    La prevenzione dai rischi naturali: una questione (geo)etica e culturale (2017)
    Gruppo Editoriale L'Espresso spa
    Details
    Publication Date: 2017-04-04
    Description: In Italia non esiste una strategia di riduzione dei rischi naturali, che parta dall’educazione nelle scuole e dall’informazione alla popolazione, che preveda sistematicamente esercitazioni di emergenza, la pianificazione di interventi di rinforzo delle abitazioni, l’applicazione rigorosa delle normative edilizie, la delocalizzazione di edifici strategici e di impianti industriali a rischio. Al momento la prevenzione in Italia viene percepita soprattutto come declamazione di luoghi comuni e slogan, puntualmente rispolverati dopo ogni tragedia. Quali sono le ragioni profonde di una tale irrazionalità fatalistica che ignora la scienza? Il nuovo campo della geoetica può dare alcune risposte.

    International Association for Promoting Geoethics (IAPG): an update on activities (2016)
    European Geosciences Union
    Details
    Publication Date: 2021-06-25
    Description: The International Association for Promoting Geoethics (IAPG: http://www.geoethics.org) was founded on August 2012 to unite global geoscientists to raise the awareness of the scientific community regarding the importance of the ethical, social and cultural implications of geoscience research, education, and practice. IAPG is an international, multidisciplinary and scientific platform for discussion on ethical problems and dilemmas in Earth Sciences, promoting geoethical themes through scientific publications and conferences, strengthening the research base on geoethics, and focusing on case-studies as models for the development of effective and operative strategies. IAPG is legally recognized as a not-for-profit organization. It is a non-governmental, non-political, non-party institution, at all times free from racial, gender, religious or national prejudices. Its network continues to grow with more than 900 members in 103 countries, including 20 national sections. IAPG operates exclusively through donations and personal funds of its members. The results achieved since inception have been recognized by numerous international organizations. In particular, IAPG has obtained the status of affiliated organization by the International Union of Geological Sciences (IUGS), American Geosciences Institute (AGI), Geological Society of America (GSA), and the Geological Society of London (GSL). IAPG has enlarged its official relationships also through agreements on collaboration with other organizations, such as the American Geophysical Union (AGU), EuroGeoSurveys (EGS), European Federation of Geologists (EFG), Association of Environmental & Engineering Geologists (AEG), International Geoscience Education Organisation (IGEO), African Association of Women in Geosciences (AAWG), and others. IAPG considers publications as an indispensable activity to strengthen geoethics from a scientific point of view, so members are active in the publication of articles and editing of books on Geoethics with a peer-review process. Moreover, IAPG organizes sessions/symposia on geoethics in national and international congresses, thus encouraging a wide participation of the scientific community in the discussion on geoethical topics. This presentation provides an update on new results and numerous ongoing activities carried out by the IAPG with a brief look to future initiatives.

    Geoethics: A framework for the management of the geosphere and geo-risks (2016)
    INGEMMET
    Details
    Publication Date: 2017-04-04
    Description: In a world where natural disasters are increasing and there is an urgent demand for an ethics of prevention, management and communication, a framework of ethical principles and standards for orienting geoscientists in conducting their professional activity becomes fundamental. The defense against geo-risks involves many actors with different roles. Good relationships between them is necessary to assure efficiency while facing potential natural disasters. Defining a (geo)ethical framework of values means to create a solid base on which a proper management of georisks can operate. By defining roles and responsibilities, Geoethics is a valuable reference to work in this direction and to improve the resilience of human community to disasters.

    Geoethics: Ethical, social, and cultural values in geosciences research, practice, and education (2016)
    Geological Society of America
    Details
    Publication Date: 2017-04-04
    Description: All geoscience practices have evident repercussions on society. Geoscientists have knowledge and skills to investigate, manage, and intervene on the geosphere, defined as the component of the Earth system constituted by the land surface, the solid Earth, the hydrosphere, the cryosphere, and the atmosphere. This implies ethical obligations. The adoption of ethical principles is essential if geoscientists want to best serve the public good. Ethical responsibility by all geoscientists requires a more active role while interacting with society. Geoethics, which investigate the ethical, social, and cultural implications of geoscience research, practice, and education, represents a new way of thinking about and practicing earth sciences, focusing on issues related to the relationship of the geoscientist with the self, colleagues, and society in the broadest sense. In this paper, we define some of the main values relevant to geoethics.

    ENVRI PLUS project: Developing an ethical framework for Environmental and Earth System Research Infrastructures (2016)
    European Geosciences Union
    Details
    Publication Date: 2017-04-04
    Description: ENVRI PLUS is a Horizon 2020 project bringing together Environmental and Earth System Research Infrastructures (RIs), projects and networks with technical specialist partners to create a more coherent, interdisciplinary and interoperable cluster of Environmental Research Infrastructures across Europe (http://www.envriplus.eu/). One theme of the project deals with the societal relevance and understanding, and within that theme an entire work-package (WP) aims at developing an ethical framework for RIs. Objectives of this WP are: • increase the awareness of both the scientists and the public on the importance of ethical aspects in Earth sciences; • establish a shared ethical framework of reference, to be adopted by RIs governing bodies; • increase the awareness of RIs management and operational levels and of the individual involved scientists on their social role in conducting research activities and research work environment; • assess the ethical and social aspects related to the results achieved and deliverables released within the project. The ongoing activities include: • reviewing the state of art on ethical issues useful for the goals of the project (collection and analysis of materials already existing within scientific organizations, institutions all over the world); • the creation of a questionnaire, through which to investigate how each RI participating in ENVRI PLUS faces ethical issues in relation to its activities, and so to understand the level of perception that researchers and technicians involved in the project have on the ethical implications of their scientific activities; • the definition of ethics guidelines to be used by partners for building their policies and their own codes of conduct; • the elaboration of an ethical label template to characterize each product of the project, that partners will be able to use in order to give essential information about the ethical and social implications of their products; • the dissemination of all the results of the previous activities on websites and social networks, so that they are suitable for the public. ENVRI PLUS is the first European project in which ethics applied to geosciences find space as a fundamental issue, at the base of scientific activities.

    Geoethics: a new perspective for geosciences (2016)
    GeoEcoMar, Bucharest (Romania)
    Details
    Publication Date: 2017-04-04
    Description: In recent years, the need to develop an ethical reflection on the values that are at the basis of geoscience research and practice has arisen powerfully. Studying the Earth system, managing the land, geo-engineering the environment, exploiting its geo-resources, and altering natural processes are actions that involve great responsibilities towards oneself, colleagues, society and the environment, of which perhaps we, as geoscientists, are not sufficiently aware.

