    Description: QUESTO VOLUME RACCONTA UNA STORIA DI CAMBIAMENTI. Da un lato i cambiamenti del nostro pianeta, un ambiente vivo e in continua trasformazione; dall’altro, i cambiamenti nel modo di pensare, vedere e spiegare il mondo che, nell’arco di duemila anni, hanno guidato l’uomo nella comprensione dei meccanismi che regolano l’evoluzione della Terra. Il risultato di questo lungo percorso è la teoria della Tettonica delle Placche, una delle più importanti rivoluzioni scientifiche del XX secolo. La sua enunciazione ha coronato un’epoca d’oro per le Scienze della Terra. Accolta inizialmente con scetticismo, talvolta apertamente osteggiata, è stata accettata da un’intera generazione di scienziati che hanno fatto proprie le idee sulla deriva dei continenti, ponendo le basi per il cambiamento del modo di studiare e comprendere la dinamica della Terra: dalla visione di un pianeta statico, cristallizzato nelle sue forme, si è passati alla consapevolezza di vivere su un pianeta dinamico, continuamente rimodellato dalla tettonica globale. La teoria della Tettonica delle Placche è in grado, da sola, di spiegare fenomeni apparentemente inconciliabili: l’attività sismica, l’orogenesi, la disposizione dei vulcani, il magnetismo delle rocce, la formazione di strutture come le fosse oceaniche e gli archi vulcanici, la distribuzione e la forma dei continenti, il riaggiustamento isostatico postglaciale, la distribuzione geografica delle faune e flore fossili e la sorprendente struttura dei fondali oceanici. In questo volume percorriamo un lungo viaggio attraverso le intuizioni e le scoperte degli scienziati che, più di tutti, hanno contribuito alla formulazione della teoria della Tettonica delle Placche. I geografi del XVI secolo avevano notato, per primi, la somiglianza tra i margini dei continenti che si affacciano sull’Oceano Atlantico; nei secoli successivi sono state formulate molte ipotesi per spiegare queste caratteristiche della superficie e comprendere come siano correlate con la struttura interna della Terra, fino ad arrivare all’ipotesi sulla deriva dei continenti di Alfred Wegener. All’inizio del XX secolo erano già stati raccolti tutti gli elementi per una prima formalizzazione della teoria. Ma saranno la seconda guerra mondiale, prima, e la guerra fredda, dopo, a fornire l’opportunità per studiare in modo approfondito i fondali oceanici e per realizzare le prime reti sismiche globali. I nuovi dati raccolti forniranno le evidenze più schiaccianti a sostegno della Tettonica delle Placche. Con l’avvento del nuovo millennio, l’attenzione di molti scienziati si è rivolta allo studio dei pianeti extraterrestri in cerca dei segni di attività tettonica. Oggi sappiamo infatti che ha avuto un ruolo fondamentale nella comparsa della vita sulla Terra: l’individuazione di questi segni sarà centrale per la ricerca di mondi alieni che possano aver ospitato, o potranno ospitare, la vita.

    Description: Novel measurement technologies, additional sensors and increasing data processing capacities offer new opportunities to answer some of the currently most pressing societal and environmental questions. They also contribute to the fact that the available data volume will continue to increase. At the same time, the requirements for those providing such data rise and the needs of users to access it. The EPOS Delivery Framework aims to support this endeavour in the solid Earth domain by providing access to data, products, and services supporting multidisciplinary analyses for a wide range of users. Based on this example, we look at the most pressing issues from when data, products, and services are made accessible, to access principles, ethical issues related to its collection and use as well as with respect to their promotion. Among many peculiarities, we shed light on a common component that affects all fields equally: change. Not only will the amount and type of data, products, and services change, but so will the societal expectations and providers capabilities.

    Description: This research was inspired by an old stereoscopic viewer from the early 1900s, containing 42 glass slides depicting scenes from two Italian earthquakes that struck Southern Calabria and Eastern Sicily in the years 1894 and 1905, causing hundreds of deaths, but whose memory was blurred by the subsequent, great earthquake of the Messina Straits of December 28, 1908. The sequence of three-dimensional images shown by the viewer gave a deep and realistic visual impact to scenes of collapses, debris, and victims, arousing feelings of dismay. In this work, we describe the viewer apparatus; the places depicted in the stereoscopic plates, and the seismic phenomena that caused the disasters. But above all, we investigate the social and cultural aims that pushed to show the effects of local earthquakes through this kind of primitive multimedia mechanism. We exclude that the viewer, with its photographic equipment, was merely an instrument of entertainment. We rather assume that it carried out an educational task. The repetition of the sequence of tragic images of earthquakes through the stereoscopic viewer had the purpose of contributing to give awareness of the looming seismic risk and to accept rationally those recurring disasters.

