Province of Biella — BDG Frane quiescenti

The dataset represents the identification (polygonal or punctual) of quiescent landslides; this term defines landslides that have given signs of life in a period prior to the last 30 years. The classification adopted for the landslides database is based on the tripartition used for mapping P.A.I (Fa, Fq, Fs). When allocating the landslides recorded for Biella for the mapping of the P.A.I, care was taken to use the information on the date of occurrence, where available, and, in the many cases of unknown date of origin, the status of activity attributed according to the classification of Cruden and Varnes was interpreted, adapting it to the need for homogeneity of the Po River Basin Plan.The quiescent landslides are represented in the MA3a cartography (Environmental Matrix), IGT-S (Provincial Territorial Plan); the methods of elaboration and analysis of the results obtained are reported in the Environmental Matrice report: Physiography and Environmental Danger.
