GNGTS 2019 - Atti del 38° Convegno Nazionale

GNGTS 2019 S essione 2.1 291 eu.org/ ), designed to archive strong-motion data of magnitude M >4, recorded in the European- Mediterranean and the middle-East regions. The different versions of ITACA released over the years testify the great effort invested to its development and, in particular, to: 1) populate the database; 2) standardize waveforms and metadata formats according to the Federation of Digital Seismograph Networks (FDSN https://www.fdsn.org/networks/ ); 3) process the signals by means of standard procedures; 4) create queries for exploring events, stations, and waveforms metadata; 5) access and download accelerometric waveforms and related metadata; 6) select suites of spectrum-compatible ground-motion waveforms; 7) provide seismological products useful for the calibration of ground-motion models. The ITACA target users are researchers and students in the fields of applied seismology and earthquake engineering, professional engineers or geologists and policy makers. The number of users has grown over time, every day ITACA is visited by nearly 250 unique users. A considerable number of scientific papers is directly or indirectly linked to the ITACA services or products (Luzi et al. , 2009; Paolucci et al. , 2010; Pacor et al. , 2011; Bindi et al. , 2011; Puglia et al. , 2018 among others).