    Description: The choices of a geoscientist while carrying out his/her activity are always accompanied by ethical implications, because they can have a strong impact on the population, the natural environment, the economy, the landscape and the cultural resources of the affected area. It is not uncommon for a geoscientist to be faced with ethical dilemmas that are problems with a difficult solution, since options to solve such dilemmas will have negative consequences. How does one make a choice in these circumstances? What is the ethical duty of geoscientists and what has to be their professional attitude? In which cases do they have the duty to take action or the duty to not act (duty of omission)? A brief review of the concepts formulated by philosophers in reference to ethics can serve to provide some answers to the above questions and to understand how geoscientists can best serve society.

    Description: This work is intended as a short introduction to social science literature, with the aim of critically analyzing some of the main theoretical paradigms, the most important concepts and research themes and their relevance in the context of policy making processes. The consolidation of the risk studies paradigm as well as the emergence of risk governance as an autonomous and multidisciplinary field of research owes much to the fundamental contribution of social sciences, which is the subject of this paper. The international scientific community has recognized the role of social sciences for some time, stressing that the connection and comparison between different knowledge is essential to achieve a single objective, namely the protection of human health, the environment and the communities and social groups exposed to risks. The strong overlap between the physical and material dimensions of risk and social, psychological and political dimensions inevitably entailed the need to overcome the impasse of reductionist explanations and the idea of self-sufficiency in the individual disciplines [Horlick Jones & Sime, 2004], which has also been the subject of epistemological reflection for some time in other fields [Morin, 2000]. However, one should point out that this extension of the field of risk analysis, today including social science and humanities [SSH] has not always been easy, nor bloodless. The full acceptance of social sciences in risk assessment, management and communication issues has required a laborious recognition of the limitations of rationalist paradigm in resolving or mediating social conflicts - sometimes dramatic - linked to the emergence of "new" risks, especially those related to nuclear energy, pollution and health. Numerous major catastrophic events, such as the fire at the Sellafield nuclear power plant in 1957, the foetal malformations caused by Talidomide in the early 1960s, the terrible consequences of methylmercury pollution in Minamata Bay in Japan at the end of the same decade, the evacuation of Love Canal from toxic waste, but above all, the nuclear accidents on Three Mile Island in 1979 and Chernobyl in 1986 have created a climate of widespread and justified public concern, which has often been accompanied by growing hostility towards science and technology, as these are increasingly seen as a source of incalculable, irreversible and catastrophic risks. In addition, disasters such as Vajont disaster in 1964, the Tangshan earthquake in 1976, the Indian Ocean Tsunami in 2004, Hurricane Katrina in 2005 and the Japan earthquake in 2011 showed that the extent of the damage was in many cases linked to wrong human decisions, making the distinction between anthropogenic and natural risks much more fades and conventional. In such a context, the need to provide organic and consistent responses to risks has made it necessary to integrate several disciplines, both in terms of multidisciplinarity (in which each discipline deals with a particular aspect of the problem in cooperation with the others) and transdisciplinarity (which integrates in a single approach theoretical and methodological elements of the different disciplinary knowledge) [Horlick Jones & Sime, 2004]. This dialogue, which presupposes a reflection on the epistemological foundations of the different disciplines, and the attempt to integrate concepts and definitions, is fundamental for assessing and informing political decisions on risks [Althaus, 2005], as well as the need to reconcile the scientific cultures of the so-called hard science (engineering, physics, epidemiology) with those of soft scienze as SSH + (anthropology, sociology, psychology) [Jasanoff, 1993]. In this context it emerged the new concept of risk studies: this term, which began to appear in the early 1980s, associated with research into the location of nuclear sites, was used in the early 1990s to identify a specific theoretical - disciplinary field aimed at analysing the social, political, economic and legal problems associated with risks [Krimsky, 1992]. Risk studies, which are nowaday characterized as a multidisciplinary and autonomous field that integrates different knowledge, are born precisely as a response to the emergence of risk perception as a social problem [Burgess, 2016], taking concrete form in the United States in the birth of different research groups with a strong multidisciplinary vocation.

