    Moment magnitude (Mw) from hydrophone records of low energy volcanic quakes (2023)
    Springer
    Details
    Publication Date: 2023-01-18
    Description: 〈jats:title〉Abstract〈/jats:title〉〈jats:p〉Earthquake magnitude calibration using hydrophone records has been carried out at Campi Flegrei caldera, an active area close to the highly populated area of Naples city, partly undersea. Definite integrals of the hydrophone records amplitude spectra, between the limits of 1 and 20 Hz, were calculated on a set of small volcano-tectonic earthquakes with moment magnitudes ranging from 1 to 3.3. The coefficients of a linear relationship between the logarithm of these integrals and the magnitude were obtained by linear optimization, thus defining a useful equation to calculate the moment magnitude from the hydrophone record spectra. This method could be easily exported to other volcanic areas, where submerged volcanoes are monitored by networks of hydrophones and seismic sensors on land. The proposed approach allows indeed magnitude measurements of small magnitude earthquakes occurring at sea, thus adding useful information to the seismicity of these volcanoes.〈/jats:p〉

    A Tool to Aid the Navigation in La Spezia Harbour (Italy) (2023)
    Springer
    Details
    Publication Date: 2023-01-18
    Description: The knowledge of sea level in harbours is very important to manage port activities (safety of navigation, prevention of ship stranding, optimization of vessel loading, water quality control). In this article we describe the use of a software tool developed to help local authorities and working organizations to optimize navigation and avoid or manage hazardous situations due to sea level changes in port basins. This prototype application, starting from reading data coming from a monitoring station in La Spezia harbour (in North Western Italy), updates dynamically the port bathymetry based on sea level oscillations (measured in the past or real-time, or expected in the near future). Then, it detects potentially dangerous areas for a given ship moving in the basin at a certain time, by means of the idea of “virtual traffic lights”: sea level variations are provided as parameters to the application that performs the updating of the bathymetric map and the subdivision of the harbour in allowed (green)/warning (yellow)/prohibited (red) areas for each ship, based on its draft. The tool can provide a useful support interface to competent authorities to avoid or manage critical situations by detecting hazardous areas for a given vessel at a given time.

    The 2020 European Seismic Hazard Model: Milestones and Lessons Learned (2023)
    Springer Nature
    Details
    Publication Date: 2023-01-18
    Description: The 2020 update of the European Seismic Hazard Model (ESHM20) is the most recent seismic hazard model of the Euro-Mediterranean region. It was built upon unified and homogenized datasets including earthquake catalogues, active faults, ground motion recordings and state-of-the-art modelling components, i.e. earthquake rates forecast and regionally variable ground motion characteristic models. ESHM20 replaces the 2013 European Seismic Hazard Model (ESHM13), and it is the first regional model to provide two informative hazard maps for the next update of the European Seismic Design Code (CEN EC8). ESHM20 is also one of the key components of the first publicly available seismic risk model for Europe. This chapter provides a short summary of ESHM20 by highlighting its main features and describing some lessons learned during the model’s development.

    Combining earth sciences with archaeology to investigate natural risks related to the cultural heritage of the Marsica region (central Apennines, Italy) (2023)
    Springer
    Details
    Publication Date: 2023-01-19
    Description: Methods of Earth Sciences have been employed in archaeological sites of the Marsica region, central Italy, in two different perspectives: to enhance knowledge on past natural events which damaged/destroyed ancient settlements/monuments and to gather data useful/necessary for preservation of the local cultural heritage. Within this wide perspective, the paper deals with (i) recent archaeoseismological investigations at Alba Fucens and other sites of the Fucino Plain which add evidence of sudden building collapse to the already available (archaeoseismological and paleoseismological) data concerning seismicity of fifth-sixth century AD; (ii) archaeological investigations on remains of the Medieval church of San Bartolomeo showing that coseismic damage in 1349 caused the abandonment of part of the building and its (re)use for burials; (iii) evidence of slope instability which caused rapid mass deposition in the lowest sector of ancient Alba Fucens since around the half of the sixth century AD, inhibiting the occupation of the Roman town; (iv) capable faulting potentially affecting the westernmost sector of the huge hydraulic works made by Romans during the first-second century AD to drain former Lake Fucino.

    Sensitivity analysis of polar orbiter motion to lunar viscoelastic tidal deformation (2023)
    Springer
    Details
    Publication Date: 2023-03-30
    Description: We investigate the impact of viscoelastic tidal deformation of the Moon on the motion of a polar orbiter. The dissipative effects in the Moon’s interior, i.e., tidal phase lags, are modeled as Fourier series sampled at given frequencies associated with linear combinations of Delaunay arguments, the fundamental parameters describing the lunar motion around the Earth and the Sun. We implement the tidal model to evaluate the temporal lunar gravity field and the induced perturbation on the orbiter. We validate the numerical scheme via a frequency analysis of the perturbed orbital motion. We show that, in the case of the Lunar Reconnaissance Orbiter at a low altitude of less than 200 km, the main lunar tides and hence the potential Love numbers around the monthly and some multiple frequencies are dynamically separable. The omission of those effects in practice introduces a position error at the level of a few decimeters within 10 days.

