“…The Neapolitan Yellow Tuff is the most studied eruptive deposit between the Phlegrean products (Rosi and Sbrana 1987;Orsi et al 1996;Di Vito et al 1999;Pabst et al 2008). Its eruption, having a variable character from phreato-plinian to phreato-magmatic (Scarpati et al 1993;Orsi et al 1996), emitted a large amount of magmas having a composition from alkalitrachytic to latitic (Pabst et al 2008).…”

“…They correspond to a resurgent caldera (Rosi and Sbrana 1987;Di Vito et al 1999;Nunziata et al 1999;Orsi et al 2002Orsi et al , 2009D'Argenio et al 2004;Deino et al 2004;Milia and Torrente 2007;Blockley et al 2008) with a diameter of 12 km (Phlegrean caldera) resulting from the volcanotectonic collapse induced from the eruption of pyroclastic flow deposits of the Campanian Ignimbrite (35 ka). Coastal sediments ranging in age from 10 to 5.3 ka crop out 50 m above sea level in the marine terrace of La Starza (Gulf of Pozzuoli), indicating a volcano-tectonic uplift of the caldera center (Dvorak and Mastrolorenzo 1991;Morhange et al 2005).…”

A detailed reconstruction of the stratigraphic and tectonic setting of the Gulf of Pozzuoli (Naples Bay) is provided on the basis of newly acquired single channel seismic profiles coupled with already recorded marine magnetics gathering the volcanic nature of some seismic units. Inferences for the tectonic and magmatic setting of the Phlegrean Fields volcanic complex, a volcanic district surrounding the western part of the Gulf of Naples, where volcanism has been active since at least 50 ka, are also discussed. The Gulf of Pozzuoli represents the submerged border of the Phlegrean caldera, resulting from the volcano-tectonic collapse induced from the pyroclastic flow deposits of the Campanian Ignimbrite (35 ka). Several morpho-depositional units have been identified, i.e., the inner continental shelf, the central basin, the submerged volcanic banks and the outer continental shelf. The stratigraphic relationships between the Quaternary volcanic units related to the offshore caldera border and the overlying deposits of the Late Quaternary depositional sequence in the Gulf of Pozzuoli have been highlighted. Fourteen main seismic units, both volcanic and sedimentary, tectonically controlled due to contemporaneous folding and normal faulting have been revealed by geological interpretation. Volcanic dykes, characterized by acoustically transparent sub-vertical bodies, locally bounded by normal faults, testify to the magma uprising in correspondence with extensional structures. A large field of tuff cones interlayered with marine deposits off the island of Nisida, on the western rim of the gulf, is related to the emplacement of the Neapolitan Yellow Tuff deposits. A thick volcanic unit, exposed over a large area off the Capo Miseno volcanic edifice is connected with the Bacoli-Isola Pennata-Capo Miseno yellow tuffs, cropping out in the northern Phlegrean Fields.

“…However, the main tuff formation within the urban area is the TGN, well exposed along the slopes of the urban hills (Camaldoli, Posillipo, S. Martino, Poggioreale), reaching a thickness of several tens of metres up to about 100 m. The TGN consists of two members: member A, a succession of cineritic and pumiceous lapilli layers, and member B, a deposit made of cineritic layers with dispersed rounded pumices (Morra et al, 2010). The volcaniclastic sequence is closed by loose, unconsolidated pyroclastic deposits referable to 75 volcanic units (Di Vito et al, 1999): their ages range between 15 ka and the 1538 AD eruption of Mt. Nuovo.…”

Abstract.Results deriving from a research focused on the interplay between landslides and urban development are presented here, with reference to two densely populated settings located in the Campania region, Italy: the city of Naples and the island of Ischia. Both areas suffer adverse consequences from various types of landslides since at least 2000 yr. Our study evidences that, despite the long history of slope instabilities, the urban evolution, often illegal, disregarded the high landslide propensity of the hillsides; thus, unsafe lands have been occupied, even in recent years, when proper and strict rules have been enacted to downgrade the landslide risk. It is finally argued that future guidelines should not be entirely based upon physical countermeasures against mass movements. On the contrary, national and local authorities should enforce the territorial control, obliging citizens to respect the existing regulations and emphasizing the role of alternative, non-structural solutions.

“…After NYT eruption intracaldera volcanism [5] lasted until the most recent eruption of Monte Nuovo (1,538 AD). The Campi Flegrei Caldera is interested by historical episode of slow ground deformations (called bradyseism) in its central part, nearby the town of Pozzuoli, due mainly to variations of the fluid pressure in the geothermal system [6].…”

“…In the last six years, the same area is characterized by an uplift of about 2 cm/yr. Solfatara tuff-cone took place with a low-magnitude eruption occurred between 4.1 and 3.8 kyr [5] ad it is made mainly of pyroclastic current deposits, phreatomagmatic coarse breccias and subordinately fallout pumice deposits. The morphology of Solfatara crater is controlled by NW-SE and SW-NE trending faults whose junction is the place of the most impressive example of hydrothermal activity at Campi Flegrei.…”

Solfatara and Pisciarelli areas are the most impressive example of hydrothermal activity at Campi Flegrei caldera (Southern Italy). In these areas INGV-Osservatorio Vesuviano has been handling since 2004 a surveillance network for continuous, long-term volcanological monitoring of fumaroles fields by using thermal IR acquisition stations. In this paper different methodologies of analysis applied to time series of IR scenes are introduced and discussed. In spite of substantially different approaches to data analysis, the results of these methodologies agree with ground deformation data of the same area and likely are a useful tool for volcano monitoring and long-term risk definition.
