Così Benedetto Croce ricorderà questo terremoto che diverrà un laboratorio per la crescita delle conoscenze sui fenomeni sismo-vulcanici. Il terremoto colpì un territorio denso di memoria storica, di paesaggi straordinari, di acque salutari, un luogo di vacanze per una clientela di élite. Il sisma accade in un momento di fervore scientifico per lo studio dei terremoti, con l’Italia capofila mondiale, e di ripensamento del ruolo del paese a livello internazionale a poco più di un decennio dall’Unità Nazionale con Roma capitale. La rinomanza dell’evento a livello europeo impegnò il Governo a un intervento massiccio per i soccorsi. Numerose personalità e famosi scienziati intervennero sulla scena del disastro; nel volume sono ricordati quelli che hanno lasciato le tracce più significative: Francesco Genala, ministro dei Lavori Pubblici; Henry James Johnston-Lavis, medico, con una grande passione e competenza per i vulcani; Luigi Palmieri, direttore dell’Osservatorio Vesuviano; Michele Stefano de Rossi, il primo a introdurre in Italia le scale di intensità per i terremoti e a realizzare una rete sismica; Giuseppe Mercalli, che propose una nuova scala delle intensità e fu direttore dell’Osservatorio Vesuviano; Giulio Grablovitz, fondatore e direttore dell’Osservatorio Geodinamico di Casamicciola.366 141 - PublicationRestrictedHeat flow and geothermal gradients of the Campania region (Southern Italy) and their relationship to volcanism and tectonicsThe heat flow and distribution of temperatures at depth in the Campania region were analysed and correlated with the volcanism and tectonics of the area. The temperature data, a part of the inventory of the AGIP, SAFEN and ENEL Companies (Inventario delle Risorse Geotermiche Nazionali), were gathered during drilling campaigns that began in 1940. The Campania region is characterised by the presence of two active and high-risk volcanic districts (the Campi Flegrei, Ischia and Vesuvius) emerging at the western boundary of the Campania Plain structural graben, and by the outcropping of the carbonate basement along the borders of the plain. The thermal anomalies have been correlated to different processes: the rising of the upper mantle (at about 20 km depth), the heat flow mass transport due to advection of hot fluids above magma reservoirs and the pure conductive heat transport of deeper crust. Furthermore, the presence of the carbonate basement has possibly buffered the deeper crustal thermal processes. The data also provided an estimation of the brittle-ductile transition zone that has been compared with the seismicity cut-off depth of the area.

; ; ; ; ; ; ; ; ; ; ; The active volcanic zone of Ischia Island and Campi Flegrei caldera (Campania) have been the site of many geothermal investigations, since the early 20th century. These areas are characterized by very high geothermal gradient and heat flow as consequence of upward migration of magmatic sources coupled with vigorous hydrothermal circulation. After the increment of installed geothermal power in Larderello (Tuscany), the extensive geothermal exploration of Campania was not followed by exploitation projects. In recent time, the attention on the possibility to exploit electric energy has been drawn by the new Italian regulation for exploitation leases. The larger geothermal potential of Campi Flegrei caldera and Ischia Island, located west to the Bay of Naples, makes these areas as possible sites of new geothermal plants installation. We present here the results of recent geothermal researches of Campi Flegrei caldera and Ischia Island, which integrate and improve the information obtained during the exploration performed by SAFEN and AGIP-ENEL companies from the earlier 1940 to 1985. These data are useful to characterize the geothermal reservoirs of this active volcanoes and also to increase the knowledge of volcanic processes and related risk.120 9 - PublicationOpen AccessField-scale permeability and temperature of volcanic crust from borehole data: Campi Flegrei, southern Italy(2018)
; ; ; ; ; ; ; ; ; ; ; ; ;We report combined measurements of petrophysical and geophysical parameters for a 501-mdeep borehole located on the eastern side of the active Campi Flegrei caldera (Southern Italy), namely (i) in situ permeability by pumping tests, (ii) laboratory-determined permeability of the drill core, and (iii) thermal gradients by distributed fiber optic and thermocouple sensors. The borehole was drilled during the Campi Flegrei Deep Drilling Project (in the framework of the International Continental Scientific Drilling Program) and gives information on the least explored caldera sector down to pre-caldera deposits. The results allow comparative assessment of permeability obtained from both borehole (at depth between 422 a 501 m) and laboratory tests (on a core sampled at the same depth) for permeability values of ~10−13 m2 (borehole test) and ~10−15 m2 (laboratory test) confirm the scale-dependency of permeability at this site. Additional geochemical and petrophysical determinations (porosity, density, chemistry, mineralogy and texture), together with gas flow measurements, corroborate the hypothesis that discrepancies in the permeability values are likely related to in-situ fracturing. The continuous distributed temperature profile points to a thermal gradient of about 200 °C km−1. Our findings (i) indicate that scale-dependency of permeability has to be carefully considered in modelling of the hydrothermal system at Campi Flegrei, and (ii) improve the understanding of caldera dynamics for monitoring and mitigation of this very high volcanic risk area.557 184 - PublicationRestricted
