The Phlegraean Fields (Italian: Campi Flegrei, Italian: [ˈkampi fleˈɡrɛːi]; Neapolitan: Campe Flegree) is a large caldera volcano west of Naples, Italy. [a] It is part of the Campanian volcanic arc, which includes Mount Vesuvius, about 9 km (6 miles) east of Naples. The Phlegraean Fields is monitored by the Vesuvius Observatory. [6]
The INGV recorded 1,252 earthquakes in the Campi Flegrei area in the month of April 2024, most with a magnitude less than 1.0. The last major eruption of the supervolcano was in 1538, which ...
The Campi Flegrei caldera has a diameter of about 12-15 km (7.5-9.3 miles) and last erupted in 1538. One of its biggest eruptions took place some 39,000 years ago and might have led to the ...
Although Campi Flegrei’s last major eruption was in 1538, it has shown ongoing restlessness, experiencing notable spikes of unrest in the 1950s, 1970s, and 1980s, according to LiveScience.
The Phlegraean Fields red zone (Italian: zona rossa dei Campi Flegrei) is the area at greatest volcanic risk in the Phlegraean Fields, in Italy. [1] The Phlegraean Fields is an area of volcanic calderas west of the city of Naples.
The Phlegraean Fields (Italian: Campi Flegrei "burning fields" [a]) [13] caldera is a nested structure with a diameter of around 12 km × 15 km (7.5 mi × 9.3 mi). [14] It is composed of the older Campanian Ignimbrite caldera, the younger Neapolitan Yellow Tuff caldera and widely scattered sub-aerial and submarine vents from which the most ...
The Campi Flegrei area extends west from the outskirts of Naples to the Tyrrhenian Sea. About a third is partially submerged beneath the Bay of Pozzuoli, while the remaining two-thirds are home to ...
More recently, between 1968 and 1972, the Campi Flegrei area suffered an episode of positive bradyseism and rose by 1.7 metres. Another rise of 1.8 metres occurred between 1982 and 1984. This correlated with a shallow (4 km deep) earthquake swarm during the same period, which led to the evacuation of 30,000 people due to the perceived risk of ...