    Earth is speaking: listen her! On-line questionnaire about anomalous geological and biological phenomena (2015)
    Details
    Publication Date: 2017-04-04
    Description: Earthquakes can be associated with non-seismic phenomena which may manifest many weeks before and after the main shock. These phenomena are characterized by ground fractures and soil liquefactions at surface often coupled with degassing events, chemical alterations of water and soils, changes in temperature and/or waters level in the epicentral area. Further manifestations include radio disturbances and light emissions. On the other hand, anomalous behavior of animals has been reported to occur before environmental changes. The co-occurrence of several phenomena may be considered as a signal of subsurface changes, and their analysis may be used as possible forecast indicators for seismic events, landslides, damages in infrastructure (e.g., dam) and groundwaters contamination. In order to obtain an accurate statistical analysis of these factors, a pre-crisis large database over a prolonged period of time is a pre-requisite. To this end, we elaborated a questionnaire for the population to pick up signs about anomalous phenomena like as: animal behavior, geological manifestations, effect on vegetation, degassing, changes on aquifers, wells and springs. After the January 25, 2013, mainshock (ML 4.8) in the Garfagnana seismic district, the Bagni di Lucca Municipality was selected as pilot site for testing this questionnaire. The complexity, variety and extension of this territory (165 kmq) sound suitable for this project. Bagni di Lucca is located in the southern border of the Garfagnana seismogenic source, characterized by the carbonate Mesozoic sequences and the Tertiary terrigenous sedimentary deposits of the Tuscan Nappe. The questionnaire was published on Bagni di Lucca web site (https://docs.google.com/file/d/0Bzw3vOYX47XoTGltTVJRbkJuajA/edit) in collaboration with Municipal Commitee, Local Civil Protection and Local Red Cross, and sent by ordinary mail to the citizenry. It is possible to answer to the questionnaire, also anonymously, direct on line (https://docs.google.com/forms/d/1LVNVQFzMoJJfNxp2eSPAc4pcwj4_qIdbAnvbCWGyXy8/viewform?pli=1), calling the Local Civil Protection or Local Red Cross, and by mail. In a second time, an application for Smartphone and Tablets will be developed to allow a faster reply. The questionnaire, constituted by eleven questions and organized in four macro-themes (i.e. animal behavior, geological factors, vegetation anomalies and hydrogeological changes) has been published in June 2013 and will remain on-line for several years. Indeed, the social perception is not fully trustworthy during and soon after an earthquake. So far this is the first attempt to acquire data during quiescent times for comparison with post-seismic ones. This approach may provide clues to identify phenomena properly linked to the event. This questionnaire can be a useful tool to educate population not only about earthquake precursors but also to recognize the "Earth language". Submitted testimonies will be statistically analyzed evidencing the specific responses to the different phenomena in space and time. On the basis of obtained results the questionnaire project could be extended to national level.

    Laboratory activities for seismic and volcanic hazards education: a challenge for scientists (2015)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: Balanced information and education are fundamental prerequisites for risk prevention and preparedness. Among others, children embody our best chance to implant appropriate behaviors that will be recalled during hazardous situations and to involve adults according to a knowledge chain reaction. In this work, scientists challenge their communication skills to built a set of hands-on and learn-by-play based laboratory activities, for primary and secondary schools, addressing three major issues: (1) the location of earthquakes and volcanoes on Earth; (2) earthquakes and eruptions mechanisms; (3) earthquakes unpredictability. Students are asked to place volcanoes and earthquakes epicenters (issue 1) on a wooden plate puzzle according to Plate dynamics. To addresses eruption mechanisms (issue 2) and related hazard, we use backing soda forced blowing out from a volcano vent and suggest that a pyroclastic flow is fast, it can spread over a large area and raise high up to the stratosphere. Earthquake mechanisms (issue 2) are discussed describing the energy buildup, release, and transfer, using a wooden sticks bendand- break analogy. The display of acoustic waves caused by the breakage in different situations allows understanding of both the rupture energy and the wave attenuation. Earthquakes occurrence (issue 3) is addressed using steadily pulled blocks sliding on a frictional surface, where pins simulate asperities. These activities were tested, involving thousands of students. Discussions with students and teachers and the analysis of the answers to specific questionnaires gave us confidence that we proposed proper tools to raise risk awareness

    Shallow subsurface imaging of the Piano di Pezza active normal fault (central Italy) using high-resolution refraction and electrical resistivity tomography coupled with time-domain electromagnetic data (2015)
    Miscellana INGV
    Details
    Publication Date: 2017-04-04
    Description: The Piano di Pezza fault (PPF) is the north-westernmost segment of the 〉20 km long Ovindoli-Pezza active normal fault-system (central Italy). Although existing paleoseismic data document high vertical Holocene slip rates (~1 mm/yr) and a remarkable seismogenic potential of this fault, its subsurface setting and Pleistocene cumulative displacement are still unknown. We investigated the shallow subsurface of a key section of the PPF using seismic and electrical resistivity tomography coupled with time-domain electromagnetic measurements (TDEM). We provide 2-D Vp and resistivity images showing details of the fault structure and the geometry of the shallow basin infill down to 35-40 m depth. We can estimate the dip and the Holocene vertical displacement of the master fault. TDEM measurements in the fault hangingwall indicate that the pre-Quaternary carbonate basement may be found at ~90-100 m depth.

    Description: "Is there still basic research in the Earth Sciences?" In recent decades, leading researchers, policy makers and science operators have shown that there is no sustainable development without adequate funding programs of basic research. Whoever is approaching to world of scientific research in should be aware of the fundamental elements of the debate on these topics, as well as the steps that have most influenced the evolution of the concept of scientific research in the last hundred years. This note is meant to represent only a starting point for further readings and attempts at giving a brief overview of the evolution, over a century, of the concepts of basic and applied research, and their relation to society: from "academic" to "post-academic" science and from the "linear model" to the idea of a much more complex process that could describe the impact of science on society.

    Perception of risk for volcanic hazard in Indian Ocean: La Réunion Island case study. (2015)
    Springer
    Details
    Publication Date: 2020-02-24
    Description: In 2011 a research project on volcanic risk assessment at La Réunion Island (Project Aléa, Institute de Physique du Globe de Paris, France) was conducted in order to determine more efficient strategies to manage future volcanic crises. The project included the evaluation of volcanic scenarios through field and historical data analysis, as well as a survey on volcanic risk perception in resident population. A clear scientific information and an effective communication with public play a crucial role in risk mitigation strategies. In particular, the evaluation of the public perception during both volcanic crises and dormant periods is an important element in developing actions focused on specific social and cultural contexts. A questionnaire was developed based on the ones used in similar researches conducted on Italian active volcanoes. Items were designed to measure variables connected with personal perception of hazard and risk, trust in mitigation actions and in information received about these aspects. In addition, specific items related to the peculiarities of La Réunion Island environment were included. A total of 2,000 questionnaires were distributed taking into account factors such as the proximity to the volcano and the involvement of communities in recent volcanic emergencies. Main results coming out from this survey, if on the one hand show an adequate residents’ perception of natural hazards, on the other hand highlight their poor knowledge of the island’ active volcano, a similar lacking knowledge of emergency plan for volcanic crises, but also a high confidence in scientists to provide accurate and reliable information on volcanic risk and hazards in contrast with Local Authorities. Remarkable findings of this study assess some key elements that should be considered by the institutions in charge for defining policies aimed to volcanic risk mitigation and management of future volcanic crises.

    A 2-D FEM thermal model to simulate water flow in a porous media: Campi Flegrei caldera case study (2015)
    Copernicus Publications
    Details
    Publication Date: 2017-04-04
    Description: 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.

