The analysis of the landscape evolution before and after a landslide is of paramount importance for investigating the landslide itself and the effects on the involved area. Such analysis can be particularly sharp, when high resolution digital elevation models, e.g. LiDAR, are available at multiple time steps, before and after the event. This work presents some preliminary results of a quantitative geomorphic analysis based on 2D discrete wavelet transform of two LiDARs, ante and post event. In particular, the large landslide of Montescaglioso, south Italy, is investigated. This landslide is a complex large movement, which involved a relatively poor steeping clay slope. Numerical results of this analysis will emphasize the magnitude of variations between the ante and post landslide scenarios
