Phlegraean Fields
The Phlegraean Fields (, ; ) is a large volcano, volcanic caldera west of Naples, Italy. The Neapolitan Yellow Tuff eruption (about 12ka BP) produced just 50 cubic kilometers. It is, however, one of relatively few volcanoes large enough to form a caldera. It is part of the Campanian volcanic arc, which includes Mount Vesuvius, about east of Naples. The Phlegraean Fields is monitored by the Vesuvius Observatory. It was declared a regional parks of Italy, regional park in 2003. The Phlegraean Fields' largest known eruptions have an estimated volcanic explosivity index (VEI) of 7. It is often called a supervolcano in popular media, although the accepted definition for that term is a volcano that has had an eruption with a VEI of 8, the highest level. The area of the caldera consists of 24 craters and volcanic edifices. Most of them lie under the Gulf of Naples. There are effusive gaseous manifestations in the Solfatara (volcano), Solfatara crater, which was Religion in ancient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermitage Of Camaldoli
The Hermitage of Camaldoli, in Italian Complesso dell'Eremo dei Camaldoli, is a hermitage in Naples, Campania, Italy — also known in Italian as ''Eremo Santissimo Salvatore Camaldoli.'' Originally intended as an actual hermitage, a place for religious seclusion for male ascetics, the complex has served Brigidine nuns since 1998. The complex is located at Via dell'Eremo 87, at an elevation of 458 meters (1502'), the highest point in Naples. History Founded at the request of Giovanni D'Avalos, son of Alfonso d'Avalos, Alfonso d'Avalos, Marquise del Vasto, the hermitage was constructed in 1585 by the Camaldolese congregation of Monte Corona on the ruins of an ancient chapel, founded by San Gaudioso in 439. On November 23, 1662, Pope Alexander VII elevated the Hermitage to a Novitiate. In May 1771, Pope Clement XIV combined it with three other convents. During its life, the monastery was suppressed twice; first during the Napoleonic period in 1807. With the beginning of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Explosivity Index
The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The scale is open-ended with the largest eruptions in history given a magnitude of 8. A value of 0 is given for non-explosive eruptions, defined as less than of tephra ejected; and 8 representing a supervolcanic eruption that can eject (240 cubic miles) of tephra and have a cloud column height of over . The scale is logarithmic, with each interval on the scale representing a tenfold increase in observed ejecta criteria, with the exception of between VEI-0, VEI-1 and VEI-2. Classification With indices running from 0 to 8, the VEI associated with an eruption is dependent on how much volcanic materia ...

Gastrochaenolites
''Gastrochaenolites'' is a trace fossil formed as a clavate (club-shaped) boring in a hard substrate such as a shell, rock or carbonate hardground. The aperture of the boring is narrower than the main chamber and may be circular, oval, or dumb-bell shaped. ''Gastrochaenolites'' is most commonly attributed to bioeroding bivalves such as '' Lithophaga'' and ''Gastrochaena''. The fossil ranges from the Ordovician The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era, and the second of twelve periods of the Phanerozoic Eon (geology), Eon.

Serapis
Serapis or Sarapis is a Egyptian Greeks, Graeco-Egyptian god. A Religious syncretism, syncretic deity derived from the worship of the Egyptian Osiris and Apis (deity), Apis, Serapis was extensively popularized in the third century BC on the orders of Greek Pharaoh Ptolemy I Soter, as a means to unify the Greek and Egyptian subjects of the Ptolemaic Kingdom. The of Serapis was spread as a matter of deliberate policy by subsequent Ptolemaic kings. Serapis continued to increase in popularity during the Roman Empire, often replacing Osiris as the consort of Isis in temples outside Egypt. Alongside his Egyptian roots he gained attributes from other deities, such as chthonic powers linked to the Greek Hades and Demeter, and benevolence derived from associations with Dionysus. Etymology Originally known as Demotic (Egyptian), Demotic , ('Osiris-Apis (deity), Apis'), the name of the deity is derived from the syncretic worship of Osiris and the bull Apis as a single deity under the Egy ...

Macellum Of Pozzuoli
The Macellum of Pozzuoli () was the macellum or market building of the Colonia (Roman), 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. A band of borings or ''Gastrochaenolites'' left by marine ''Lithophaga'' bivalve molluscs on three standing marble columns indicated that these columns had remained upright over centuries while the site sank below sea level, then re-emerged. This puzzling feature was the subject of debate in history of geology, early geology, and eventually led to the identification of bradyseism in the area, showing that the Earth's crust could be subject to gradual movement without destructive earthquakes. Roman origins The city of Dicaearchia, founded by Greek refugees escaping dictatorship on Samos, was integrated into the Roman Empire as the city of Puteoli in 194 BC. The mac ...

Bradyseism
Bradyseism is the gradual uplift (positive bradyseism) or descent (negative bradyseism) 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 βραδύς ''bradús'', meaning "slow", and σεισμός ''seismós'' meaning "movement", and was coined by Arturo Issel in 1883. Phlegraean Fields The area of Phlegraean Fields (Campi Flegrei), near Naples, is a collapsed caldera, namely a volcanic area formed by several volcanic edifices, which includes the Solfatara volcano, well known for its fumaroles. The Campi Flegrei area is especially noted for bradyseismic uplift and subsidence. The inflation and deflation of this caldera is especially well documented due to its seaside location and a ...

Vulcan (mythology)
Vulcan (, in archaically retained spelling also ''Volcanus'', both pronounced ) is the god of fire including the fire of volcanoes, deserts, metalworking and the forge in ancient Roman religion and Roman mythology, myth. He is often depicted with a blacksmith's hammer. The Vulcanalia was the annual Roman festival, festival held August 23 in his honor. His interpretatio graeca, Greek counterpart is Hephaestus, the god of fire and smithery. In Etruscan religion, he is identified with Sethlans (mythology), Sethlans.

Religion In Ancient Rome
Religion in ancient Rome consisted of varying imperial and provincial religious practices, which were followed both by the Roman people, people of Rome as well as those who were brought under its rule.

Their Polytheism, polytheistic religion is known for having honoured List of Roman deities, many deities. The presence of Magna Graecia, Greeks on the Italian peninsula from the beginning of the historical period influenced Culture of ancient Rome, Roman culture, introducing some religious practices that became fundamental, such as the of Apollo.

Solfatara (volcano)
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 Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma (sometimes colloquially but incorrectly referred to as ''lava'') is found beneath the surface of the Earth, and evidence of magmatism has also ....