    The peperino rocks: historical and volcanological overview (2023)
    Springer
    Details
    Publication Date: 2023-03-31
    Description: The name peperino derives from the Italian word pepe (pepper) and has been used in the common language for lithified volcanic deposits characterized by grey to dark grey color and granular texture, resembling that of ground pepper. Among these, the best-known examples are represented by some phreatomagmatic deposits of the Colli Albani Volcanic District, near Rome, and ignimbrite deposits of the Cimini Mountains near Viterbo (Northern Latium), which have been widely employed in artifacts of historical and archaeological interest. In particular, these resistant volcanic rocks have been widely employed by the Etruscans and Romans since the 7 th century BCE to produce sarcophagi and dimension stones, as well as architectural and ornamental elements in central Italy up to the present.

    Evaluation of Surface Layer Stability Functions and Their Extension to First Order Turbulent Closures for Weakly and Strongly Stratified Stable Boundary Layer (2023)
    Springer Nature
    In:  EPIC3Boundary-Layer Meteorology, Springer Nature, ISSN: 0006-8314
    Details
    Publication Date: 2023-04-25
    Description: In this study, we utilize a generalization of Monin–Obukhov similarity theory to construct first order turbulent closures for single-column models of the atmospheric boundary layer (ABL). A set of widely used universal functions for dimensionless gradients is evaluated. Two test cases based on Large-Eddy Simulations (LES) experimental setups are considered – weakly stable ABL (GABLS1; Beare et al. in Bound Layer Meteorol 118(2):247–272,2006), and very strongly stratified ABL (van der Linden et al. in Bound Layer Meteorol 173(2):165–192, 2019). The comparison shows that approximations obtained using a linear dimensionless velocity gradient tend to match the LES data more closely. In particular, the EFB (Energy- and Flux- Budget) closure proposed by Zilitinkevich et al. (Bound Layer Meteorol 146(3):341–373, 2013) has the best performance for the tests considered here. We also test surface layer “bulk formulas” based on these universal functions. The same LES data are utilized for comparison. The setup showcases the behavior of surface scheme, when one assumes that the velocity and temperature profiles in ABL are represented correctly. The advantages and disadvantages of different surface schemes are revealed.

    Crystal orientation fabric anisotropy causes directional hardening of the Northeast Greenland Ice Stream (2023)
    Springer Nature
    In:  EPIC3Nature Communications, Springer Nature, 14(1), pp. 2653-2653, ISSN: 2041-1723
    Details
    Publication Date: 2023-10-19
    Description: The dynamic mass loss of ice sheets constitutes one of the biggest uncertainties in projections of ice-sheet evolution. One central, understudied aspect of ice flow is how the bulk orientation of the crystal orientation fabric translates to the mechanical anisotropy of ice. Here we show the spatial distribution of the depth-averaged horizontal anisotropy and corresponding directional flow-enhancement factors covering a large area of the Northeast Greenland Ice Stream onset. Our results are based on airborne and ground-based radar surveys, ice-core observations, and numerical ice-flow modelling. They show a strong spatial variability of the horizontal anisotropy and a rapid crystal reorganisation on the order of hundreds of years coinciding with the ice-stream geometry. Compared to isotropic ice, parts of the ice stream are found to be more than one order of magnitude harder for along-flow extension/compression while the shear margins are potentially softened by a factor of two for horizontal-shear deformation.

    Principles for transformative ocean governance (2023)
    Springer Nature
    In:  EPIC3Nature Sustainability, Springer Nature, pp. 1-13, ISSN: 2398-9629
    Details
    Publication Date: 2023-10-30
    Description: With a focus on oceans, we collaborated across ecological, social and legal disciplines to respond to the United Nations call for transformation in the ‘2030 Agenda for Sustainable Development’. We developed a set of 13 principles that strategically and critically connect transformative ocean research to transformative ocean governance (complementing the UN Decade for Ocean Science). We used a rigorous, iterative and transparent consensus-building approach to define the principles, which can interact in supporting, neutral or sometimes conflicting ways. We recommend that the principles could be applied as a comprehensive set and discuss how to learn from their interactions, particularly those that reveal hidden tensions. The principles can bring and keep together partnerships for innovative ocean action. This action must respond to the many calls to reform current ocean-use practices which are based on economic growth models that have perpetuated inequities and fuelled conflict and environmental decline.
