Avernus was an ancient name for a volcanic crater near Cumae (Cuma), Italy, in the region of Campania west of Naples. Part of the Phlegraean Fields of volcanoes, Avernus is approximately 3.2 kilometres (2.0 mi) in circumference. Within the crater is Lake Avernus.
Cumae was the first ancient Greek colony of Magna Graecia on the mainland of Italy and was founded by settlers from Euboea in the 8th century BCE. It became a rich Roman city, the remains of which lie near the modern village of Cuma, a frazione of the comune Bacoli and Pozzuoli in the Metropolitan City of Naples, Campania, Italy.
Bradyseism is the gradual uplift or descent of part of the Earth's surface caused by the filling or emptying of an underground magma chamber or hydrothermal activity, particularly in volcanic calderas. It can persist for millennia in between eruptions and each uplift event is normally accompanied by thousands of small to moderate earthquakes. The word derives from the ancient Greek words βραδύςbradús, meaning "slow", and σεισμόςseismós meaning "movement", and was coined by Arturo Issel in 1883.
Solfatara is a shallow volcanic crater at Pozzuoli, near Naples, part of the Phlegraean Fields volcanic area. It is a dormant volcano, which still emits jets of steam with sulfurous fumes. The name comes from the Latin, Sulpha terra, "land of sulfur", or "sulfur earth". It was formed around 4000 years ago and last erupted in 1198 with what was probably a phreatic eruption – an explosive steam-driven eruption caused when groundwater interacts with magma. The crater floor was a popular tourist attraction until 2017, as it has many fumaroles and mud pools. The area is well known for its bradyseism. The vapours had been used for medical purposes since Roman times.
Pozzuoli is a city and comune (municipality) of the Metropolitan City of Naples, in the Italian region of Campania. It is the main city of the Phlegrean Peninsula.
The Phlegraean Fields is a large caldera volcano west of Naples, Italy. It is part of the Campanian volcanic arc, which includes Mount Vesuvius, about 9 km east of Naples. The Phlegraean Fields is monitored by the Vesuvius Observatory. It was declared a regional park in 2003.
Liternum was an ancient town of Campania, southern central Italy, near "Patria lake", on the low sandy coast between Cumae and the mouth of the Volturnus. It was probably once dependent on Cumae. In 194 BC it became a Roman colony. Although Livy records that the town was unsuccessful, excavation reveals a Roman town existed there until the 4th century AD.
Lake Avernus is a volcanic crater lake located in the Avernus crater in the Campania region of southern Italy, around 4 kilometres west of Pozzuoli. It is near the volcanic field known as the Phlegraean Fields and comprises part of the wider Campanian volcanic arc. The lake is roughly circular, measuring two kilometres in circumference and 60 metres (200 ft) deep.
The history of Naples is long and varied, dating to Greek settlements established in the Naples area in the 2nd millennium BC. During the end of the Greek Dark Ages a larger mainland colony – initially known as Parthenope – developed on the Pizzofalcone hill in the 8th century BC, and was refounded as Neapolis in the 6th century BC: it held an important role in Magna Graecia. The Greek culture of Naples was important to later Roman society. When the city became part of the Roman Republic in the central province of the Empire, it was a major cultural centre.
Giugliano in Campania, also known simply as Giugliano, is a city and comune (municipality) in the Metropolitan City of Naples, Campania, Italy. A suburb of Naples, as of 2017, it had some 124,000 inhabitants, making it the most populated Italian city that is not a provincial capital.
Parete is a comune (municipality) in the Province of Caserta in the Italian region Campania, located about 15 kilometres (9 mi) northwest of Naples and about 20 kilometres (12 mi) southwest of Caserta. As of 31 December 2004, it had a population of 10,597 and an area of 5.7 square kilometres (2.2 sq mi).
Line 4, mostly known as the Cumana railway is a commuter rail service in Campania, southern Italy, connecting Naples by two separate routes with Torregaveta, near Cuma in the town of Bacoli. It passes through Pozzuoli and the volcanic Campi Flegrei area.
Running beneath the Italian city of Naples and the surrounding area is an underground geothermal zone and several tunnels dug during the ages. This geothermal area is present generally from Mount Vesuvius beneath a wide area including Pompei, Herculaneum, and from the volcanic area of Campi Flegrei beneath Naples and over to Pozzuoli and the coastal Baia area. Mining and various infrastructure projects during several millennia have formed extensive caves and underground structures in the zone.
The Piscina Mirabilis is an Ancient Roman cistern on the Bacoli hill at the western end of the Gulf of Naples, southern Italy. It ranks as one of the largest ancient cisterns built by the ancient Romans, compared to the largest Roman reservoir, the Yerebatan Sarayi in Istanbul.
The Flavian Amphitheater, located in Pozzuoli, is the third-largest Roman amphitheater in Italy. Only the Roman Colosseum and the Amphitheatre of Capua are larger. It was likely built by the same architects who previously constructed the Roman Colosseum. The name "Flavian Amphitheater" is primarily associated with the Roman Colosseum.
The Villa Literno–Napoli Gianturco railway is a 16 km-long double track line which connects the line to Rome via Formia with the line to Salerno near Napoli Gianturco station through Naples and its north-western suburbs. This line is used by the metropolitan trains named as line 2.
The Macellum of Pozzuoli was the macellum or market building of the Roman colony of Puteoli, now the city of Pozzuoli in southern Italy. When first excavated in the 18th century, the discovery of a statue of Serapis led to the building being misidentified as the city's serapeum or Temple of Serapis.
Naples Metropolitan Railway service are two independent companies that operate a commuter rail system in Naples. The first one, Trenitalia, operates line 2 from Pozzuoli Solfatara to Gianturco station in East of Naples. The other one, EAV, operates the Circumvesuviana, Cumana and Circumflegrea. In Italy, Naples is the only city possessing two independent metropolitan railway service companies.

It has a characteristic heart shape. It is the southernmost of the Pontine lakes.
The Phlegraean Fields red zone is the area at greatest volcanic risk in the Phlegraean Fields, in Italy.