    Description: L’Italia è un paese geologicamente giovane e pertanto in continua evoluzione. Il suo territorio è fatto di paesi arroccati sui rilievi o distesi nei fondovalle, di fragili e preziosi centri storici, di città cresciute spesso in modo disordinato, dove alla vetustà del patrimonio monumentale del passato si è progressivamente affiancata la modernità delle costruzioni più recenti. Questo determina per gran parte del territorio nazionale una costante esposizione di persone, oggetti e attività ad elevati livelli di rischio. Ciononostante in Italia ancora manca un’adeguata cultura del rischio, che porti ad una maggiore consapevolezza della fragilità del territorio e del valore delle azioni di prevenzione, indispensabili per limitare gli effetti negativi di un fenomeno naturale. Questa lacuna comporta un’impreparazione a fronteggiare anche gli eventi naturali più comuni e frequenti.

    The Meaning of Geoethics (2015)

    Details
    Publication Date: 2017-04-04
    Description: 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.

    Details
    Publication Date: 2017-04-04
    Description: This book is one out of 8 IAEG XII Congress volumes, and deals with education and the professional ethics, which scientists, regulators, and practitioners of engineering geology inevitably have to face through the purposes, methods, limitations, and findings of their works. This volume presents contributions on the professional responsibilities of engineering geologists; the interaction of engineering geologists with other professionals; recognition of the engineering geological profession and its particular contribution to society, culture, and economy; and implications for the education of engineering geologists at tertiary level and in further education schemes. Issues treated in this volume are: the position of engineering geology within the geo-engineering profession; professional ethics and communication; resource use and re-use; managing risk in a litigious world; engineering and geological responsibility; and engineering geology at tertiary level. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: Environment, processes, issues, and approaches.

    Geoethical aspects in the natural hazards management (2015)
    Springer
    Details
    Publication Date: 2017-04-04
    Description: The defence against natural hazards involves many actors with different roles: geoscientists, decision makers, local authorities, mass media, citizens. A proper management of georisks requires that each role is well-defined and governed by shared operational protocols, especially during the emergency phase, so that overlapping and misunderstanding don’t jeopardize population safety and economic activities. To achieve good results in this direction, it is necessary to undertake a careful evaluation of the limits and expectations of each component of society and the respect of legitimate aspirations and prerogatives. An effective defence system against natural hazards should be planned rationally and based on scientific data, in order to avoid alarmism among citizens, misleading sensationalism by media, careless decisions by politicians, as well as approximation in managing different phases of the risk cycle. Taking into consideration geoethical aspects related to natural hazards can be helpful to make geoscientists aware of their responsibilities towards society and to clarify the role they can play in the interaction with other actors, aiming at more efficacious actions for georisk mitigation.

    Preface: Approaches and methods to improve risk management in volcanic areas (2015)
    Details
    Publication Date: 2017-04-04
    Description: Active volcanoes can generate multiple types of geological hazards. Besides syneruptive threats (e.g., lava, pyroclastic flows or ash fall), other adverse events such as landslides or lahars can occur at any time. To manage these threats efficiently, three key objectives must be jointly addressed: (1) improving prevention tools, through the collection and acquisition of data on hazards and risks, and its dissemination as maps and scenarios; (2) improving crisis management capabilities, based on monitoring and early warning systems, but also reliable communications systems; and (3) reducing people’s vulnerability and developing recovery and resilience capabilities after an event has occurred. The special issue “Approaches and methods to improve risk management in volcanic areas” presents research results focusing on these three objectives. It demonstrates the utility of addressing them jointly, and particularly examines the case of volcanoes where little knowledge is available. These results were presented at the conference Integrated Approaches for Volcanic Risk Management (Hohenheim University, Stuttgart, 11/12 September 2012) of the European MIAVITA (MItigate and Assess risk from Volcanic Impact on Terrain and human Activities) project.

    A Methodology for a Comprehensive Probabilistic Tsunami Hazard Assessment: Multiple Sources and Short-Term Interactions (2015)
    Details
    Publication Date: 2017-04-04
    Description: We propose a methodological approach for a comprehensive and total probabilistic tsunami hazard assessment (TotPTHA), in which many different possible source types concur to the definition of the total tsunami hazard at given target sites. In a multi-hazard and multi-risk perspective, the approach allows us to consider all possible tsunamigenic sources (seismic events, slides, volcanic eruptions, asteroids, etc.). In this respect, we also formally introduce and discuss the treatment of interaction/cascade effects in the TotPTHA analysis and we demonstrate how the triggering events may induce significant temporary variations in short-term analysis of the tsunami hazard. In two target sites (the city of Naples and the island of Ischia in Italy) we prove the feasibility of the TotPTHA methodology in the multi-source case considering near submarine seismic sources and submarine mass failures in the study area. The TotPTHA indicated that the tsunami hazard increases significantly by considering both the potential submarine mass failures and the submarine seismic events. Finally, the importance of the source interactions is evaluated by applying a triggering seismic event that causes relevant changes in the short-term TotPTHA.

    Description: Il secondo convegno congiunto ACNP / NILDE: ecosistemi per la ricerca è stato ospitato dal 22 al 23 maggio 2014 dall’Università di Trieste. Sotto gli auspici della stessa Università di Trieste e degli altri enti di ricerca del Friuli Venezia Giulia1 sono stati affrontati in un’ottica internazionale i temi del rapporto tra cataloghi collettivi e servizi interbibliotecari, e il più generale ambito dei servizi bibliografici per la ricerca scientifica. ACNP e NILDE possono essere considerati un vero e proprio ecosistema. Le biblioteche e i bibliotecari collaborano tra di loro in maniera reciproca e secondo modalità interconnesse, offrendo agli utenti servizi sempre più evoluti e dinamici. Questo ecosistema, essendo aperto, mette i propri servizi a disposizione della ricerca scientifica in senso generale. Il convegno di Trieste ha offerto l’occasione di investigare e proporre soluzioni innovative, interconnessioni e relazioni nuove e più proficue. Il convegno ha presentato alcune rilevanti esperienze internazionali in tema di servizi interbibliotecari e cataloghi collettivi e la prosecuzione di attività che erano state proposte come spunti di ispirazione nel convegno precedente2 inoltre si sono condotte delle riflessioni sulle nuove esigenze dell’utenza. Una ultima parte è dedicata alla illustrazione degli sviluppi tecnici e le prospettive future di ACNP e di NILDE. Hanno partecipato all’evento oltre 200 colleghi italiani e stranieri ed i relatori dei 18 contributi provenivano da Italia, Germania, Austria, Grecia, Slovenia e Stati Uniti. Il carattere di confronto e di condivisione delle esperienze tipico della realtà partecipativa di ACNP e NILDE, è emerso anche in questa occasione nella tavola rotonda - di cui viene riportato un resoconto dettagliato - che ha affrontato il tema della valutazione della ricerca dal punto di vista delle biblioteche. Inoltre, la molto partecipata sessione poster ha ospitato 13 lavori- anch’essi riportati nel volume - incentrati oltre che su ACNP e NILDE anche sul tema ricerca e sistema biblioteca, dando ottimi spunti di partecipazione, dialogo e confronto sulle diverse realtà in cui operiamo.

