continental crust and the {K}abylides blocks and is about 22-25 km thick. {T}his reduced thickness in comparison with unthinned continental crust might be due to the influence of earlier subduction at the margin, in form of erosion by the subducting slab.},
