Since 2014, the Center for Seismological Research (CRS) of OGS has been involved in the setting up and implementation of a network of permanent GNSS stations for the characterization and monitoring of landslides upstream from the village of Cazzaso in the municipality of Tolmezzo (UD). To date, 14 stations are active. The monitoring system can estimate the movements, with a one-hour delay, and to ensure a timely notification to the local administration, which can manage the access routes and the possible evacuation of a residential area.

The monitoring activity is supported with funds from the municipality of Tolmezzo regulated by various agreements covering the period from the beginning of 2015 to the end of 2026:

Thanks to the work carried out, OGS was recognized with the “Conoscere per prevenzione 2016” award for the project “The Esri Italia GNSS monitoring system SENDAS: the case history of the Tolmezzo (UD) landslide”. Award assigned by the Scientific Committee of the Esri Italia 2016 Conference on 20 April 2016 at the Leptis Magna Hall of the Ergife Palace Hotel in Rome, https://www.ogs.it/it/notizie/27-aprile-esri-italia-premia-logs

 also monitored, on behalf of the FVG Civil Protection, the left bank of the Livenza River near the town of Brugnera (PN) by means of a network of permanent GNSS stations. The activity was summarized in the works indicated below:
