Description:
Campi Flegrei caldera is located just west of the city of
Naples, within the central-southern sector of a large graben called
Campania Plain. It is an active volcanic area marked by a quasicircular
caldera depression, probably formed by a huge
ignimbritic eruption occurred about 39000 years ago. This
caldera was generated by collapses produced by strong explosive
eruptions. The only eruption in historical times occurred in 1538building a spatter cone called Mt. Nuovo. Campi Flegrei area
periodically experiences significant deformation episodes, with
uplift phenomena reaching more than 3.5 m in 15 years (from
1970 to 1984), which caused during 1983-84 the temporary
evacuation of about 40000 people from Pozzuoli town.
The structural complexity of the Campi Flegrei area, together
with the evidence of a strong interaction between magmatic
chamber and shallow geothermal system, calls for a detailed
characterization of the substructure and of the magma-water
interaction processes.
The Campi Flegrei caldera is characterized by high volcanic
risk due to the explosivity of the eruptions and to the intense
urbanization of the surrounding area, and has been the site of
significant unrest for the past 2000 years (DE NATALE et alii,
2006). The caldera floor was raised to about 1.7 meters between
1968 and 1972; then a subsidence phase of about 0.2 m occurred
between 1972 and 1975 followed by a stable period until 1981.
Between 1982 and 1985 new uplift occurred and the caldera rose
about 1.8 m, without eruptive phenomena...
