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

Abstract
The document, which represents the fourth deliverable of WP4 "Tools and methods to support Early Warning System for Rockfalls", describes the actions performed in the Activity 4.5 "Rainfall thresholds for the possible initiation of rockfalls". The main goal of this activity is the definition of empirical rainfall thresholds for the possible initiation of rockfalls in the Canary Islands. The report describes the preliminary empirical cumulated event rainfall - rainfall duration (ED) thresholds for the Gran Canaria and Tenerife test sites. For the purpose, an algorithm for the objective and reproducible reconstruction of rainfall events and of rainfall conditions responsible for rockfalls is used. A frequentist statistical method is adopted to define ED thresholds for different exceedance probabilities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
