Cavities and Hypogeal Structures of the Historical Part of the City of Catania

A factor that may contribute to significantly modify the seismic action on the surface is the presence of natural and anthropic cavities or else the presence of structures within such cavities. Italian cities do frequently have cavities and hypogeal structures that can represent a further factor of geotechnical hazard for the buildings above or for those close to such cavities. The collapse of the vaults of these cavities further represents a factor of risk for the structures inside the cavity itself. Catania has many cavities and hypogeal structures; so one of the goals of this work has been that of taking a census of them by an accurate investigation, some unknown cavities have been discovered, and together with the known cavities have been geo-settled by the geographic information system (GIS) system properly suited for Catania. In this paper a survey of the cavities under the central area of Catania city and the implementation of a GIS database of detected cavities have been implemented is presented. In the city of Catania the cavities represent a high risk for foundation stability of some buildings, so the following cavities have been studied in detail: Casa di Sant’Agata, cavity Piazza A. Di Benedetto, cavities via Lavandaoe. Pozzo Gammazita, cavity Piazza Curro, Cripta of S. Agostino Church.