    Description: Humans are recognized as a “geological force”, capable of modifying natural environments, and in virtue of this prerogative they have an ethical responsibility towards the planet. Indeed, studying and managing the Earth system, exploiting its geo-resources, intervening in natural processes are actions that involve great responsibilities towards society and the environment, of which perhaps we, as geoscientists, are not sufficiently aware. Only by increasing the awareness of this responsibility, can we work with wisdom and foresight, and respect the balances that exist in nature while guaranteeing a sustainable development for future generations. In order to define acceptable solutions to current global challenges, we need to take into proper consideration the ethical and social aspects involved in geoscience issues. Geoethics was born to define a conceptual substratum of categories, useful as framework of reference for geoscientists, to help them develop a new way of thinking and interacting with the Earth system. Geoethics widens the cultural horizon of geoscience knowledge and contributes to orient scientists and society in the choices for responsible behavior towards the planet. The paper provides an overview of the emerging field of geoethics, focusing on theoretical and practical aspects, by showing the trajectory that has led to the current point of development of geoethics and suggesting some cues for thought for further advancements of ethical thinking in geosciences.

    Description: The themes addressed by geoethics are becoming central to all scientific debate. A growing number of scientists now consider geoethics as an effective tool to increase, in the scientific community and society as a whole, the awareness of local and global environmental problems that humanity faces. Geoethics deals with ethical, social and cultural aspects related to geosciences. Geoethics addresses fundamental issues such as the prudent and sustainable use of geo-resources, management of natural hazards, defence of geoheritage as a common value to be protected and enhanced. But above all, geoethics aims to raise, in the community of geoscientists, their awareness of responsibilities in conducting scientific and professional activity. In order to extend this awareness to the whole of civil society and also to foster the recognition of the usefulness of geosciences in daily life, geoscience communication should be recognized as a fundamental activity connected with scientific and professional work, since geoscience knowledge is a tool to contribute to the construction of social knowledge for human communities. But today what is the role played by geosciences in the scientific mass culture? Are the geosciences part of a collective “cultural heritage”? Do the publishing world and media offer adequate space to geosciences? Through the analysis of two Italian case studies, the authors highlight the critical features of the relationship between geoscientists and the media and try to suggest some actions that are useful to make the relationship between these two separate fields more functional, with the goal of bringing citizens closer to geosciences and increasing the awareness of the individual and collective responsibility towards the Earth.

    Description: In this paper, we describe the 1809 eruption of Mt. Etna, Italy, which represents one historical rare case in which it is possible to observe details of the internal structure of the feeder system. This is possible thanks to the presence of two large pit craters located in the middle of the eruptive fracture field that allow studying a section of the shallow feeder system. Along the walls of one of these craters, we analysed well-exposed cross sections of the uppermost 15–20 m of the feeder system and related volcanic products. Here, we describe the structure, morphology and lithology of this portion of the 1809 feeder system, including the host rock which conditioned the propagation of the dyke, and compare the results with other recent eruptions. Finally, we propose the dynamic model of the magma behaviour inside a laterally-propagating feeder dyke, demonstrating how this dynamic triggered important changes in the eruptive style (from effusive/Strombolian to phreatomagmatic) during the same eruption. Our results are also useful for hazard assessment related to the development of flank eruptions, potentially the most hazardous type of eruption from basaltic volcanoes in densely urbanized areas, such as Mt. Etna.

    Description: In recent decades, geophysical investigations have detected wide magma reservoirs beneath quiescent calderas. However, the discovery of partially melted horizons inside the crust is not sufficient to put constraints on capability of reservoirs to supply cataclysmic eruptions, which strictly depends on the chemical-physical properties of magmas (composition, viscosity, gas content etc.), and thus on their differentiation histories. In this study, by using geochemical, isotopic and textural records of rocks erupted from the high-risk Campi Flegrei caldera, we show that the alkaline magmas have evolved toward a critical state of explosive behaviour over a time span shorter than the repose time of most volcanic systems and that these magmas have risen rapidly toward the surface. Moreover, similar results on the depth and timescale of magma storage were previously obtained for the neighbouring Somma-Vesuvius volcano. This consistency suggests that there might be a unique long-lived magma pool beneath the whole Neapolitan area.

