    Comparison of the historic seismicity and strain-rate pattern from a dense GPS-GNSS network solution in the Italian Peninsula (2018)
    Elsevier B.V. on behalf of KeAi Communications Co., Ltd

    Publication Date: 2018-03-01
    Description: Geodesy, Geodynamics and Tectonics of the Italian Peninsula
    Description: We present a dense crustal velocity field and corresponding strain-rate pattern computed using Global Positioning System (GPS)- Global Navigation Satellite System (GNSS) data from several hundred permanent stations in the Italian Peninsula. GPS data analysis is based on the GAMIT/GLOBK 10.6 software, which was developed and maintained mainly by Massachusetts Institute of Technology (MIT), using tools based on the distributed-sessions approach implemented in this package. The GPS data span the period from January 2008 to December 2012 and come from several different permanent GPS networks in Italy. The GLOBK package implemented in the last version of the GAMIT package is used to compute the position time-series and velocities registered in the International Terrestrial Reference Frame (ITRF) 2008. The resulting high-density intra-plate velocity field provides indications of the tectonics of the Mediterranean region. A computation of the strain-rate pattern from GPS data is performed and compared with the map of the epicentral locations of historical earthquakes that occurred in the last 1000 years in the Italian territory, showing that, in general, higher crustal deformation rates are active in regions affected by seismicity of greater magnitude.

    Geodynamics of the Calabrian Arc area (Italy) inferred from a dense GNSS network observations (2018)
    Elsevier B.V. on behalf of KeAi Communications Co., Ltd
    Details
    Publication Date: 2018-03-01
    Description: Geodynamics of the Calabrian Arc, Geodesy, Tectonics, Strain Rate.
    Description: The tectonics and geodynamics of the Calabria region are presented in this study. These are inferred by precise computation of Global Navigation Satellite Systems (GNSS) permanent station velocities in a stable Eurasian reference framework. This allowed computation of the coordinates, variance and covariance matrixes, and horizontal and vertical velocities of the 36 permanent sites analyzed, together with the strain rates, and using different techniques. Interesting geodynamic phenomena are presented, including compressional, and deformational fields in the Tyrrhenian coastal sites of Calabria, extensional trends of the Ionian coastal sites, and sliding movement of the Crotone Basin. Conversely, on the northern Tyrrhenian side of the network near the Cilento Park area, the usual extensional tectonic perpendicular to the Apennine chain is observed. The largescale pattern of the GNSS height velocities is shown, which is characterized by general interesting geodynamic vertical effects that appear to be due to geophysical movement and anthropic activity. Finally, the strain-rate fields computed through three different techniques are compared.

    Integrated ultrasonic, laser scanning and petrographical characterisation of carbonate building materials on an architectural structure of a historic building (2018)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2018-03-01
    Description: Several non-destructive (ND) techniques are presented as a tool for the evaluation of the conservation state of carbonate building materials of the “Palazzo di Città”, a historic building in the centre of Cagliari, a town in Italy. In this study, considering both the nature of the building materials and the constructive types of the investigated architectural structure, ultrasonic investigations were carried at 54 kHz. The ultrasonic measurements were performed both in the laboratory and in situ using the portable ultrasonic non-destructive digital indicating tester (PUNDIT Lab plus©) by Proceq (Schwerzenbach, Switzerland). The ultrasonic measurements were integrated by a petrographical and petrophysical study of the investigated stone materials in order to correlate their petrographical-petrophysical features with the elastic ones. A further implementation was carried out comparing elasto-mechanical and petrographical-petrophysical features of the investigated carbonate materials with surface geometric anomalies computed by means of the architectonic terrestrial laser scanner (TLS) application. In particular, we used a Leica HDS-6200 TLS to study the complex shape of some artifacts from the “Palazzo di Città” monumental compound. A multi station approach was adopted in order to acquire more than 180 million points by performing 30 high resolution structured scans. After TLS data elaboration with JRC 3D Reconstructor® software, the 3D model of the buildings together with morphological anomalies of some artifacts were computed in order to highlight the zones where the deformation was more evident.
