Analysis of the rainfall preceding the activation of the large Maierato landslide in 2010

This work focuses on the impact of the antecedent rainfall as triggering factor of the large landslide occurred in Maierato (south Italy) on February 15, 2010. According to previous studies by Guerricchio et al. (2010) the predisposing factor of the landslide is an ancient deep-seated gravitational slope deformation that significantly affected landforms, drainage networks and infiltration processes of the whole slope where Maierato is located. Here after a brief introduction of the landslide according to the aforementioned study, an hydrological analysis of the rainfall preceding the landslide is presented. The analysis aims at evaluating the exceptionality and some peculiar characters of rainfall, which may be considered among the triggering factors of the landslide.
