    Beschreibung: The Marsili Seamount (MS) is an about 3200 m high volcanic complex measuring 70 × 30 km with the top at ~500 m b.s.l. MS is interpreted as the ridge of the 2 Ma old Marsili back-arc basin belonging to the Calabrian Arc–Ionian Sea subduction system(Southern Tyrrhenian Sea, Italy). Previous studies indicate that theMS activity developed between 1 and 0.1 Ma through effusions of lava flows. Here, new stratigraphic, textural, geochemical, and 14C geochronological data from a 95 cm long gravity core (COR02) recovered at 839 m bsl in theMS central sector are presented. COR02 contains mud and two tephras consisting of 98 to 100 area% of volcanic ash. The thickness of the upper tephra (TEPH01) is 15 cm, and that of the lower tephra (TEPH02) is 60 cm. The tephras have poor to moderate sorting, loose to partly welded levels, and erosive contacts, which imply a short distance source of the pyroclastics. 14C dating on fossils above and below TEPH01 gives an age of 3 ka BP. Calculations of the sedimentation rates from the mud sediments above and between the tephras suggest that a formation of TEPH02 at 5 ka BP MS ashes has a high-K calcalkaline affinity with 53 wt.% b SiO2 b 68 wt.%, and their composition overlaps that of the MS lava flows. The trace element pattern is consistent with fractional crystallization from a common, OIB-like basalt. The source area of ashes is the central sector of MS and not a subaerial volcano of the Campanian and/or Aeolian Quaternary volcanic districts. Submarine, explosive eruptions occurred atMS in historical times: this is the first evidence of explosive volcanic activity at a significant (500–800 m bsl) water depth in the Mediterranean Sea.MS is still active, the monitoring and an evaluation of the different types of hazards are highly recommended.

    Beschreibung: We present a method to minimize the error of temperature estimate when multiple discrete populations of glass and clinopyroxene occur in a single heterogeneous eruptive unit. As test data we have used ~1100 clinopyroxene–melt pairs from isothermal and thermal gradient experiments. These latter are characterized by the crystallization of multiple modes of clinopyroxene as frequently documented for chemically and thermally zoned magma chambers. Equilibrium clinopyroxene–melt pairs are identified through the difference between predicted and measured components in clinopyroxene. The use of these equilibrium compositions as input data for one of the most recent clinopyroxene-based thermometers demonstrates that the error of temperature estimate is minimized and approaches to the calibration error of the thermometric model. To emphasize the paramount importance of this method for predicting the crystallization temperature of heterogeneousmagmas, we have tested for equilibrium~480 and ~150 clinopyroxene–melt pairs fromthe explosive eruptions of the Sabatini Volcanic District (Latium Region, Central Italy) and the Campi Flegrei Volcanic Field (Campanian Region, Southern Italy), respectively. These eruptions were fed by zoned magma chambers, as indicated by the occurrence ofmultiple modes of clinopyroxene in the eruptive units. Results fromcalculations demonstrate that clinopyroxene–melt pairs in equilibrium at the time of eruption are effectively captured by our method and, consequently, the error of temperature estimate is significantly reduced.

    Beschreibung: The time for a first book on Geoethics has come. The faster, greedier pace of society and globalization demands it. The comfortable life of scholars in the ivory tower is coming to a rude awakening. People demand understandable information on geohazards, judges condemn scientist and engineers for lack of communication, indigenous people rise in anger accusing experts of misleading them, attempts to avoid transparency in developments still exist, the helplessness of technology to deal with nuclear waste becomes more evident everyday and nature exposes shortcuts in constructing critical facilities with her own awesome force.....

