SMINO contributes to fulfilling the CRS institutional tasks, which, as provided by law 399/1989, has the task of surveillance and research on seismic activity in North-eastern Italy, also for Civil Protection purposes.
SMINO consists of a seismic network, a strong motion network and a geodetic monitoring network (FReDNet). SMINO is an infrastructure of national importance (PNIR 2021-2027).
SMINO operates in close cooperation with national and international networks in neighbouring countries, under framework agreements for real-time data exchange. Information on seismic events is disseminated to the public through a dedicated web portal dedicated web portal.
Seismic bulletins containing information on earthquakes recorded in North-eastern Italy are published regularly.
North-East Italy Seismometer Network
The North-eastern Italy Seismic Network consists of 43 stations, of which 24 broadband, 15 short-period and 4 intermediate-period. The Network is managed by OGS also on behalf of the Friuli Venezia Giulia and Veneto Regions. The stations are installed in Friuli Venezia Giulia, Veneto (in most cases), Emilia Romagna and Lombardy. The data recorded by all the stations are acquired in real time at the OGS Centre for Seismological Research in Udine.
The Network also provides data to the national seismic surveillance system, with real-time data exchange with the Civil Protection Department and the National Institute of Geophysics and Volcanology (INGV). Moreover, in order to improve the quality of localizations and magnitude estimation in border regions, the Network exchanges real-time data with the seismic networks of Austria, Slovenia, Switzerland, and the Autonomous Provinces of Trento and Bolzano, and the University of Genoa.
The North-eastern Italy Seismic Network is part of the CE3RN cross-border network in which also the seismic networks of Croatia, Slovakia, Hungary, Romania, Albania and Bulgaria participate. CE3RN is an example of excellence in transnational collaboration and sharing of infrastructure, data and resources. Network data are made available through OASIS, EIDA and the RTS system.
Strong motion Network
In order to guarantee the correct recording also of strong seismic events, 29 stations of the seismic network were also equipped with high quality strong motion sensors. Moreover, within the "Sentinel Buildings" projects financed by the Regional Civil Protection of the Autonomous Region of Friuli Venezia Giulia and the Interreg V-A Italy-Austria project Armonia, and the Venet-one project, other medium cost strong motion sensors (more than 100) have been installed. The network data are acquired in real time and their processing contributes to the rapid estimation of the impact of seismic events.
Friuli Regional Deformation Network (FReDNet)
FReDNet (Friuli Regional Deformation Network) is the crustal deformation monitoring system in Friuli Venezia Giulia that the Centre for Seismological Research began developing in 2002, with the installation of the first station. In most cases the receivers have been installed in sites already hosting the sensors of the OGS seismic network. FReDNet is also part of a wider programme of geodetic survey of the Adriatic microplate that includes the repetition of episodic measurements of geodetic points.
FReDNet currently comprises 19 permanent GNSS receivers (GPS+GLONASS+Galileo) for geodetic monitoring of crustal deformations in North-eastern Italy. It also provides a service for high-precision georeferenced navigation in real time according to differential correction modes (RTK - Real Time Kinematic, MRS - Multi Reference Station and VRS - Virtual Reference Station). The service is freely accessible to public, private and scientific users. The Network is integrated with the GPS network of the Friuli Venezia Giulia Region, with the National Dynamic Network of the Military Geographic Institute and with the European EUREF Permanent Network.
FReDNet is included in EPOS RIDE.