    Coherent Control of Stimulated Emission inside one dimensional Photonic Crystals: Strong Coupling regime (2015)
    InTech - open science, open minds
    Details
    Publication Date: 2017-04-04
    Description: The present book chapter discusses the stimulated emission, in strong coupling regime, of an atom embedded inside a one dimensional (1D) Photonic Band Gap (PBG) cavity which is pumped by two counter-propagating laser beams. Quantum electrodynamics is applied to model the atom-field interaction, by considering the atom as a two level system, the e.m. field as a superposition of normal modes, the coupling in dipole approximation, and the equations of motion in Wigner-Weisskopf and rotating wave approximations. In addition, the Quasi Normal Mode (QNM) approach for an open cavity is adopted, interpreting the local density of states (LDOS) as the local density of probability to excite one QNM of the cavity; and therefore rendering this LDOS dependent on the phase difference of the two laser beams. In this book chapter we demonstrate that the strong coupling regime occurs at high values of the LDOS. In accordance with the results of the literature, the emission probability of the atom decays with an oscillatory behaviour, so that the atomic emission spectrum exhibits two peaks (Rabi splitting). The novelty of this book chapter is that the phase difference of the two laser beams can produce a coherent control of both the oscillations for the atomic emission probability and, as a consequence, of the Rabi splitting in the emission spectrum. Possible criteria to design active delay lines are finally discussed.

    Uno sguardo d'insieme sugli eventi geologici e climatici che caratterizzano l'Olocene nell'area baltica e mediterranea (2015)
    Details
    Publication Date: 2017-04-04
    Description: L'Olocene è l'epoca geologica più recente e si estende convenzionalmente da circa 11.700 anni fa fino ai giorni nostri. È in questo periodo che appaiono le più importanti civiltà umane. Pertanto, a partire dall'Olocene, i cambiamenti ambientali, i fenomeni naturali e i pericoli ad essi associati diventano determinanti per il loro impatto sugli eventi storici, spesso andando a sovrapporsi alle vicende umane e influenzando l'ascesa o il declino delle civiltà stesse. Questo lavoro vuole offrire una panoramica sulle condizioni geologiche, climatiche e paleogeografiche che caratterizzano l'Olocene nell'Europa settentrionale e dell'area mediterranea, per fornire elementi utili ad inquadrare in modo più accurato l'ipotesi formulata da Felice Vinci sulla migrazione delle popolazioni del Baltico verso il Mediterraneo nell'Età del Bronzo, alla fine del "Optimum climatico". Nello studio vengono sintetizzate informazioni sulle variazioni glacio-eustatiche e sul sollevamento isostatico olocenico che hanno caratterizzato l'Atlantico settentrionale, il Mare del Nord, la Scandinavia ed il Mar Baltico. Inoltre, vengono illustrati dati su terremoti, eruzioni vulcaniche e probabili tsunami che interessarono la regione del Mediterraneo ed il Nord Europa nell'Olocene: tali eventi catastrofici potrebbero in qualche modo aver favorito lo spostamento e l'insediamento di popolazioni scandinave provenienti dal nord nelle aree mediterranee, anche in virtù dell'indebolimento demografico e socio-economico delle popolazioni indigene. I dati e le informazioni sono stati attinti dalla letteratura scientifica, riportata in bibliografia. Tuttavia è importante evidenziare che la quantità di informazioni disponibili sugli argomenti trattati in questo lavoro è rilevante e talvolta teorie sviluppate a partire dagli stessi dati si mostrano in conflitto. Il confronto tra l'area mediterranea e la regione baltica (una delle quali potrebbe essere stata il teatro degli eventi raccontati da Omero) potrebbe rivelarsi utile per individuare tracce, evidenze e prove di eventi geologici catastrofici nella narrazione omerica e per fornire nuovi elementi sui luoghi in cui i poemi sono ambientati, delineando spunti di discussione e di approfondimento per studi scientifici che possano verificare o confutare l'ipotesi formulata da Vinci .

    Non-geodetic” approaches in the analysis of terrestrial CDGPS data for the retrieval of the atmospheric precipitable water at local scale during severe weather phenomena (2015)
    Details
    Publication Date: 2017-04-04
    Description: Precipitable water (PW) derived from the CDGPS (Continuous Differential Global Positioning System) zenith tropospheric delay (ZTD) is evaluated through comparison of three procedures: using GPT (Global Pressure and Temperature) and GPT2 global models as well as observed data. The results show that the difference between PW retrieved from models (GPT and GPT2) and PW obtained by observed meteorological data, at least for sites and period observed in this paper, is also a function of the position of the station. The short period considered does not allow for any consideration of possible intra-annual or annual periodicity. The analysis of the residuals between observed PW and modeled PW shows a peak before the rain event.

    Evaluation of the atmospheric precipitable water at local scale during extreme weather using groundbased CGPS measurements (2015)
    Details
    Publication Date: 2017-04-04
    Description: Global Positioning System (GPS) has demonstrated its ability to monitor the atmospheric water vapor content with an accuracy comparable to other techniques and means of measurements (e.g. radio soundings, microwave radiometers), even with good time resolution and under all meteorological conditions. The nowadays extensive use of permanent GPS stations, operating for geodetic purposes, offers a tool for a dense and reliable remote sensing of atmospheric water vapor. Here the tropospheric delay observed on some continuous GPS (CGPS) stations of the Italian GPS network (RING) is analyzed and its time evolution is discussed. We focus mainly on the study of the wet component of the atmospheric delay of the GPS signals and the computation of the precipitable water by using co-located GPS and meteorological stations. The results are described and discussed in comparison with different meteorological observations collected during extreme weather conditions impacting the Campania region.

    The L'Aquila trial (2015)
    Geological Society, London
    Details
    Publication Date: 2019-02-25
    Description: The first stage of the trial in L’Aquila (Italy) ended with a conviction of seven experts, convened by the head of Civil Protection on 31 March 2009, for multiple manslaughter and serious injuries. They were sentenced to six years in jail, perpetual interdiction from public office and a fine of several million euros to be paid to the victims of the earthquake of 6 April 2009 (moment magnitude 6.3) for having caused, by their negligent conduct, the death of 29 persons and the injury of several others. The verdict had a tremendous impact on the scientific community and on the way scientists deliver their expert opinions to decision makers and society. This paper analyses the scientific argumentations reported in the Verdict Motivations, where scientific data and results were largely debated and misused to demonstrate that they should have been considered a tool to predict an impending large earthquake. Moreover, we show that the supposed message of reassurance was not generated at the experts’ meeting or by the official Istituto Nazionale di Geofisica e Vulcanologia reports. The media had a key role in conveying information during the seismic swarm, contributing to the risk perception. We stress that prevention actions based on seismic hazard knowledge are the best defence against earthquakes.

