Abstract
This paper describes a methodology of integrated analysis applied to the
study of geological deformation due to recent tectonics and morphogenesis on a regional
and local scale. The analysis has been carried out by integrating morphological
data, morphometrical data derived by DTMs (Digital Terrain Models) processing, with
literature geological and geomorphological data, aerial photo interpretation and field
surveys, as well as with seismological data. The study areas that have been selected
for testing our methodology are the Agri Valley (Campania-Lucania regions), hit by
the strong historical earthquake of 26th December, 1857 (Imax=XI, Me=7.0); the Tammaro
River basin (Campania-Molise regions), affected in historical time by the strong
earthquake of 5th June, 1688 (Imax=XI, Me=6.7) and in recent time by seismic sequences
of moderate energy; the Ischia Island (Thyrrenian sea - Campania region),
characterized by historical and recent volcano-tectonic activity. Finally, the consistency
and congruency of the obtained results have been verified in the light of a coherent
model of deformation source. The results obtained in this work have showed the applicability
of this methodology, so far utilized only for tectonic areas with active deformation,
also to active volcanic areas, proving the advantage of such methodological
approach for the assessment of geological-environmental hazard in an area
