URL: http://www.cnr.it/prodotto/i/404878

The document, which represents the fourth deliverable of WP4 "Tools and methods to support Early Warning System for Rock falls", describes the actions performed in the Activity 4.5 "Rainfall thresholds for the possible initiation of rock falls". The main goal of this activity is the definition of empirical rainfall thresholds for the possible initiation of rock falls in the Canary Islands. The report describes the empirical cumulated event rainfall - rainfall duration (ED) thresholds for the Gran Canaria and Tenerife test sites. For the purpose, a tool for the objective and reproducible reconstruction of rainfall events and of rainfall conditions responsible for rock falls is used. A frequentist statistical method is adopted to define ED thresholds for different non-exceedance probabilities.
