Campi Flegrei, also known as the Phlegraean Fields, is a large 13 kilometres (8.1 mi) wide caldera situated to the west of Naples, Italy. It was declared a regional park in 2003. Lying mostly underwater, the area comprises 24 craters and volcanic edifices. Hydrothermal activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are also effusive gaseous manifestations in the Solfatara crater, which is known as the mythological home of the Roman god of fire, Vulcan. The area also features bradyseismic phenomena, which are most evident at the temple of Serapis in Pozzuoli. Volcanic deposit indicating possible eruption dated Ar at 315, 205, 157 and 18.0 kya. The caldera, which now is essentially at ground level, is accessible on foot. It contains a large number of fumaroles, from which steam can be seen issuing, and over 150 pools of boiling mud at last count. Several subsidiary cones and tuff craters lie within the caldera. One of these craters is filled by Lake Avernus. In 1538, an eight-day eruption in the area deposited enough material to create a new hill, Monte Nuovo. It has risen about 2 metres (6.6 ft) from ground level since 1970. It is a volcano capable of producing VEI 7 eruptions, as large as that of Tambora in 1815. At present, the Campi Flegrei area comprises the Naples districts of Agnano and Fuorigrotta, the area of Pozzuoli, Bacoli, Mount Procida, Quarto, the Phlegrean Islands (Ischia, Procida and Vivara). Recent inflation of the caldera centre in the vicinity of Pozzuoli may presage an eruptive event within decades. |
