Interactive comment on “An assessment of landslide distribution in the Faifa area, Saudi Arabia, using remote sensing and GIS techniques” by T. Alharbi et al.

摘要: The paper presents surely an interesting approach in the use of remote sensing data applied in the areas where the field investigations are very hard. However there are, in my opinion, several aspects which need a substantial revision. The main critical point is related to the generation of landslide hazard maps. The authors, in fact, obtain three maps of landslide hazard (related to debris flows in ephemeral valleys, overland debris flows on sparsely vegetated slopes and landslides caused by failure along fracture planes). These maps are generated on the base of an interesting methodological approach, but the final finding is a map where the danger levels aren’t identified and