    Earthquake ethics through scientific knowledge, historical memory and societal awareness: the experience of direct internet information (2015)
    Geological Society
    Details
    Publication Date: 2020-02-25
    Description: The collection of web data on the effects of earthquakes and the diffusion of this information to the public receive growing interest from Italian citizens. Since 2007, more than 650 000 intensity questionnaires, describing more than 7800 earthquakes were collected. Two-way information exchange is important. Everybody records the local observed effects of earthquakes and then a global view can be obtained through the maps of the earthquakes that are generated in real-time. More than 23 000 permanent subscribers distributed throughout Italy are alerted in case of an earthquake, which reinforces participation. People are informed through e-mail, about events occurring in their area. The ‘alert’ service is a reminder that earthquakes are continuously present, but high magnitude events rarely occur. Every person knows what an earthquake is and this brings fear and the idea of death and destruction. Often there is also a belief that earthquakes are very rare occurrences. This fact feeds refusal and repression. A strong earthquake immediately changes surprised feelings into shock and desperation. A positive approach should comprise the following: (1) a better knowledge of seismicity, (2) constant awareness of seismic activity, (3) an understanding of the meaning of the probability applied to seismicity and (4) a movement towards positive activities such as building reinforcements and earthquake simulation activities. Social and ethical implications need to find an equilibrium point between alarmism and the undervaluation of the hazard.

    Details
    Publication Date: 2020-02-24
    Description: Geoethics reflects the intersection of geology, sociology and philosophy and frequently focuses on important environmental issues and problems often related to natural risk management and mitigation. Geoethics promotes a critical analysis of the use of natural resources, highlighting educational and communication aspects in sciences. Above all, Geoethics encourages geoscientists to assume responsibility in carrying out their research activities with the greatest integrity, especially since such activities can effectively contribute in guiding civil society and industry towards adopting sustainable practices in relation to the Geosphere. The research in Geoethics is multidisciplinary in nature, often requiring a team of experts of different backgrounds.

    Geoscientific Communication Problem with Communities for Disaster Prevention and Land Planning in Peru (2015)
    Springer
    Details
    Publication Date: 2020-02-24
    Description: The communication process between the geoscientists and native communities in risk areas can significantly affect disaster prevention and land use planning. In Peru, the problem of disaster prevention is a fundamental policy due to unfamiliarity and deficiency of the associate information on the population. It is possible that talk of disaster prevention it will be an unlikely ideal in a country where most towns have settled on unplanned projects by the constant change and the lack of interest from the authorities in such topics. However, it is anachronistic that the rural communities and towns continue to live without a plan to enable them to improve their quality of life. The correct use of geoscience information in the mass media can help in this work. The characteristics of the enterprise in Peru require more training by professionals in the geosciences and support communication specialists. In this paper, we analyze the problem of communication for disaster prevention in Peru, with the aim of contributing to the articulation of a disaster prevention strategy.

    Self-similar clustering distribution of structural features on Ascraeus Mons (Mars): implications for magma chamber depth (2015)
    Geological Society, London, Special Publications | Geological Society Publishing House

    Publication Date: 2021-11-08
    Description: In: Platz, T., Massironi, M., Byrne, P. K. & Hiesinger, H. (eds) 2015. Volcanism and Tectonism Across the Inner Solar System. Geological Society, London, Special Publications, 401, 203–218.
    Description: The occurrence and distribution of monogenic eruptive features in volcanic areas testify to the presence of deep-crustal or subcrustal magma reservoirs hydraulically connected to the surface via a fracture network. The spatial distribution of vents can be studied in terms of self-similar (fractal) clustering, described by a fractal exponent D and defined over a range of lengths (l) between a lower and upper cutoff, Lco and Uco, respectively. The computed Uco values for several volcanic fields on Earth match the thickness of the crust between vents and magma reservoirs at depth. This analysis can thus be extended to other volcanic fields and volcanoes on rocky planets in the solar system where features such as vents and dykes occur, and for where complementary geophysical data are currently lacking. We applied this method to the Ascraeus Mons volcano on Mars, which presents hundreds of collapse pits similar to those observed on Earth volcanoes that are most likely related to feeder dykes. Based on structural mapping with High Resolution Stereo Camera data at 12 m/px and Context Camera data at 6 m/px mosaics, more than 2300 collapse pits and dyke traces were analysed, revealing two distinct fractal clustered populations. The obtained Uco values reveal the presence and likely depth of both a deep magma reservoir (c. 60 km deep) and a small shallower chamber (c. 11 km deep). This analysis can help to better constrain the depth and time evolution of volcanic processes on Tharsis, and on terrestrial planets’ volcanoes in general.

    The clonal dependence of turion formation in the duckweed Spirodela polyrhiza - an ecogeographical approach (2014)
    In:  Physiologia Plantarum
    Details
    Publication Date: 2020-02-12
    Description: Formation of turions, the vegetative perennation organs, plays an important role in the survival strategy of Spirodela polyrhiza (L.) Schleiden. Turion formation [quantified as number of turions formed per frond; specific turion yield (SY)] was investigated in 27 clones collected from a wide geographical range. The Pearson correlation was tested with (1) duration of growing season (monthly average temperature of ≥10°C), (2) relative growth rate of the fronds, (3) longitude and latitude, and (4) several climatic parameters, in all possible single and multiple regressions. All single coefficients of determination were below 0.10. The highest correlation (R2 = 0.61; adjusted for the number of explaining variables 0.54) was found in a multiple linear regression with the following five parameters: average temperatures over the year and during the growing season, duration of the growing season and precipitation over the year and during the growth period. All these parameters were shown to have significant contributions. This equation was used successfully to predict the SY of five newly isolated clones. Finally, on the basis of all 32 clones the following conclusions were drawn: The mean annual temperature has the highest impact. It is suggested that lower temperatures decrease the survival rate of turions and that adaptation refers to increasing SY. The different levels of SY in the clones (ranging from SY = 0.22 to 5.9) were detected even after several years of in vitro cultivation. It is therefore assumed that these adaptations to the climatic conditions are genetically determined.

    Real-time clock offset prediction with an improved model (2014)
    In:  GPS Solutions
    Details
    Publication Date: 2020-02-12
    Description: The GPS orbit precision of the IGS ultra-rapid predicted (IGU-P) products has been remarkably improved since 2007. However, the satellite clock offsets of the IGU-P products have not shown sufficient high-quality prediction to achieve sub-decimeter precision in real-time precise point positioning (RTPPP), being at the level of 1–3 ns (30–90 cm) RMS in recent years. An improved prediction model for satellite clocks is proposed in order to enhance the precision of predicted clock offsets. First, the proposed prediction model adds a few cyclic terms to absorb the periodic effects, and a time adaptive function is used to adjust the weight of the observation in the prediction model. Second, initial deviations of the predictions are reduced by using a recomputed constant term. The simulation results have shown that the proposed prediction model can give a better performance than the IGU-P clock products and can achieve precision better than 0.55 ns (16.5 cm) in real-time predictions. In addition, the RTPPP method was chosen to test the efficiency of the new model for real-time static and kinematic positioning. The numerical examples using the data set of 140 IGS stations show that the static RTPPP precision based on the proposed clock model has been improved about 22.8 and 41.5 % in the east and height components compared to the IGU-P clock products, while the precisions in the north components are the equal. The kinematic example using three IGS stations shows that the kinematic RTPPP precision based on the proposed clock model has improved about 30, 72 and 44 % in the east, north and height components.

