GNGTS 2018 - 37° Convegno Nazionale

GNGTS 2018 S essione 3.2 631 • N. 1 bi-dimensional passive seismic array, using a Geode seismograph (Geometrics) and 4.5 Hz geophones, processed with Extended Spatial Auto-Correlation (ESAC) technique; • 15 single station seismic ambient noise measurements acquired by a 24 bit digital tromograph Moho-Tromino and analyzed with the Horizontal-to-Vertical Noise Spectral Ratio (HVNSR); • local and regional earthquake recordings by accelerometers (SARA-Electronic Instruments SL06 with 1g full scale) in two sites analyzed by means of Horizontal-to-Vertical Spectral Ratio (HVSR). A detailed description of the methods used is given elsewhere (Calamita et al. , 2018). Results and discussions. From a qualitative viewpoint, the full resolution COSMO-SkyMed (CSK) SBAS-DInSAR velocity map (Fig. 2) do not show any significant deformation pattern, thus revealing a general stable behaviour of the entire urban area in the investigated period. However, some localized displacements of 3-4 mm/year are detected for some buildings and Fig. 1 - [a] Sketch map of geophysical and geotechnical survey locations superposed to the geological map of the urban area of Avigliano (PZ).
