The tectonic domains in this area are the Calabrian accretionary wedge and the Apulian foreland. The contact between the two domains, oriented NW-SE, morphologically coincides with a sea-bottom erosional channel (Taranto canyon) characterized on both sides by mass movements induced by slope instability. Along the accretionary wedge/Apulian foreland boundary three different morphological sectors have been recognized whose main characters are represented by a southward stepped increase of erosional canyon activity resulting in a pronounced slope acclivity and a superficial sediment instability. By means of seismic data we correlate the morphology of the sea-bottom to different contractional and flexural processes of the accretionary wedge/foreland system. The interaction between the different rheological domains in the subduction/collision processes could have also induced horizontal stress represented by areas of tectonic release. In an area like this, where very few detailed surveys have been carried out, this study represents the first attempt in correlating the recent tectonic activity to the morphological features and in locating possible slope instability that has to be evaluated for the positioning of offshore infrastructures.
