    Upper Mantle Anisotropy in Victoria Land (Antarctica) (1998)

    Notes: Abstract —During the Austral Summers 1993–94 and 1994–95, we operated two temporary seismic arrays in the Victoria Land region, Antarctica. The first was located around the Mt. Melbourne volcano, near Terra Nova Bay, and the second southward, along the ACRUP1 Geotraverse. The aim of these experiments was to provide additional constraints on the Moho geometry and on lithosphere-astheno sphere structure in this zone. For this reason, a number of techniques were applied to recorded teleseismic data. In this paper we describe the results of the analysis on SKS- and S-wave splitting, which show the presence of seismic anisotropy. Computed fast polarization directions range, on average, between 131° and 166°, and delay times are on the order of 1 s. We presume that anisotropy is mainly located in the upper mantle, although we cannot detect, at present, if a contribution from the crust does exist. The fast polarization direction we determine is quite parallel to the opening of the Ross Sea, an active rift system, but also to the Absolute Plate Motion direction. Therefore, we assume that the identified anisotropy may be induced by the extension, activated by plate motion and is still related to it.

    Seismic deformation in the Mediterranean area estimated by moment tensor summation (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 122 (1995), S. 0 
    Details
    ISSN: 1365-246X

    Topics: Geosciences
    Notes: Theoretical relationships allow the distributed deformation due to seismic activity to be quantified on the basis of the analysis of moment tensors. We apply this method to a data set consisting of seismic events that have occurred in the past 85 yr (1908–1992) along the most important seismogenic zones of the Mediterranean region. We use the Centroid Moment Tensor (CMT) Catalog prepared at Harvard University, covering the last 16 yr, and older data from Jackson & McKenzie (1988). We determine the seismic deformation and compare it to estimates of the overall deformation as obtained from global plate motion and geological studies. We generally find that the geometry of seismic deformation is similar to tectonic predictions. Even though spanning a shorter time interval, the CMT Catalog often gives a better estimate of deformation geometry than the whole data set (85 yr). Seismic deformation generally ranges from less than 10 per cent to more than 90 per cent of the total deformation. Uncertainties arise because data sets may not be representative of the long-term seismic behaviour of each zone. More reliable estimates for comparison with geodynamic processes should result from analysis of a longer time period, for which no instrumental data are available. The similarity of the deformation geometry using CMT data with tectonic expectations suggests, for several zones, the possibility of using historical data to infer longer term deformation rates based on current deformation geometry.

    The new Italian seismic hazard model (MPS19) (2021)
    In:  Annals of Geophysics
    Details
    Publication Date: 2022-05-25
    Description: We describe the main structure and outcomes of the new probabilistic seismic hazard model for Italy, MPS19 [Modello di Pericolosità Sismica, 2019]. Besides to outline the probabilistic framework adopted, the multitude of new data that have been made available after the preparation of the previous MPS04, and the set of earthquake rate and ground motion models used, we give particular emphasis to the main novelties of the modeling and the MPS19 outcomes. Specifically, we (i) introduce a novel approach to estimate and to visualize the epistemic uncertainty over the whole country; (ii) assign weights to each model components (earthquake rate and ground motion models) according to a quantitative testing phase and structured experts’ elicitation sessions; (iii) test (retrospectively) the MPS19 outcomes with the horizontal peak ground acceleration observed in the last decades, and the macroseismic intensities of the last centuries; (iv) introduce a pioneering approach to build MPS19_cluster, which accounts for the effect of earthquakes that have been removed by declustering. Finally, to make the interpretation of MPS19 outcomes easier for a wide range of possible stakeholders, we represent the final result also in terms of probability to exceed 0.15 g in 50 years.
