112 GNGTS 2015 S essione 1.2 4) the existence of faults identified by literature but not correlated with MDA anomaly; this could be due to faults putting in contact two lithologies with a similar density. Conclusion. In this paper we performed a multiparametric data analysis (by integrating seismic, tectonic and gravity data) in theAbruzzo region, central Italy, with the aim of identifying active faults and investigating the neotectonic activity of these areas. As regards gravity data, a Multiscale Derivative Analysis (MDA) of the Bouguer anomalies of the areas allowed locating several linear and closed trends and identified new faults whose presence was not previously detected. The main results of the multiparametric analysis suggest a strong correlation among faults, seismicity and the MDA lineaments from gravity data, mainly along NW-SE and NNW- SSW alignments. These faults may be considered active. Moreover, our study highlighted other possible scenarios as far as the correlation of faults, earthquakes and MDA lineaments is concerned: a) correlation between seismicity and MDA maxima that suggests the presence of buried active faults; b) correlation between faults and MDAmaxima that suggests the presence of faults that are no more active; c) correlation between faults and earthquakes that suggests the presence of faults that put in contact two lithologies with similar density. Our results yield new insight into the existence of possible buried active faults, whose knowledge is useful to the definition of the areas’ seismic risk.
