Following eruption of the NYT a large number of eruptions have taken place from widely scattered subaerial and submarine vents. About 500,000 people live inside the Campi Flegrei caldera depression. Correlation scheme between the stratigraphic framework in the study area (central sector of continental Campi Flegrei caldera) and offshore (Gulf of Pozzuoli). In order to assess the hazards related with tephra loading, we have considered three different eruption scenarios representative of past activity: a high-magnitude event similar to the 4.1 ka Agnano-Monte Spina eruption, a medium-magnitude event, similar to the ∼3.8 ka . Understanding how magma is transferred from a magma reservoir to the surface before eruptions is a major challenge. View of the eastern part of the populated Campi Flegrei caldera from the Camadoli Hill. Res. On the mainland west of Naples lies the Campi Flegrei, meaning 'burning fields'. Łączna liczba mieszkańców kaldery to ok. 360 tys. The Campi Flegrei caldera is a part of the 'Roman Volcanic Province' of central Italy. It is a low-lying volcano completely surrounded by populated areas in the town of Pozzuoli. This event has been the only eruption of Campi Flegrei in almost 4,000 years. (a) Location and reconstructed boundary of the Campi Flegrei caldera [after Rosi and Sbrana, 1987; Orsi et al., 1996]; (b) map showing type and location of the vents, and extension and elevation (black dots are from new and reinterpreted borehole data) of the marine sediments between 4.1 and 3.8 ka.Major inland structural lineaments of the central-eastern and western sector of the CF caldera .

More than 300,000 people live within this active caldera that has experienced more than 60 eruptions in the last 15,000 years. The CF is characterized by an outer caldera rim, about 12 km in diameter The volcano is the source of the Masseria del Monte Tuff eruption 29,000 years ago. Abstract. Contrary to what the name suggests, this is a region of lovely green hills with vineyards and lemon and orange orchards, so different from the barren, brown Vesuvius. We investigated the major episodes of dome growth in the Campi Flegrei caldera occurred during the last period of large eruptive activity (Epoch 3, between 5.5 and 3.5 ka), and in the historical time. Houses are built right to the crater rim. The Campi Flegrei caldera, hereafter CF, near Naples (Italy), is a complex volcanic sys-tem with several, mostly monogenic, explosive vents (fig. (2014). Mysterious eruption came from Campi Flegrei caldera. (Getty) Scientists have discovered a "hot zone" feeding a supervolcano near Naples in southern . Supervolcanoes are usually characterized by a large caldera, or depression, that formed from past explosive eruptions. Quasi un milione di persone vive a Napoli e oltre 3 milioni .

The first doming event occurred at the start of Epoch 3 where the caldera floor raised for at least 100 m. Following the Plinian eruption of Agnano-Monte Spina (AMS, 4.55 ka), a new uplift phase . Here we exploit the historical, archaeological and geological record of Campi Flegrei caldera to estimate the surface deformation preceding the Monte Nuovo eruption and investigate the shallow magma transfer. This is a seven-year study (1/7/2011-31/12/2017) of radon monitoring at two sites of Campi Flegrei caldera (Neaples, Southern Italy) that in the last 70 years experienced repeated phases of volcanic unrest. Calderas are collapse structures related to the emptying of magmatic reservoirs, often associated with large eruptions from long-lived magmatic systems. : Aseismic strain episodes at Campi Flegrei Caldera, Italy 121 improved in the last forty years by distance change measure-ments (originally EDM surveys and since 1995 GPS), level-ling (referenced to a benchmark located in Naples), gravity and broad band seismic data acquisition. the aim of obtaining a morphometric representation of the Campi Flegrei caldera in m (TRI and ER)or m21 asmeasurementunits. A classic example is the Campi Flegrei caldera in southern Italy, where three episodes of major uplift since 1950 have raised its central district by about 3 m without an eruption. Sie gelten als Region mit dem höchsten Vulkanrisiko der Welt - die Phlegräischen Felder bei Neapel. It was preceded by a few decades of sporadic earthquakes swarms and noticeable uplift of the shoreline and was followed by 430 years of quiescence. The X‐X′ cross section was modified after Sacchi et al. Campi Flegrei caldera vulcanica della Solfatara a Pozzuoli. The Campi Flegrei caldera cluster is the largest volcanic feature along the Bay of Naples, which is also home to the more famous Vesuvius.The Campi Flegrei, or "Fiery Fields," is built from a series of overlapping volcanic features—calderas, domes, and cinder cones—that are historically active. A view across the Campi Flegrei caldera. The area of the caldera consists of 24 craters and volcanic edifices; most of them lie under water. The Campi Flegrei caldera (CFc) directly threatens a population of several hundred thousands who lives inside the caldera, and the city of Naples itself (∼ 1 million inhabitants), just outside the caldera.The latest eruption occurred in 1538, ∼ 4,000 years after the previous one that closed a period of intense eruptive activity (Orsi et al.1996). Campi Flegrei is a 13-km-wide caldera that encompasses part of Naples and extends to the south beneath the Gulf of Pozzuoli. Eruption forecasting and hazard assessments at the restless Campi Flegrei caldera, within the Neapolitan volcanic area, have been performed using stratigraphical, volcanological, structural and petrological data.On the basis of the reconstructed variation of eruption magnitude through time, we hypothesize that the most probable maximum expected event is a medium-magnitude explosive eruption . It is a low-lying volcano completely surrounded by populated areas in the town of Pozzuoli.