    Beschreibung: Volcanic and geothermal aspects both exist in many geologically young areas. In these areas the heat transfer process is of fundamental importance, so that the thermal and fluid-dynamic processes characterizing a viscous fluid in a porous medium are very important to understand the complex dynamics of the these areas. The Campi Flegrei caldera, located west of the city of Naples, within the central-southern sector of the large graben of Campanian plain, is a region where both volcanic and geothermal phenomena are present. The upper part of the geothermal system can be considered roughly as a succession of volcanic porous material (tuff) saturated by a mixture formed mainly by water and carbon dioxide. We have implemented a finite elements approach in transient conditions to simulate water flow in a 2-D porous medium to model the changes of temperature in the geothermal system due to magmatic fluid inflow, accounting for a transient phase, not considered in the analytical solutions and fluid compressibility. The thermal model is described by means of conductive/convective equations, in which we propose a thermal source represented by a parabolic shape function to better simulate an increase of temperature in the central part (magma chamber) of a box, simulating the Campi Flegrei caldera and using more recent evaluations, from literature, for the medium’s parameters (specific heat capacity, density, thermal conductivity, permeability). A best-fit velocity for the permeant is evaluated by comparing the simulated temperatures with those measured in wells drilled by Agip (Italian Oil Agency) in the 1980s in the framework of geothermal exploration. A few tens of days are enough to reach the thermal steady state, showing the quick response of the system to heat injection. The increase in the pressure due to the heat transport is then used to compute ground deformation, in particular the vertical displacements characteristics of the Campi Flegrei caldera behaviour. The vertical displacements range from 1 cm to 10 cm in accordance with the mini uplift, characterizing the recent behaviour of the caldera. The time needed to move fluid particles from the bottom to the upper layer (years) is compatible with the timing of the mini uplift.

    Beschreibung: Il vulcano Somma-Vesuvio è una delle aree mineralogicamente più ricche al mondo e sicuramente la prima in Italia. Fino ad oggi vi sono state rinvenute 266 diverse specie mineralogiche (a cui aggiungere 20 dubbie per mancanza di dati specifici); di queste ben 64 sono da considerarsi località tipo, cioè ritrovate per la prima volta in questo luogo. Dieci di esse sono state ritrovate esclusivamente su questo vulcano. I primi studi sistematici comparvero nel Settecento (Hamilton, 1776-79), per proseguire nell’Ottocento con Teodoro Monticelli, Nicola Covelli (1825) e Arcangelo Scacchi (1887), e, nel Novecento, con Ferruccio Zambonini (1935) e Antonio Parascandola. Il catalogo più recente è del 2004 (Russo & Punzo, 2004). Dal 1995, anno di istituzione del Parco Nazionale del Vesuvio, a scopo di tutela, vige il divieto assoluto di “prelievo di materiali di rilevante interesse geologico e paleontologico”.

    Beschreibung: This chapter outlines a framework of the issues addressed by geoethics. Starting from an etymological analysis of the word “geoethics,” we identify the cultural basis on which to expand the debate on geoethics, while also proposing for consideration by the scientific community some questions that may guide the development of future research and practice in geosciences. We attempt to define some fundamental points that, in our opinion, will strengthen geoethics and help its development. The goal of geoethics is to suggest practical solutions and provide useful techniques, and also to promote cultural renewal in how humans perceive and relate to the planet, through greater attention to the protection of life and the richness of the Earth, in all its forms. As each science does, geoethics should also be able to present an image of the world, pointing out the manner in which it can be understood, investigated, designed, and experienced.

    Beschreibung: At Vulcano (Aeolian Islands, Italy), different measurement methods have been developed for more than 30 years and models were formulated to account for the real time evolution of the actual solphataric activity. The results of a long term monitoring of surface temperature and of CO2 flux from soil, reviewed in a multidisciplinary framework, are presented here. These two parameters, monitored at the ground surface, highlighted local variations of the hydrothermal release and the time series of data showed in several instances, different range of values. The background and anomalous ranges defined by this long term monitoring are robust by a statistical point of view. The long term data-series offered a useful tool to verify conceptual framework and to better define the natural hazard evaluation integrating “classical” and “new” investigation techniques. Moreover, La Fossa area lays in a geodynamic context with active seismo- tectonic processes, frequently perturbing the pressure field of the hydrothermal system under investigation. Any perturbation in the pressure state variable (P) of the system, results in an excited state of its components and a relevant transfer of energy and mass towards the surface starts to counterbalance the perturbation. The continuous monitoring of surface temperature reveals the effects of the forces guiding the heat flows whereas the space variation of temperature indicates the rising paths of hydrothermal and magmatic fluids. The occurrence of new fumaroles and mofetes, or even changing emission rates of fluids by these vents, rises questions about the evolution of the equilibrium state of buried hydrothermal system, or about changing physical condition of overburden rocks. The conceptual framework suggesting the potential of our time series of field data is that a rock body, can be seen as a multiphase geochemical system where the fluid phases play a crucial role in defining the physical changes of the body and its response to the different forces acting on it. The changes of pore pressure depend on the balance between gas phases production and gas leaked out from a geochemical system. Analyses of fluxes at the system boundaries can give information on the equilibrium of the interacting geospheres. Even if playing variables are too many, some specific compounds and parameters can be selected as indicators of the state of the system.#

