Caldera of a quaternary volcano located northwest of Naples. This caldera has a diametre of 12–15 km in its main part, where at least 24 craters and small volcanic edifices are located. The erupted lavas vary in composition from K-basalts to alkali-trachyte and phonolite.


It is a very dangerous volcanic area because it includes part of the city of Naples (the districts of Bagnoli, Fuorigrotta, Pianura, Posilippo, Soccavo, and the localities of Agnano and Pisani) and the municipalities of Bacoli, Monte di Procida, Pozzuoli, and Quarto Flegreo. The area was affected in the past by numerous large explosive eruptions, the last of which occurred in 1538 at Monte Nuovo. This eruption followed a period of ground uplift, which suddenly interrupted a secular subsidence, which continued with the same rate after the eruption. A new uplift started in 1950 and reached a maximum of about 4 m in 1985 near the town of Pozzuoli. This process occurred during three major unrest periods (bradyseisms), the first in 1950-1952, the second in 1969-1972, and the third in 1982-1984. In addition, four minor uplift periods occurred in 1989, 1994, 2000 and 2006. All of the uplift periods in this area were accompanied by seismicity, and in particular, many thousands of earthquakes occurred during the two major crises in 1969-1972 and in 1982-1984.