    Simulation of Multitemporal and Hyperspectral Vegetation Canopy Bidirectional Reflectance Using Detailed Virtual 3-D Canopy Models (2014)
    In:  IEEE Transactions on Geoscience and Remote Sensing
    Details
    Publication Date: 2020-02-12
    Description: The influence of plant and canopy architecture on canopy bidirectional reflectance and the bidirectional reflectance distribution function (BRDF) is the subject of this paper. To understand BRDF-influenced reflectance signals, this influence must be identified and quantified, which requires detailed knowledge concerning the structure and BRDF of the observed canopies. In situ BRDF measurements of canopies are time consuming and depend on the availability of a field goniometer. In contrast to field measurements, computer-based simulations of the canopy BRDF offer an alternative approach that considers parameter-driven setups of virtual canopies under constant illumination conditions. This paper presents the hyperspectral simulation of canopy reflectance (HySimCaR) system, which has been developed in the context of the EnMAP mission. This spectral, spatial, and temporal simulation system consists of detailed virtual 3-D cereal canopies of different phenological stages, whose geometries are linked to the corresponding spectral information. The system enables the simulation of realistic bidirectional reflectance spectra on the basis of virtual 3-D scenarios by incorporating any possible viewing position with ray- tracing techniques. The parameterization of a number of canopy structure parameters, such as phe nological stage, row distance, and row orientation, enables the modeling of the bidirectional reflectance and, based on them, the approximation of the BRDF for many structurally different cereal canopies. HySimCaR has been validated with respect to structural and spectral accuracy using three cereal types, namely, wheat, rye, and barley, at 13 different phenological stages. The results show that the virtual cereal canopies are re-created in a realistic way, and it is possible to model their detailed canopy bidirectional reflectance and their BRDF using HySimCaR.

    Red Mediterranean Soils in Jordan: New insights in their origin, genesis, and role as environmental archives (2014)
    In:  Catena
    Details
    Publication Date: 2020-02-12
    Description: It is disputed whether Terrae Rossae form mainly out of the bedrock residue, from allochthonous material like aerosols, or by isovolumetric replacement. Furthermore, whether they are mainly relic soils or are still forming is subject to debate. These questions were addressed by comparing the geochemistry of several limestone and basalt based Red Mediterranean Soils with Lithosols on sandstone and limestone in Jordan. The bedrock residue was included at all test sites. Paleosols and initial soils on the limestone Regolith of historic ruins delivered insights into the possible time frame of soil development. A major reduction of elements in the soils compared to bedrock could be observed for CaO in carbonaceous, SiO2 in arenaceous, and Fe2O3 and MgO in basaltic rocks. All Terrae Rossae, however, are characterised by a significant increase of SiO2, Al2O3, TiO2, Fe2O3, K2O, and a range of mainly metallic minor elements that cannot be derived from the bedrock. A reasonable explanation could be input via aeolian transfer of minerals, with clay minerals as the major carrier plus quartz. This input probably originates in Egypt and Sudan and has remained largely unchanged over long periods. Growing aridity during the Holocene has apparently increased the share of silt while clay deposition and soil development has been reduced. At some sites, metasomatic processes have contributed to soil development and might help to explain the depth of some profiles. However, formation of red soils during the Holocene seems very limited, and the Red Mediterranean Soils may represent remains of a paleolandscape.

    Discordance between cosmogenic nuclide concentrations in amalgamated sands and individual fluvial pebbles in an arid zone catchment (2014)
    In:  Quaternary Geochronology
    Details
    Publication Date: 2024-05-06
    Description: Based on cosmogenic 10Be and 26Al analyses in 15 individual detrital quartz pebbles (16e21 mm) and cosmogenic 10Be in amalgamated medium sand (0.25e0.50 mm), all collected from the outlet of the upper Gaub River catchment in Namibia, quartz pebbles yield a substantially lower average denudation rate than those yielded by the amalgamated sand sample. 10Be and 26Al concentrations in the 15 indi- Accepted 9 April 2012 Available online xxx vidual pebbles span nearly two orders of magnitude (0.22 ± 0.01 to 20.74 ± 0.52 x 10 6 10 Be atoms g-1 and 1.35 ± 0.09 to 72.76 ± 2.04 x 106 26Al atoms g-1, respectively) and yield average denudation rates of w0.7 m Myr-1 (10Be) and w0.9 m Myr-1 (26Al). In contrast, the amalgamated sand yields an average Keywords: Beryllium-10 10Be concentration of 0.77 ± 0.03 x 106 atoms g-1, and an associated mean denudation rate of Aluminium-26 Neon-21 Cosmogenic nuclide Grain size bias Namibia 9.6 ± 1.1 m Myr-1, an order of magnitude greater than the rates obtained for the amalgamated pebbles. The inconsistency between the 10Be and 26Al in the pebbles and the 10Be in the amalgamated sand is likely due to the combined effect of differential sediment sourcing and longer sediment transport times for the pebbles compared to the sand-sized grains. The amalgamated sands leaving the catchment are an aggregate of grains originating from all quartz-bearing rocks in all parts of the catchment. Thus, the cosmogenic nuclide inventories of these sands record the overall average lowering rate of the landscape. The pebbles originate from quartz vein outcrops throughout the catchment, and the episodic erosion of the latter means that the pebbles will have higher nuclide inventories than the surrounding bedrock and soil, and therefore also higher than the amalgamated sand grains. The order-of-magnitude grain size bias observed in the Gaub has important implications for using cosmogenic nuclide abundances in deposi- tional surfaces because in arid environments, akin to our study catchment, pebble-sized clasts yield substantially underestimated palaeo-denudation rates. Our results highlight the importance of carefully considering geomorphology and grain size when interpreting cosmogenic nuclide data in depositional surfaces.

    Modeling the 2004 Sumatra tsunami at Seychelles Islands: site-effect analysis and comparison with observations (2014)
    Springer Netherlands | Springer Science+Business Media B.V.
    Details
    Publication Date: 2017-04-04
    Description: The Mw = 9.1 mega-thrust Sumatra–Andaman earthquake that occurred on December 26, 2004, was followed by a devastating tsunami that killed hundreds of thousands of people and caused catastrophic effects on human settlements and environments along many coasts of the Indian Ocean, where even countries very far from the source were affected. One of these cases is represented by the Republic of Seychelles, where the tsunami reached the region about 7 h after the earthquake and produced relevant damages, despite the country was more than 4,500 km far from the seismic source. In the present work, we present and discuss a study of the 2004 Sumatra tsunami by means of numerical simulations with the attention focused on the effects observed at the Seychelles Archipelago, a region never previously investigated with this approach. The case is interesting since these islands lay on a very shallow oceanic platform with steep slopes so as the ocean depth changes from thousands to few tens of meters over short distances, with significant effects on the tsunami propagation features: the waves are strongly refracted by the oceanic platform and the tsunami signal is modified by the introduction of additional frequencies. The study is used also to validate the UBO-TSUFD numerical code on a real tsunami event in the far field, and the results are compared with the available observations, i.e., the sea level time series recorded at the Pointe La Rue station, Mahe ́ Island, and run-up measurements and inundation lines surveyed few weeks after the tsunami at Praslin Island, where the tsunami hit during low tide. Synthetic results are found in good agreement with observations, even though some of the observations remain not fully solved. Moreover, simulations have been run in high-tide condition since the 2004 Sumatra tsunami hitting at high tide can be taken as the worst-case scenario for the Seychelles islands and used for tsunami hazard and risk assessments

