TheconvergencebetweenAfricaandEuropaplates in thecentralMediterranean is currently controlled by the NW-wards sink down of the Ionian oceanic lithosphere and its rolling-back (Faccenna et al. , 2004). This process, together with the SE spreading of the Calabrian Arc, implies the propagation of intraplate/interplate transfer fault zones. The latter commonly nucleates at the edges of the subduction system and can also propagate in the overriding plate resulting in scattered shear zone segments at the surface. Deformation at slab edges depends on the dynamics of the lower plate whose rolling-back account for detaching along ocean-continent transition and resulting in lithospheric scale tear faults (STEP, ���������� Subduction Transform Edge Propagator� ������ ��� ������� ������ ��� �������� ���� ����������� ���� ; Govers and Wortel, 2005)� �. For decades� ���� , many ����������� ���� researchers have been seeking for STEP at the western edge of the Ionian subduction system (e.g. offshore eastern Sicily), most of which have favored the Malta Escarpment (Argnani and Bonazzi, 2005; Govers and Wortel, 2005; Argnani, 2009) or others normal faults imaged by seismic profiling 128 GNGTS 2014 S essione 1.2
