Abstract

The paper focuses on the evaluation of the technical performance of the landslide warning system operating, at regional scale, in the Campania region. The test area of the case study is one of the eight warning zones adopted by the regional civil protection agency to warn citizens for both extreme rainfall conditions and rainfall-related landslides and floods. The simulations performed herein compare two different warning strategies, which are based on measures of cumulated rainfall over different lengths of time, using rainfall data and landslide occurrences referring to the four-year time frame 2010–2013. The performance evaluation is conducted applying the EDuMaP method [1], which is based on the computation of a duration matrix reporting the time associated with the occurrence of landslide events in relation to warning events, in their respective classes.
