As a result, the prediction of shallow slope failures triggered by intense or prolonged rainfall is of\nprimary importance for decision makers and civil protection authorities. At the national and the regional scales,\nthe prediction of the possible occurrence of rainfall induced shallow landslides is achieved by comparing rainfall\nmeasurements and estimates with empirical rainfall thresholds, established through the analysis of past rainfall\nevents that have resulted in slope instabilities. Using multiple sources of information (including newspapers and\nfire brigade reports), we have updated an historical catalogue listing > 500 rainfall events that have resulted in\ndocumented landslides in the Abruzzo, Marche and Umbria regions, central Italy, between 2002 and 2011. We\nhave exploited this catalogue to determine new cumulated event rainfall - rainfall duration (ED) thresholds for\nthe possible occurrence of slope failures in central Italy. It is known that the local topographical (morphological),\nlithological, soil and climatic settings condition the occurrence and spatial distribution of shallow landslides in an\narea. For this work, we have exploited the catalogue of rainfall events with landslides to investigate the role of\nmorphology and soil types in the cumulated amount (E) and the duration (D) of the rainfall that has resulted in\nshallow landslides in our study area, in the 10-year considered period. For the purpose, we have subdivided the\nstudy area in 3 topographic sub-divisions and 7 regional soil domains, and we have analysed the (D,E) rainfall\nconditions in the two different terrain classifications. Adopting a Frequentist statistical method already used to define\nlithological and climatic thresholds in the study area, and their associated uncertainties, we have defined new\nED rainfall thresholds for possible landslide occurrence for the individual topographic sub-divisions and regional\nsoil domains. The new thresholds were compared with the existing geographical, lithological, and climatological\nthresholds in the same study area. We expect the results of this study to contribute to the understanding of the\ninfluence of topography and soil characteristics on the occurrence and spatial pattern of rainfall induced shallow\nlandslides in central Italy. We further expect that the new topographic and soil thresholds can improve the ability\nto forecast shallow landslides in central Italy, and in neighbouring and distant areas characterized by similar\nmorphological and soil settings."@en ; prodottidellaricerca:prodottoDi modulo:ID2915 , istituto:CDS066 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA33010 , unitaDiPersonaleInterno:MATRICOLA10859 , unitaDiPersonaleInterno:MATRICOLA14259 . ns11:ID47821 pubblicazioni:rivistaDi prodotto:ID192326 .
