CRISP: an archive for the site characterization of permanent Italian seismic stations

In this paper we describe an advanced database for the site characterization of seismic stations,
named “CRISP—Caratterizzazione della RIsposta sismica dei Siti Permanenti della
rete sismica” (http:// crisp. ingv. it, quoted with https:// doi. org/ 10. 13127/ crisp), designed for
the Italian National Seismic Network (Rete Sismica Nazionale, RSN, operated by Istituto
Nazionale di Geofisica e Vulcanologia). For each site, CRISP collects easily accessible station
information, such as position, type(s) of instrumentation, instrument housing, thematic
map(s) and descriptive attributes (e.g., geological characteristics, etc.), seismic analysis
of recordings, and available geophysical investigations (shear-wave velocity [VS] profile,
non-linear decay curve). The archive also provides key proxy indicators derived from the
available data, such as the time-averaged shear-wave velocity of the upper 30 m from the
surface (
VS30) and site and topographic classes according to the different seismic codes.
Standardized procedures have been applied as motivated by the need for a homogenous set
of information for all the stations. According to European Plate Observing System infrastructural
objectives for the standardization of seismological data, CRISP is integrated into
pre-existing INGV instrument infrastructures, shares content with the Italian Accelerometric
Archive, and complies map information about the stations, as well as local geology,
through web services managed by Istituto Superiore per la Protezione e la Ricerca Ambientale.
The design of the CRISP archive allows the database to be continually updated and
expanded whenever new data are available from the scientific community, such as the ones
related to new seismic stations, map information, geophysical surveys, and seismological
analyses.
