Abstract
The geological investigations of Napoli city, which represent the basic data source for geological hazard assessment, are characterized by the absence of well exposed and continuous outcrops, mainly due to the development of the urbanized area occurred in the last 50 years. In order to increase the set of available geological information, a database named GEOCITY has been realized on the base of 900 drill holes with stratigraphies reflecting the main drill-hole surveys performed during the last century. The true key moments in its construction were the homogenisation of different data and the identification of the geological formations. A detailed analysis of the drill-hole raw data allowed us to define the database entities, while the features of the deposits, the distribution of products and the reference drill holes were used to identify the geological formation. The analysis performed using the GEOCITY database made it possible to better assess volcanic hazard from Campi Flegrei and Somma-Vesuvio and the hazard related to alluvial phenomena that Napoli city is exposed to. © Springer-Verlag 2005.File | Dimensione | Formato | |
