Description:
The Campi Flegrei caldera is a complex structure with a high population density, located west of the city of
Naples. In addition of being an active volcano it is characterized by a high seismic hazard due to both
Appennines regional earthquakes and to local earthquakes occurring during the bradyseismic crises. These
unrest phenomena are characterized by slow ground vertical movements, particularly active in the central part of
the caldera, and by a high number of low-magnitude earthquakes.
In this context, the determination of the site transfer functions of the area has a strong relevance for the Civil
Defense aimed to determine the hazard of the area. We have calculated the site transfer function with different
techniques (H/V and Generalized Inversion technique) and have collected data on the local geology with the aim
of correlating the site transfer functions with lithology and topography. This analysis has been performed on three
areas: the Astroni crater, the Camaldoli hill and the Agnano plain. A future development will be to extend this
analysis to the whole Campi Flegrei area.