    Description: The Campi Flegrei caldera is a complex structure with a high population density, located west of the city of Naples. In addition of being an active volcano it is characterized by a high seismic hazard due to both Appennines regional earthquakes and to local earthquakes occurring during the bradyseismic crises. These unrest phenomena are characterized by slow ground vertical movements, particularly active in the central part of the caldera, and by a high number of low-magnitude earthquakes. In this context, the determination of the site transfer functions of the area has a strong relevance for the Civil Defense aimed to determine the hazard of the area. We have calculated the site transfer function with different techniques (H/V and Generalized Inversion technique) and have collected data on the local geology with the aim of correlating the site transfer functions with lithology and topography. This analysis has been performed on three areas: the Astroni crater, the Camaldoli hill and the Agnano plain. A future development will be to extend this analysis to the whole Campi Flegrei area.

    Description: The individuation of areas that are more likely to be affected by new events in volcanic regions is of fundamental relevance for the mitigation of the possible consequences, both in terms of loss of human life and material properties. Here, we describe a methodology for defining flexible high-detail lava-hazard maps and a technique for the validation of the results obtained. The methodology relies on: (i) an accurate analysis of the past behavior of the volcano; (ii) a new version of the SCIARA model for lava-flow simulation (based on the macroscopic cellular automata paradigm); and (iii) high-performance parallel computing for increasing computational efficiency. The new release of the SCIARA model introduces a Bingham-like rheology as part of the minimization algorithm of the differences for the determination of outflows from a generic cell, and an improved approach to lava cooling. The method is here applied to Mount Etna, the most active volcano in Europe, and applications to landuse planning and hazard mitigation are presented.

    Description: Mount Etna produces frequent eruptions from its summit craters and from fissures on its flanks. The flank fissures trend approximately radially to the summit, and are mainly concentrated in three rift zones that are located on the NE, S and W flanks. Many flank eruptions result from lateral magma transfer from the central conduit into fractures intersecting the flanks, although some eruptions are fed through newly formed conduits that are not directly linked to the central conduit. We analyzed the structural features of eruptions from 1900 to the present, one of the most active periods in the documented eruptive history of Etna, which comprised 35 summit and 33 flank events. Except for a small eruption on the W flank in 1974, all of the flank eruptions in this interval occurred on or near the NE and S rifts. Eruptions in the NE sector were generally shorter, but their fissure systems developed more rapidly and were longer than those in the S sector. In contrast, summit eruptions had longer mean durations, but generally lower effusion rates (excluding paroxysmal events characterized by very high effusion rates that lasted only a few hours). This database was examined considering the main parameters (frequency and strike) of the eruptive fissures that were active over the last ~2 ka. The distribution in time and space of summit and flank eruptions appears to be closely linked to the dynamics of the unstable E to S flank sector of Etna, which is undergoing periodic displacements induced by subvolcanic magma accumulation and gravitational pull. In this framework, magma accumulation below Etna exerts pressure against the unbuttressed E and S flanks, which have moved away from the rest of the volcano. This has caused an extension to the detachment zones, and has facilitated magma transfer from the central conduit into the flanks.

    Description: The terrestrial 3D Laser Scanning technique has been applied to analyse the surface roughness of pyroclastic deposits on volcanic surfaces at Mt. Etna. This technique allowed the construction of high accuracy digital elevation models of small surfaces, about 1 m across. Sampled surfaces differ for percentage of coverage and for grain size of the pyroclastic deposits. The change in grain size distribution for the pyroclastic unconsolidated deposits affects the surface roughness. The roughness of the site where the finest pyroclastic deposits occur is mainly governed by large scale wavelength morphology (Hurst exponent H = 0.77 for lengths larger than 16 mm). The other sampled surfaces have self-affine characters with low (0.15) to intermediate (0.35 - 0.38) Hurst exponents for lengths higher than 10 – 22 mm. Here we show results of the analysis of the surface roughness of the pyroclastic deposits emplaced during the 2001 and 2002-2003 eruptions at Mt. Etna. Grain size and thickness of pyroclastic deposits mainly control the overall roughness of such as volcanic surface.