    The UBO-TSUFD tsunami inundation model: validation and application to a tsunami case study focused on the city of Catania, Italy (2014)
    Details
    Publication Date: 2020-02-24
    Description: Nowadays numerical models are a powerful tool in tsunami research since they can be used (i) to reconstruct modern and historical events, (ii) to cast new light on tsunami sources by inverting tsunami data and observations, (iii) to build scenarios in the frame of tsunami mitigation plans, and (iv) to produce forecasts of tsunami impact and inundation in systems of early warning. In parallel with the general recognition of the importance of numerical tsunami simulations, the demand has grown for reliable tsunami codes, validated through tests agreed upon by the tsunami community. This paper presents the tsunami code UBO-TSUFD that has been developed at the University of Bologna, Italy, and that solves the non-linear shallow water (NSW) equations in a Cartesian frame, with inclusion of bottom friction and exclusion of the Coriolis force, by means of a leapfrog (LF) finite-difference scheme on a staggered grid and that accounts for moving boundaries to compute sea inundation and withdrawal at the coast. Results of UBO-TSUFD applied to four classical benchmark problems are shown: two benchmarks are based on analytical solutions, one on a plane wave propagating on a flat channel with a constant slope beach; and one on a laboratory experiment. The code is proven to perform very satisfactorily since it reproduces quite well the benchmark theoretical and experimental data. Further, the code is applied to a realistic tsunami case: a scenario of a tsunami threatening the coasts of eastern Sicily, Italy, is defined and discussed based on the historical tsunami of 11 January 1693, i.e. one of the most severe events in the Italian history.

    Compositionally zoned crystals and real-time degassing data reveal changes in magma transfer dynamics during the 2006 summit eruptive episodes of Mt. Etna (2014)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-01-27
    Description: One of the major objectives of volcanology remains relating variations in surface monitoring signals to the magmatic processes at depth that cause these variations. We present a method that enables compositional and temporal information stored in zoning of minerals (olivine in this case) to be linked to observations of real-time degassing data. The integrated record may reveal details of the dynamics of gradual evolution of a plumbing system during eruption. We illustrate our approach using the 2006 summit eruptive episodes of Mt. Etna. We find that the history tracked by olivine crystals, and hence, most likely the magma pathways within the shallow plumbing system of Mt. Etna, differed considerably between the July and October eruptions. The compositional and temporal record preserved in the olivine zoning patterns reveal two mafic recharge events within months of each other (June and September 2006), and each of these magma supplies may have triggered the initiation of different eruptive cycles (July 14–24 and August 31–December 14). Correlation of these observations with gas monitoring data shows that the systematic rise of the CO2/SO2gas values is associated with the gradual (preand syn-eruptive) supply of batches of gas-rich mafic magma into segments of Etna’s shallow plumbing system, where mixing with pre-existing and more evolved magma occurred.

    Description: We present a new interface between the geochemical simulator PHREEQC and the open source language R. It represents a tool to flexibly and efficiently program and automate every aspect of geochemical modelling. The interface helps particularly to setup and run large numbers of simulations and visualise the results. Also profiting of numberless high-quality R extension packages, performing sensitivity analysis or Monte Carlo simulations becomes straightforward. Further, an algorithm to speedup reactive transport simulations starting from homogeneous or zone- homogeneous state is programmed and successfully evaluated through the interface. It proved effective and could therefore be included in any reactive transport simulator.

    Hydrochemical water evolution in the Aral Sea Basin Part II: Confined groundwater of the Amu Darya Delta – evolution from the headwaters to the delta and SiO2 geothermometry (2013)
    In:  Journal of Hydrology
    Details
    Publication Date: 2020-02-12
    Description: We studied 40 artesian wells (AWs) in the Amu Darya Delta. These wells include high-salinity (∼ 52 g/l) and saline (5 – 24 g/l) waters but are mostly low-salinity waters (1.3 – 2.9 g/l). The low-salinity AWs cluster into three types, reflecting the variable mixing of different end-member solutes: (residual) brines and solutes deriving from silicate alteration, dissolution of limestone and dissolution of gypsum. The solutes are all undersaturated in calcite and gypsum, contain a substantial cation excess against dissolved inorganic carbon and are characterised by low Ca/SO4 ratios. On the basis of the hydrochemical mass budgets of model cases, we demonstrate that Na-rich Cl-brines (45-48%) and a Na2SO4-brine (30-47%) are the dominant solute components. The solutes derived from aluminium silicate alteration are minor components (7.3 – 19.4%). Even less important are solutes from limestone or gypsum dissolution (0.05 – 3.7%). These waters are unlikely to have originated from sediments hosting gypsum. The low-salinity AWs must have acquired their dominant hydrochemical signatures under non-equilibrium conditions between their remote (unknown) seepage areas and their discharge locations. This acquisition may have begun during the early hydrochemical groundwater evolution when meteoric or surface water passed the critical zone under an arid climate regime. Warmer saline AWs (∼40°C) hosted in deeper Cretaceous formations contain a high portion of NaCl-rich brine (85%) and some are saturated in gypsum. These waters were derived from fluids rising along faults from pre-Cretaceous strata. The high-salinity and relatively cold AWs discharge close to the retreating Aral Sea south of its western basin. These AWs are suboxic, and Si concentrations are very low. The AW hydrochemical signatures reflect the dissolution of halite and gypsum. We observed positive correlations between temperature, Br, B and Si. The temperature correlation with bromide likely documents the transformation of organically bound Br. The silica concentrations in low-salinity AWs southeast of the Aral Sea (eastern basin) are close to quartz saturation and define a chemical Si-geothermometer.

    Salt diapirism driven by differential loading - Some insights from analogue modelling (2013)
    In:  Tectonophysics
    Details
    Publication Date: 2020-02-12
    Description: We applied scaled physical analogue experiments to investigate the early development of salt diapirs induced by differential sedimentary loading in an intra-continental basin realm (e.g. the North German Basin). During the experiments, deformation in a salt-analogue viscous layer was initiated by variations in the thickness of an overlying brittle material and subsequent accumulation of the brittle material further sustained deformation. A 2D optical image correlation system was used to monitor the strain evolution in the salt analogue material. Our models indicate that the formation of salt pillow structures can be achieved by minimum variations in the overburden loading. The increase of differential loading by adding synkinematic layers in the subsided areas causes not only an active piercing of the viscous layer through the brittle overburden but also an additional uplift in the adjacent areas. These elevations, named “secondary structures”, act as origins for a successive generation of diapirs. Consequently, an initial perturbation of the salt–sediment-interface can lead to a lateral propagation temporally shifted diapirs. The linkage between primary and secondary structures is reflected in the synkinematic overburden layers such as overlapping peripheral sinks in the transition zone between two diapirs. These sinks, in turn, are a frequently observable phenomenon around salt structures of the North German basin indicating that “secondary diapirism” is an underestimated process – besides regional tectonic stresses – influencing the evolution of salt structures.

