Description:
Two major deformation belts occur in the portion of the Adriatic Sea offshore the Gargano Promontory. Although
these two belts display similar characters on seismic profiles, they are different in other respects. The NE-SWtrending
Tremiti Deformation Belt, located north of the Gargano Promontory, originated during the Plio-Quaternary,
while the E-W-trending South Gargano Deformation Belt, located south of the Gargano Promontory,
formed in a time span that goes from Eocene to early Pliocene. On the ground of structural and stratigrafic
evidence these deformation belts are interpreted as originated by tectonic inversion of Mesozoic extensional
faults. This inversion tectonics, of Tertiary age, can be related to the evolution of the fold-and-thrust belts that
surround the Adriatic Sea.
A moderate seismic activity, recorded around the Tremiti Island, and historical seismological data suggest that
the whole of study area is, at present, seismically active. Therefore, this portion of the Adriatic block still
represents a preferental site of deformation.