    Beschreibung: We present soil temperature data from a peripheral fumarole emission of Mt Etna at the top end of a radial fracture called Bottoniera. This area lies in the northern flank of the volcano (2,500m a.s.l.), and was interested by fissure eruption during 2002/2003. In the steam heated soil lying around the fumarole release, a shallow vertical profile has been monitored from October 2009 to September 2012. We estimated the local surface heat flux and compared its time variations to the eruptive activity occurred during the monitoring period. The eruptive vents were located on the opposite flank, (〉3200m a.s.l.), far about 4km. The heat flux from this peripheral emission has been highly influenced by the eruptive activity. Its time variations are correlated to the variable rates of products emitted from January 2011 to April 2012. Different ranges of heat flux values have been associated to the pre-eruptive phase, to the productive eruption period and to the end of this eruptive cycle. The decrease of heat flux was registered before the end of the eruptive cycle. The continuous thermal monitoring revealed in real time that ascending magma through the active conduits is the heating bottom source of the heat flux dispersed by a complex network of active fractures present in this area. The recorded data suggest the steam heated soil around fumaroles vents as a possible new investigation field for a low cost monitoring of the local variation in the structural weakness of the apparatus. Extending this thermal monitoring to the other steaming grounds of this complex volcanic system we could also follow variations of the fluid circulation paths and obtain direct information about local pore pressure changes. A multivariate analysis of recorded data could suggest, which part of this complex apparatus is being involved, time by time, with the ongoing evolution. It would contribute to the evaluation of flank instability caused by physical changes occurring on the network of active fractures, and inferred by multidisciplinary investigations (such as deformation patterns, tectonic lineaments and geochemical features of underground waters and diffuse gas emissions).

    Beschreibung: Questo lavoro propone quattro percorsi geoturistici a tema nello straordinario mondo dei paesaggi vulcanici campani, lungo la costa del Tirreno, per scoprire la notevole geo-diversità e biodiversità che in un territorio dal ricco patrimonio naturale, scientifico e culturale quale la Campania, è possibile sperimentare. Il nostro percorso è un viaggio di scoperta con occhi nuovi che, attraverso l’osservazione delle morfologie e delle peculiarità naturalistiche degli ambienti vulcanici proposti, ci permette di comunicare con la natura che svela i suoi segreti a chi entra in sintonia con essa, risvegliando emozioni. Questo lavoro ha altresì come obiettivo la divulgazione delle caratteristiche geologico- naturalistiche dei molteplici ambienti dei rilievi vulcanici campani, anche perché la crescente frequentazione dei luoghi è spesso accompagnata da scarsa informazione scientifica disponibile relativa ai percorsi effettuati, e dalla volontà di una fruizione più consapevole, che possa condurre ad azioni di difesa di un territorio non ancora del tutto adeguatamente conosciuto (Hose, 2012).

    Beschreibung: In areas of active but dormant volcanoes, people need to know some basic facts: What volcano is going to erupt? What kind of eruption will occur? When and where will it take place? Why will it occur? And, also, what should citizens do to save themselves and their families? Communications travel in a complex network of connections among individuals and groups. If the main stakeholders involved do not work together to deliver coherent and complementary messages, the transmitted message may be contradictory, or inconsistent. Misunderstanding and confusion will take over, increasing rather than mitigating the risk. For this reason, citizens need to turn to scientists and research institutes working in hazardous areas as key interlocutors for matters concerning basic information concerning volcanic hazard. At the same time, scientists in charge of volcano surveillance, together with emergency managers, media, and public officials, have the duty to answer citizens’ need for information, exploring multiple channels and languages to communicate effectively. The present chapter analyzes some systematic studies and multidisciplinary research projects on this topic that have been carried out in recent years. It also points out an analysis of the public use of the Vesuvius Observatory museum, which is a reference information point for people living in the Naples (Italy) area and exposed to volcano hazard.