29 1 - PublicationRestrictedThe geothermal system of Ischia Island (southern Italy): Critical review and sustainability analysis of geothermal resource for electricity generation(2014)
; ; ; ; ; ; ; ; ; ; ; In this paper we analyze the main available data related to the geothermal system of Ischia Island, starting from the first geothermal exploration in 1939. Our aim is to define a conceptual model of the geothermal reservoir, according to geological, geochemical, geophysical and stratigraphic data. In recent times, the interest on geothermal exploitation for electricity generation in Italy is rapidly increasing and the Ischia Island is one of the main targets for future geothermal exploitation. Nowadays, one of the main economic resources of the island is the tourism, mainly driven by the famous thermal springs; so, it is crucial to study the possible interaction between geothermal exploitation and thermal spring activities. To this aim, we also analyze the possible disturbance on temperature and pressure in the shallow geothermal reservoir, due to the heat withdrawal for electric production related to small power plant size (1e5 MWe). Such analysis has been performed by using numerical simulations based on a well known thermofluid-dynamical code (TOUGH2!). Obtained results show that such geothermal exploitation generates a perturbation of temperature and pressure field which, however, is confined in a small vol- ume around the well. At shallow level (0e100 m) the exploitation does not produce any appreciable disturbance, and can be made compatible with thermal spring exploitation. Moreover, such results are crucial both for the evaluation of volcanological processes in the island and for the general assessment of geothermal resource sustainability.300 5 - PublicationOpen AccessA geophysical k-means cluster analysis of the Solfatara-Pisciarelli volcano-geothermal system, Campi Flegrei (Naples, Italy)(2018)
; ; ; ; ; ; ; ;; We present an application of the k-means cluster analysis technique to a trivariate geophysical parameter set dis- tributed over a 3 km thick and 1.2 km long section through the geothermally active Solfatara-Pisciarelli area of the Campi Flegrei caldera (Italy). The data set consists of resistivity, P-wave velocity and density parameters, ex- tracted from previously modeled univariate sections through the selected profile and mapped in a joint param- eter 3D space. Six compact and separated clusters have been identified. A subsequent linear regression statistics has allowed two distinct branches of clusters to be recognized, each represented in the joint parameter space by the equation of a plane. Each equation and its partial derivatives define the peculiar combinations among the used parameters. Once mapped back to the space domain, the final image has provided a grouping of the struc- tures in two superimposed blocks with an irregular interface located at 2 km mean depth. Based on drilling data, subsurface stratigraphy and recent seismic activity, the interface between the two blocks has been interpreted in terms of a substantial change in the rocks rheology inside the Solfatara-Pisciarelli volcano-geothermal system, namely the brittle-to-ductile transition.332 520 - PublicationRestrictedThe catastrophic 1883 earthquake at the island of Ischia (southern Italy): macroseismic data and the role of geological conditions(2010)
; ; ; ;Carlino, S.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Cubellis, E.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Marturano, A.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia; ; This article presents the results of a detailed study of the effects of the 1883 earthquake, which occurred at the island of Ischia (Gulf of Naples) and produced the total destruction of buildings in the epicentral area (Casamicciola town). Despite the moderate magnitude, this event was characterised by very high intensities (Imax = XI degree MCS) mainly due to the shallow depth of the source. The study of the earthquake shows that the intensities, which decreased rapidly with distance, were affected by source directivity, according to the causative fault geometry and tectonic structures, while local amplification of damage was observed where soft soils outcrop. The attenuation of seismic intensity with distance was evaluated using the well-known relation of intensity versus epicentral distance (Blake’s method). The diverse gradients of attenuation, observed in different directions, were ascribed to the various geological features of the shallow crust of the island. In order to evaluate the role of geology in the damage level, we computed different attenuation models for stiff and soft soils outcropping on the island. A systematic local amplification of about 1 MCS degree associated to the presence of reworked tuffs was obtained. This study also shows the influence of geological conditions on the evaluation of macroseismic data and supplies useful elements to derive a predictive map of potential site effects.380 38 - PublicationOpen AccessThe opening of Ischia Harbour (Southern italy): history, geology and natural risk.(2010-10-14)
