GNGTS 2015 S essione 1.2 107 on the Oristano offshore are probably associated to the Pliocene magmatic layer outcropping in the adjacent Sinis Peninsula. Aretrodeformation of a complex block geometries, recognized in a Plio-Quaternary marginal basin near the shoreline, seems to suggest a correlation between the fracture system and the coeval magmatic activity.

The aim of the study is to identify and better constrain the geometry of the seismogenic structures (������� ����������� ��� ������ ����� �������� �� ��� ������� ���� active, outcropping and buried fault systems) in the Abruzzo area (central Italy), through an ���������� �������� �� ��������������� ������� ��� ����������� ����� integrated analysis of geo-����������� � structural, seismic and gravimetric data. The studied area is one of the most active zones from a geodynamic point of view of the Italian Apennines, characterized by the occurrence of intense and widely spread seismic activity. The integrated analysis of structural, seismic and gravimetric data (Gaudiosi et al. , 2012) of the areas was carried out through the use of Geographic Information System (GIS).
