The reduction of volcanic risk in the Neapolitan area

The Neapolitan area may be affected by the activity of the two volcanoes of Vesuvius and Campi Flegrei. Contingency plans have been formulated for Vesuvius and should be implemented in case of observations of anomalous precursory signals. The high population density makes the success of any large scale evacuation plans unlikely. We revise the effect of past historical eruptions which occurred in the area, and suggest possible alternative measures that can be taken by individuals also during the course of an eruption.
