Prof. Michele Calvello Introduction Multiple rainfall-triggered shallow landslides Mangawhero, New Zealand (2004) Catanzaro, Italy (2010) susceptibility (Fell et al. 2008) A quantitative or qualitative assessment of the, volume (or area), and spatial distribution of landslides which exist or potentially may occur in an area. Susceptibility zoning by statistical (data driven) methods Fell et al. (2008). Guidelines for landslide susceptibility, hazard and risk zoning for land-use planning. Engineering Geology 102:

(2013) Procedure proposed to produce landslide distribution zoning Definition of scale-dependent terrain computational units () related to the spatial resolution of the map Territorial domains used to define, calibrate and/or validate a model for landslide terrain zoning units (TZUs) related to the desired informative resolution of the zoning TZUs Territorial domains used to produce a landslide map for zoning purposes Calvello M, Cascini L, Mastroianni S (2013) zoning over large areas from a sample by means of scale-dependent terrain units.

Prof. Michele Calvello The proposed method: landslide susceptibility assessment by means of statistical Derive and choose a set of optimal independent from a set of thematic Input data From thematic to numerical to independent statistical i.e. correlation between the dependent and each independent landslide susceptibility to relevant to optimal spatial of relevant ( of ROC curves) Mutivariate statistical i.e. correlation between the dependent and a series of relevant independent landslide susceptibility
8 susceptibility assessment by means of statistical ISL 2016, Napoli (Italy). Prof. Michele Calvello The case study Test area (southern Italy) Multiple rainfall-triggered shallow landslides Two small catchments approximately 8 km 2 on the left bank of the Corace river Thickness from 3 to 15 m. Length from 10 to 100 m. Depth of the sliding surface from a few decimetres to 3 m. The biggest ones are prevalently localized in morphological hollows
9 information employed for the analysis DEM, river network and landslide Geo-structural map Weathered rock thickness map physical weathering 1.0 m Weathered rock Year landslide source areas 2. landslide propagation zones 429 phenomena classified as shallow earth slides or earth slides earth flows 1. holocene alluvial deposits 2. holocene colluvial 3. holocene landslide debris 4. Pliocene light blue-grey silty clays 5. pleistocene sandstone 6. plio-pleistocene sands and clays 7. Normal faults 8. strike-slip faults Slaking consists of the alternate process of rocks wetting and drying. It produces two types of disintegration (Ollier 1994): minor disintegration Pattern of cracks due to flaking, major disintegration due to the splitting of the sample into large pieces. Blight (1997) susceptibility assessment by means of statistical ISL 2016, Napoli (Italy). Prof. Michele Calvello The case study

17 susceptibility assessment by means of statistical ISL 2016, Napoli (Italy). Prof. Michele Calvello Concluding remarks On the case study The results of the performed show that: i) the best criterion, of the two adopted herein, is natural breaks; ii) iii) β and σ values related to the of the ( 1) almost always assume values substantially higher than those obtained from the native ( =1); for each significant independent, the values of are not considerably influenced by the criterion nor by the value assumed by. On the proposed method The landslide susceptibility s obtained with and without processing (in the various s) showed significant differences in terms of success of the analysis, as testified by the changes in values of the two indicators S 10 and E 90. The approach can be also successfully used to get landslide susceptibility zoning (Ciurleo et al., 2016)
