| Popis: | In this paper we illustrate the state of the art of the European Co-operation in the Field of Scientific and Technical Research, COST Action 625 “3-D Monitoring of Active Tectonic Structures” in Italy. The project is mainly focused on detecting strain variations and/or any phenomena that may precede future seismic events, in order to evaluate the time evolution and modes of deformation of seismogenic structures during the inter-coseismic cycles. We selected two note seismic areas, (i) the Gargano promontory (southern Italy) and (ii) the Norcia basin (central Italy), for the installation of a monitoring equipment consisting of: (a) local networks of geodetic stations (benchmark for GPS and total station measurements with micrometric sensitivity) and (b) 3D monitoring devices (TM71; capable of recording micrometric displacements). In this paper we show the geo-structural analysis and detailed morphostructural studies, including high-resolution seismic reflection profiles and paleoseismological investigations, carried out across the main active faults of selected areas, which allowed us to assess the main spatial and dimensional properties of faults. As concerns the monitoring experiment, available data are not yet adequate to be used for convincing tectonic interpretations because the installation of local GPS stations and that of TM71 extensometers has been carried out only very recently. Accordingly, we only show a few examples of microdisplacement measurements carried out in both areas. |
