Session 2.2 GNGTS 2023 CRISP database for site characterization of the permanent Italian seismic network G. Cultrera, A. Mercuri, M. Quintiliani, L. Minarelli, D. Famiani, P. Casale, M. Pischiutta, C. Ladina, F. Cara, G. Di Giulio, S. Pucillo, G. Tarabusi, CRISP Working Group Istituto Nazionale di Geofisica e Vulcanologia, Italy The CRISP database, acronym for “Caratterizzazione della RIsposta sismica dei Siti Permanenti della rete sismica”, is a new archive dedicated to site information of all the stations of the Italian National Seismic Network (Rete Sismica Nazionale, RSN), the nationwide permanent seismological network operated by the Istituto Nazionale di Geofisica e Vulcanologia - INGV. The database (http://crisp.ingv.it; Cultrera et al., 2022, Mercuri et al., 2022) is organized to contain all the information useful for the site characterization, such as: - thematic maps on geological characteristics; - Information on station and housing: location, instrumentation, data quality, housing type; - geological data under and around the station: stratigraphy, geological review, morphological, lithological and geological classification, cross section; - seismic analysis on recordings: spectral ratio on noise and earthquake, polarization analysis; - geophysical investigations: Vs profile, non linear curve; - topography and soil classes. The physical database was implemented by the DBMS PostgreSQL/PostGIS which is integrated in a web application with GIS functionality (Geographical Information System), and it is the result of in-depth discussion in a large group of experts on related topics: geologists, seismologists, engineers, IT specialists. Through the website, it is possible to access all the stations and the relative information, and to use a simple query mask for selecting the stations that match search criteria such as: Vs30, site classification, spectral ratio peaks, available cartography, housing. Soon available specific APIs will allow you to download all the data through a command line. CRISP is populated with heterogeneous data coming from pre-existing INGV archives, or specifically computed with standardized procedures for having a homogenous set of information at all the stations. It receives the maps around the stations and information on the local geology through web services managed by Istituto Superiore per la Protezione e la Ricerca Ambientale
