“…It is a resurgent nested structure formed during two major caldera collapses related to the eruptions of the Campanian Ignimbrite (CI, 39 ky BP; Fedele et al, 2004 and references therein) and the Neapolitan Yellow Tuff (NYT, 15 ky BP; Deino et al, 2004 and references therein), respectively (Orsi et al, 1996). Volcanological, geophysical and geochemical evidences (De Vita et al, 1998;De Vita et al, 1999;Dellino et al, 2001;Zimanowski et al, 2003) support the hypothesis that remnant(s) of the magma source feeding the large eruptive events of CI and NYT are involved in more recent volcanic episodes (e.g. Agnano-Monte Spina eruption, 4ky BP) and still supply heat and deep fluid release in the CFD, contributing to surface fluids emissions.…”

“…Permeability has also been measured in synthetic products from degassing experiments of volcanic material (Takeuchi et al, 2008;Bai et al, 2010Bai et al, , 2011. Mueller et al (2005Mueller et al ( , 2008) compiled a thorough dataset that includes the only permeability values measured on trachytic volcanic rocks from a past sub-Plinian event: the Agnano Monte Spina (AMS) eruption (4.1 ka, de Vita et al, 1999) from Campi Flegrei (CF), an active, hazardous caldera west of the city of Naples, Southern Italy (Fig. 1).…”

In order to understand outgassing during volcanic eruptions, we performed permeability measurements on trachy-phonolitic pyroclastic products from the Campanian Ignimbrite and Monte Nuovo, two explosive eruptions from the active Campi Flegrei caldera, Southern Italy. Viscous (Darcian) permeability spans a wide range between 1.22 × 10 −14 and 9.31 × 10 −11 m 2 . Inertial (non-Darcian) permeability follows the same trend as viscous permeability: it increases as viscous permeability increases, highlighting the strong direct correlation between these two parameters. We observe that vesicularity does not exert a first order control on permeability: the Monte Nuovo scoria clasts are the most permeable samples but not the most vesicular; pumice clasts from the Campanian Ignimbrite proximal facies, whose vesicularity is comparable with that of Monte Nuovo scoriae, are instead the least permeable. In addition, we find that sample geometry exhibits permeability anisotropy as samples oriented parallel to vesicle elongation are more permeable than those oriented perpendicular. We compare our results with permeability values of volcanic products from effusive and explosive activity, and discuss the role of melt viscosity and crystallinity on magma permeability.

“…The magmatic system of Phlegrean Fields, Naples, Italy, is an active volcanic field as demonstrated by the AD 1538 Monte Nuovo eruption, by bradyseismic crises in 1969-1972 and 1982-1984, and by widespread fumarolic and thermal springs activity (e.g., Armienti et al, 1983;Orsi et al, 1996;De Vita et al, 1999). These observations in conjunction with the extreme urbanization of the volcanic area (the area of the Phlegrean Fields caldera is inhabited by about 1.5 million people) indicate that the volcanic risk is very high.…”

We estimated the water fugacity (f H 2 O) in the trachytic magma of Phlegrean Fields using the biotite-magnetite-sanidine equilibrium. We confirm that the partly ionic model is the most appropriate to estimate annite activity (a annite ) for the experimental biotite. Crystallization experiments were carried out on a representative sample of trachytic Breccia Museo eruption, Naples, Italy. Experiments were performed in the temperature and pressure range of 725-870 °C and 50-200 MPa, and redox conditions ranging from NNO (nickel-nickel oxide) + 1 (±0.2) to FMQ (fayalite + magnetite + quartz). Most experiments were done under conditions of H 2 O saturation (P water = P total ). Few experiments were done using a mixed H 2 O-CO 2 fluid phase. The pre-eruptive fH 2 O of the Phlegrean Fields magma is estimated at 735 bars, which compares well with available melt inclusion constraints. Our results confirm that this geohygrometer can be used in any magmatic systems bearing the worked assemblage.
