Campi Flegrei, Southern Italy
Location and setting: Campanian Region, Southern Italy, collapse caldera.
Background information: 60 years of unrest characterized by ground movements (bradyseismic activity), seismic swarms, gravity changes, and geochemical variations at fumaroles. Geophysical and geochemical signals display high degree of correlation. The unrest crisis in 1982-84 produced about 1.5 m of uplift in the town of Pozzuoli, and caused evacuation of more than 40,000 inhabitants. Caldera is located in a densely populated area including part of the city of Naples. About 500,000 people live inside the Campi Flegrei caldera depression.
Relevance to project: Type volcano regarding the behaviour of unrest calderas, and the management of unrest crises in densely populated areas and megacities. High level of knowledge (5 dedicated national projects during last 10 years, about 200 scientific publications in ISI journals during last 20 years), longlasting unrest, and previous experience in crisis management, ensure ideal test case for application of new methods and paradigms under development in the project.
Monitoring data available to consortium: seismic (short and broadband), geodetic (including levelling, GPS, InSAR, gravity, EDM, tilt, volumetric strain), and gas data up to 30 years back.
