  1. 5. Geological and geoelectrical survey of the metamorphic and intrusive rocks on the Einstein Telescope site (Sardinia, Italy)
    Dr Giovanni Luca Cardello (INFN Catania)
    08/11/2021, 09:00
    Talk

    The geological characterization preceding the construction of a large-scale underground structure, such as the Einstein Telescope (ET), is a mandatory step of civil engineering studies. The ET Italian candidate site is located in the Variscan basement of Sardinia because of its geodynamic quietness, very low seismicity and anthropogenic seismic noise. The ET layout is currently projected as an...

  2. 6. Geophysical characterization of the shallow subsurface in sites P2 and P3 from high-resolution active-source seismic profiling and downhole data: preliminary results
    Dr Fabio Villani (Istituto Nazionale di Geofisica e Vulcanologia)
    08/11/2021, 10:00
    Talk

    In the framework of the Project Einstein Telescope Sos Enattos, we report the preliminary results of the active-source seismic surveys performed by the INGV team in sites P2 (labelled as Onani) and P3 (labelled as Bitti) in July and September 2021. The main goal of these surveys was the reconstruction of the shallow subsurface velocity structure in correspondence of the two drilling sites....

  3. 29. Summary of long term seismic characterization activities at Sos Enattos
    Matteo Di Giovanni (Istituto Nazionale di Fisica Nucleare)
    08/11/2021, 10:30
    Talk

    During the last two years, Sos Enattos has been the subject of an extensive seismic characterization campaign with the installation of several permanent and temporary seismic stations. In this presentation, I will give an overview of this long-term characterization campaign highlighting the main results that have been obtained so far, including the very low noise levels that have been measured...

  4. 27. Environmental noise measurements at Sos Enattos
    Rosario De Rosa (Istituto Nazionale di Fisica Nucleare)
    08/11/2021, 11:30
    Talk

    In this talk I present an update of the long term measurement campaign
    going on in Sardinia, for the environmental noise characterization of the
    ET candidate vertexes. I will mainly focus on the magnetic noise measured
    both in surface and underground of the Sos Enattos site, as well as in P2
    (Bitti). A comparison of the Schumann resonances behavior in both sites
    and a projection of their...

  5. 25. Array analyses of the seismic noise wavefield at the possible vertices of the Einstein Telescope in Sardinia (Italy)
    Gilberto Saccorotti (Istituto Nazionale di Geofisica e Vulcanologia)
    08/11/2021, 12:00
    Talk

    The region surrounding the dismissed mine of Sos Enattos (Sardinia, Italy) is the Italian candidate site for hosting Einstein Telescope (ET), the next-generation gravitational wave (GW) detector. The site that will host ET must fulfill stringent requirements on seismic disturbances, particularly in the bandwidth 1-10 Hz, where the seismic noise is expected to be dominated by sources of...

  6. 19. Preliminary results from the boreholes at the ET corners in Sardinia
    Dr Luca Naticchioni (INFN Roma)
    08/11/2021, 12:30
    Talk

    In this talk we discuss the preparation of two boreholes at the corners, named P2 and P3, of the ET triangle in Sardinia. The boreholes are designed to host broadband seismometers dedicated to a long-term seismic monitoring at about 250m underground. We also report the principal aspects of the geophysical logs of the boreholes and the sensor installation downhole. Finally, we present the...
