Abstract. The presence of three active volcanoes (Vesuvius, Campi Flegrei and Ischia
island) along the coast of Naples did not contain the huge expansion of
the urbanized zones around them. In contrast, since the Greco-Roman era, volcanoes have featured among the favourite sites for people colonizing the Campania region. The stable settlements around Vesuvius, Campi Flegrei caldera and Ischia were progressively enlarged, attaining a maximum growth rate between 1950 and 1980. Between 1982 and 1984, Neapolitans faced the
last and most dramatic volcanic crises, which occurred at Campi Flegrei
(Pozzuoli) without an eruption. Since that time, volcanologists have
focused their attention on the problem of risks associated with eruptions in the Neapolitan area, but a systematic strategy to reduce the very high
volcanic risk of this zone is still lacking. A brief history of volcanic
risk in the Neapolitan district is narrated here in an effort to provide new food for thought for the scientific community that works for the mitigation of volcanic risk in this area.