    Source modelling of the M5-6 Emilia-Romagna, Italy, earthquakes (May 20-29, 2012). (2013)
    In:  Geophysical Journal International
    Details
    Publication Date: 2020-02-12
    Description: On 2012 May 20 and 29, two damaging earthquakes with magnitudes Mw 6.1 and 5.9, respectively, struck the Emilia-Romagna region in the sedimentary Po Plain, Northern Italy, causing 26 fatalities, significant damage to historical buildings and substantial impact to the economy of the region. The earthquake sequence included four more aftershocks with Mw ≥ 5.0, all at shallow depths (about 7–9 km), with similar WNW–ESE striking reverse mechanism. The timeline of the sequence suggests significant static stress interaction between the largest events. We perform here a detailed source inversion, first adopting a point source approximation and considering pure double couple and full moment tensor source models. We compare different extended source inversion approaches for the two largest events, and find that the rupture occurred in both cases along a subhorizontal plane, dipping towards SSW. Directivity is well detected for the May 20 main shock, indicating that the rupture propagated unilaterally towards SE. Based on the focal mechanism solution, we further estimate the co-seismic static stress change induced by the May 20 event. By using the rate-and-state model and a Poissonian earthquake occurrence, we infer that the second largest event of May 29 was induced with a probability in the range 0.2–0.4. This suggests that the segment of fault was already prone to rupture. Finally, we estimate peak ground accelerations for the two main events as occurred separately or simultaneously. For the scenario involving hypothetical rupture areas of both main events, we estimate Mw = 6.3 and an increase of ground acceleration by 50 per cent. The approach we propose may help to quantify rapidly which regions are invested by a significant increase of the hazard, bearing the potential for large aftershocks or even a second main shock.

    Antarctic ice-mass balance 2002 to 2011: regional re-analysis of GRACE satellite gravimetry measurements with improved estimate of glacial-isostatic adjustment (2013)
    In:  The Cryosphere
    Details
    Publication Date: 2020-02-12
    Description: We present regional-scale mass balances for 25 drainage basins of the Antarctic Ice Sheet (AIS) from satellite observations of the Gravity and Climate Experiment (GRACE) for the years 2002–2011. Satellite gravimetry estimates of the AIS mass balance are strongly influenced by mass movement in the Earth interior caused by ice advance and retreat during the last glacial cycle. Here, we develop an improved glacial-isostatic adjustment (GIA) estimate for Antarctica using newly available GPS uplift rates, allowing us to more accurately separate GIA-induced trends in the GRACE gravity fields from those caused by current imbalances of the AIS. Our revised GIA estimate is considerably lower than previous predictions, yielding an (upper) estimate of apparent mass change of 48 ± 18 Gt yr−1. Therefore, our AIS mass balance of −103 ± 23 Gt yr−1 is considerably less negative than previous GRACE estimates. The Northern Antarctic Peninsula and the Amundsen Sea Sector exhibit the largest mass loss (−25 ± 6 Gt yr−1 and −126 ± 11 Gt yr−1, respectively). In contrast, East Antarctica exhibits a slightly positive mass balance (19 ± 16 Gt yr−1), which is, however, mostly the consequence of compensating mass anomalies in Dronning Maud and Enderby Land (positive) and Wilkes and George V Land (negative) due to interannual accumulation variations. In total, 7% of the area constitute more than half of the AIS imbalance (53%), contributing −151 ± 9 Gt yr−1 to global mean sea-level change. Most of this imbalance is caused by long-term ice-dynamic speed up expected to prevail in the future.

    Anomalous subglacial heat flow in central Greenland induced by the Iceland plume (2013)
    In:  Geophysical Research Abstracts, Vol. 15, EGU2013-10918
    Details
    Publication Date: 2020-02-12
    Description: 3000 m of ice sheet thickness has ensured that central Greenland has kept it geothermal heat flow (GHF) distribution enigmatic. Some few direct ice temperature measurements from deep ice cores reveal a GHF of 50 to 60 mW/m2 in the Summit region and this is noticeably above what would be expected for the underlying Early Proterozoic lithosphere. In addition, indirect estimates from zones of rapid basal melting suggest extreme anomalies 15 to 30 times continental background. Subglacial topography indicates caldera like topographic features in the zones hinting at possible volcanic activity in the past [1], and all of these observations combined hint at an anomalous lithospheric structure. Further supporting this comes from new high-resolution P-wave tomography, which shows a strong thermal anomaly in the lithosphere crossing Greenland from east to west [2]. Rock outcrops at the eastern and western end of this zone indicate significant former magmatic activity, older in the east and younger in the west. Additionally, plate modelling studies suggest that the Greenland plate passed over the mantle plume that is currently under Iceland from late Cretaceous to Neogene times, consistent with the evidence from age of magmatism. Evidence of rapid basal melt revealed by ice penetrating radar along the hypocentre of the putative plume track indicates that it continues to affect the Greenland continental geotherm today. We analyse plume-induced thermal disturbance of the present-day lithosphere and their effects on the central Greenland ice sheet by using a novel evolutionary model of the climate-ice-lithosphere-upper mantle system. Our results indicate that mantle plume-induced erosion of the lithosphere has occurred, explaining caldera-type volcanic structures, the GHF anomaly, and requiring dyke intrusion into the crust during the early Cenozoic. The residual thermo-mechanical effect of the mantle plume has raised deep-sourced heat flow by over 25 mW/m2 since 60 Ma and explains the high basal melting rates of the Greenland ice sheet observed in the study area.

    The relationship of thermospheric density anomaly with electron temperature, small-scale FAC, and ion up-flow in the cusp region, as observed by CHAMP and DMSP satellites (2013)
    In:  Annales Geophysicae
    Details
    Publication Date: 2020-02-12
    Description: We present in a statistical study a comparison of thermospheric mass density enhancements (ρrel) with electron temperature (Te), small-scale field-aligned currents (SSFACs), and vertical ion velocity (Vz) at high latitudes around noon magnetic local time (MLT). Satellite data from CHAMP (CHAllenging Minisatellite Payload) and DMSP (Defense Meteorological Satellite Program) sampling the Northern Hemisphere during the years 2002–2005 are used. In a first step we investigate the distribution of the measured quantities in a magnetic latitude (MLat) versus MLT frame. All considered variables exhibit prominent peak amplitudes in the cusp region. A superposed epoch analysis was performed to examine causal relationship between the quantities. The occurrence of a thermospheric relative mass density anomaly, ρrel 〉1.2, in the cusp region is defining an event. The location of the density peak is taken as a reference latitude (Δ MLat = 0°). Interestingly, all the considered quantities, SSFACs, Te, and Vz are co-located with the density anomaly. The amplitudes of the peaks exhibit different characters of seasonal variation. The average relative density enhancement of the more prominent density peaks considered in this study amounts to 1.33 during all seasons. As expected, SSFACs are largest in summer with average amplitudes equal to 2.56 μA m−2, decaying to 2.00 μA m−2 in winter. The event related enhancements of Te and Vz are both largest in winter (Δ Te =730 K, Vz =136 m s−1) and smallest in summer (Δ Te = 377 K, Vz = 57 m s−1. Based on the similarity of the seasonal behaviour we suggest a close relationship between these two quantities. A correlation analysis supports a linear relation with a high coefficient greater than or equal to 0.93, irrespective of season. Our preferred explanation is that dayside reconnection fuels Joule heating of the thermosphere causing air upwelling and at the same time heating of the electron gas that pulls up ions along affected flux tubes.
