    Late Quaternary deformation of the southern Adriatic foreland (southern Apulia) from mesostructural data: preliminary results (2008)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: Southern Apulia (Adriatic foreland, Italy), has long been considered a “stable area” lying in between two active orogens, but in fact its tectonic framework is poorly known. To learn more about this topic, we carried out an original structural analysis on Pleistocene deposits. The results indicate that southern Apulia has been affected by mild but discernible brittle deformation throughout the Middle and Late Pleistocene. Joints prevail, whereas faults are rare and all characterized by small displacement. Horizontal extension dominates throughout the entire study area; the SW-NE to SSW-NNE direction is the most widespread. WNW-ESE extension prevails in the Adriatic side portion of the study area, but the dispersion of the measured plane directions is high, suggesting that the local strain field is not characterized by a strongly predominant trend. A Middle and Late Pleistocene, SW-NE to SSW-NNE– oriented maximum extension is not surprising for the study area, as it is compatible with most of the available geodynamic models, whereas the different state of deformation affecting the Adriatic side of the study area requires further investigations. We tentatively interpreted this anomaly as reflecting some regional variation of the general geodynamic frame, for instance as the farthest evidence of ongoing compressional deformation across the W-verging Albanide-Hellenide foldand- thrust belt.

    Geodatabase e report di sismicità (2010)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: The laboratory of digital cartography and geographical information systems (LABGIS) of the ISTITUTO NAZIONALE di GEOFISICA e VULCANOLOGIA (INGV) in Grottaminarda (AV) has focused its activity on the organization and processing of a high number of cartographic, territorial, geological and geophysical data regarding Central and Southern Italy. This activity represents one of the purposes of CESIS Project whose aims are to realize a monitoring network of permanent stations with seismic, accelerometric and geodetic instruments and to create a Centre for Seismology and Seismic Engineering. The realization of a series of geographical database in ESRI Geodatabase data model with the software ArcGIS 9 has offered the possibility of trying out the opportunities of this technology as, for example, the organization of different types of geographical data and proceedings inside the same environment. The following step was to develop a series of applications as the SIT CESIS EARTHQUAKE REPORT. This application produces a cartographic report, which is able to give a territorial and seismological view for each earthquake of magnitude greater than 3.0 recorded in Southern Italy. The report contains information deriving from the historical and instrumental seismicity catalogues and information about the location of monitoring network stations, the seismic hazard and classification. All these data are produced by the INGV. This instrument is very important for the activity of seismic monitoring because it is able to give an immediate and complete answer, regarding to an occurred earthquake to the National Department of Civil Protection. That’s why it has been thought to extent the creation of a report to all the national territory, by increasing the database and developing a specific GIS application that can be used, in real time, in the seismic monitoring hall of the Centro Nazionale Terremoti in Rome.

    Il sistema informativo territoriale della Rete Integrata Nazionale GPS (RING) (2010)
    Società Geologica Italiana
    Details
    Publication Date: 2017-04-04
    Description: Since 2004, an important technological infrastructure has been created in Italy by INGV in order to investigate active tectonics targets. A Continuous GPS network constituted by about 130 stations has been deployed all over Italy. The development and the realization of a stable GPS monumentation, the integration with other classical seismological instruments and the choice of both satellite and internet data transmission make this network one of the most innovative and reliable CGPS networks in the world. The development of the CGPS network has been accompanied by a technologically advanced development of all the aspects related to the data acquisition and the data information mining: a database and a SIT. Based on the recent techniques of Knowledge Management, the database has been developed to manage the data and the data information of all the sites of the RING network, thus allowing us to centralize information in a single common data bank and to create an unique service of access point to the data from different remote sites by internet connections. The SIT has been developed to be fully integrated with the Knowledge Management technology and it is aimed to synthesize and to display in a geographic interface the information of the RING sites. This work has been integrated with all other spatial data, such as topographic and geo-thematic maps, geological, seismological and seismo-tectonic databases. In this work, the technological aspects of the SIT of the RING network will be detailed and some examples of thematic maps will be shown.

    Limited overlap between the seismic gap and coseismic slip of the great 2010 Chile earthquake (2011)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: The MW 8.8 mega-thrust earthquake and tsunami that occurred on February 27, 2010, offshore Maule region, Chile, was not unexpected. A clearly identified seismic gap existed in an area where tectonic loading has been accumulating since the great 1835 earthquake experienced and described by Darwin during the voyage of the Beagle. Here we jointly invert tsunami and geodetic data (InSAR, GPS, land-level changes), to derive a robust model for the co-seismic slip distribution and induced co-seismic stress changes, and compare them to past earthquakes and the pre-seismic locking distribution. We aim to assess if the Maule earthquake has filled the Darwin gap, decreasing the probability of a future shock . We find that the main slip patch is located to the north of the gap, overlapping the rupture zone of the MW 8.0 1928 earthquake, and that a secondary concentration of slip occurred to the south; the Darwin gap was only partially filled and a zone of high pre-seismic locking remains unbroken. This observation is not consistent with the assumption that distributions of seismic rupture might be correlated with pre-seismic locking, potentially allowing the anticipation of slip distributions in seismic gaps. Moreover, increased stress on this unbroken patch might have increased the probability of another major to great earthquake there in the near future.

    Lava flow hazards at Mount Etna: constraints imposed by eruptive history and numerical simulations (2014)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: Improving lava flow hazard assessment is one of the most important and challenging fields of volcanology, and has an immediate and practical impact on society. Here, we present a methodology for the quantitative assessment of lava flow hazards based on a combination of field data, numerical simulations and probability analyses. With the extensive data available on historic eruptions of Mt. Etna, going back over 2000 years, it has been possible to construct two hazard maps, one for flank and the other for summit eruptions, allowing a quantitative analysis of the most likely future courses of lava flows. The effective use of hazard maps of Etna may help in minimizing the damage from volcanic eruptions through correct land use in densely urbanized area with a population of almost one million people. Although this study was conducted on Mt. Etna, the approach used is designed to be applicable to other volcanic areas.
    Description: This work was developed within the framework of TecnoLab, the Laboratory for Technological Advance in Volcano Geophysics organized by INGV-CT, DIEES-UNICT, and DMI-UNICT.
