Landslide Science and Practice: Landslide Inventory and Susceptibility and Hazard Zoning | Year: 2013

Arpa Piemonte is in charge of the maintenance of the framework about the hydrogeological instability of the Piemonte region. One of the main goal of working package B2 of the ALCOTRA European Project RISKNAT is focused to improve the knowledge of the SIFRAP (the landslide inventory of Piedmont region), in particular on the more serious phenomena where detailed examination is needed. The update is mainly carried out by the integration of different kind of data in order to obtain an effective knowledge of phenomena: detailed morphological analysis, carried out mainly by air-photo interpretation and some aimed field survey, are coupled with the outcome of the monitoring system of Arpa Piemonte. Thanks to the found of RISKNAT project also space borne radars data are available: in 2010, we covered an Alpine area of about 13,000 km2 using data sets from Canadian RADARSAT satellite, covering the time span from 2002 to 2009. The survey was made using a newly patented processing algorithm (the SqueeSAR™) and identified more than 2 millions PS. Also a previous in coverage was made over the entire region (~25,000 km2) using data sets from ERS-1 and ERS-2 radar satellites, covering the time span from 1992 to 2001. The main activity is now pointed out to analyse and integrate together all these different data in order to obtain meaningful landslides interpretations and an efficient way to make available all data to citizen and regional authorities. © Springer-Verlag Berlin Heidelberg 2013.
