Campi Flegrei, also known as the Phlegraean Fields, is a large 13 km (8 mi) wide caldera situated to the west of Naples, Italy. In topography a summit is a point on a surface which is higher in Elevation than all points immediately adjacent to Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest A geographic coordinate system enables every location on the Earth to be specified in three coordinates using mainly a spherical coordinate system. Mountains can be characterized in several ways Some mountains are Volcanoes and can be characterized by the type of lava and eruptive history A caldera is a cauldron-like volcanic feature formed by the collapse of land following a volcanic eruption A volcanic arc is a chain of volcanic islands or Mountains formed by Plate tectonics as an oceanic Tectonic plate subducts under A volcanic belt is a large volcanically active region Other terms are used for smaller areas of activity such as volcanic fields Volcanic belts are found above zones The Campanian volcanic arc is a Volcanic arc that consists of a number of active dormant and extinct volcanoes in the Campania province of Italy. The geologic time scale is a chronologic schema (or idealized Model) relating Stratigraphy to time that is used by Geologists and other Plate tectonics and hotspots Divergent plate boundaries At the A caldera is a cauldron-like volcanic feature formed by the collapse of land following a volcanic eruption Naples ( Napoli, Neapolitan: Nàpule) is a historic City in southern Italy, the Capital of the Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest Today most of the area lies underwater, but it includes the town of Pozzuoli and the Solfatara crater, mythological home of the Roman god of fire, Vulcan. Pozzuoli is a city of the Province of Naples, in the Italian region of Campania. Solfatara is a shallow Volcanic crater at Pozzuoli, near Naples, and is part of the Campi Flegrei volcanic area In ancient Roman religion and Hellenic neopaganism, Vulcan is the god of beneficial and hindering fire including the fire of Volcanoes He is also It is thought that the caldera was created in two major events. The first occurred about 40,000 years ago, erupting about 200 km³ of magma (500 km³ bulk volume) to produce the Campanian Ignimbrite. Campania is a region of Southern Italy in Europe. The region has a population of around 5 Ignimbrite is a Volcanic Pyroclastic rock often of Dacitic or Rhyolitic composition Approximately 12,000 years ago another major eruption occurred, forming a smaller caldera inside the main one, centered on the town of Pozzuoli. Pozzuoli is a city of the Province of Naples, in the Italian region of Campania. This event produced the Neopolitan Yellow Tuff, referring to the characteristic yellow rocks there.
The area was known to the Greeks, who had a colony nearby at Cumae. There is also a small modern Greek Euboean city called Κυμη, near the ruins of the ancient Cuma
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 a number of pools of boiling mud. Several subsidiary cones and tuff craters lie within the caldera. One of these craters is filled by Lago d'Averno. Lake Avernus (or Lago d'Averno in Italian) is a volcanic Crater lake located in the Campania region of southern Italy, In 1538, an eight-day eruption in the area deposited enough material to create a new hill, Monte Nuovo ("new mountain"). Monte Nuovo is a Cinder cone Volcano within the Campi Flegrei Caldera.
Patrick Moore used to cite Campi Flegrei as an example of why the impact craters on the moon must be of volcanic origin, which was thought to be the case until the 1960s. Sir Alfred Patrick Caldwell-Moore, CBE, HonFRS, FRAS (born 4 March 1923 in Pinner) known as Patrick Moore, is In the broadest sense the term impact crater can be applied to any depression natural or manmade resulting from the high velocity impact of a projectile with larger body
