The CRISP archive (acronym for “Caratterizzazione della RIsposta sismica dei Siti Permanenti della rete
sismica” - “Site characterization of the permanent seismic stations ”) is an integrated database that brings
together all the information useful for the seismic characterization of sites of the Italian National Seismic
Network, to provide the maximum knowledge available in an easily accessible way. The archive for a single
site collects information on position, instrumentation, instrument housing, map, geological characteristics,
seismic analysis, geophysical investigation, site classification. Field values come from already available
information or ad-hoc analysis.
Details on database and front end can be found in Menu Bar - About - Documentation.
CRISP is a "work in progress" project and it is open to later additions and improvements. All new entries
are recognisable via the last update field.

Abstract:A field experiment with small aperture seismic arrays was performed on the unstable rock slope above the village of Randa in the southern Swiss Alps. The aim of this experiment was to constrain the seismic response of a potential future rockslide using ambient vibration recordings. Weak seismic events were identified on the recordings and site-to-reference spectral ratios were calculated using a reference site located on the stable part of the slope. Spectral ratios of up to 30 were observed at sites located within the unstable portion of the slope. A strong variation of spectral ratios with azimuth indicates a directional site effect. Neither amplification nor directionality were observed at sites located in the stable part of the slope. Furthermore, time-frequency polarization analysis of the ambient noise was performed to provide robust estimates of frequency dependent directions of the maximum polarization. It was found that the unstable part of the slope vibrates within a narrow range of directions (130 ± 10°) for the frequency range centred around 5 Hz. The polarization directions estimated from ambient seismic vibrations are in good agreement with the deformation directions obtained by geodetic and in situ measurements. No directionality of ambient vibrations was observed at sites within the stable part of the slope.
