| Zusammenfassung |
The possible emplacement of pyroclastic fall and flow products from Campi
Flegrei and Somma-Vesuvio represents a threat for the population living in
Napoli city. For this area, the volcanic hazard was always partially
investigated to define the hazard related to the Campi Flegrei or to the
Somma-Vesuvio activity one at a time. A new volcanic hazard and risk
assessment, at the municipality scale, as a vital tool for decision-making
about territorial management and future planning, is presented here.
In order to assess the hazard related to the explosive activity of both
sources, we integrated the results of field studies and numerical
simulations, to evaluate the future possibility for Napoli to be hit by the
products of an explosive eruption. This is defined for the Somma Vesuvio
central volcano through the sum of "field frequency" based on the
thickness and distribution of past deposits (Lirer et al., 2001), and for
the Campi Flegrei volcanic field by suitably processing simulated events
based on numerical modelling (Alberico et al., 2002; Costa et al., 2009).
Aiming at volcanic risk assessment, the hazard areas were joined with the
exposure map, considered for our purposes as the economical value of
artefacts exposed to hazard. We defined four risk classes, and argued that
the medium and low-very low risk classes have the largest extent in Napoli
municipality, whereas only few zones located in the eastern part of the city
and in the westernmost coastal area show a high risk, owing to the
correspondence of high economical value and high hazard. |
