AB The Jerte Valley is a northeast-southwest tending graben located in the mountainousregion of west central Spain (Spanish Central System). Mass movements have been a predominantshaping process on the Valley slopes during the Quaternary. Present day activity is characterized aseither ‘first-time failure’ (shallow debris slides and debris flows) or ‘reactivations’ of pre-existinglandslides deposits.A delineation of landslide hazard zoning within the Valley has been carried out by using the detaileddocumentation of a particular event (a debris slide and a sequel torrential flood, which occurredon the Jubaguerra stream gorge), and GIS techniques. The procedure has had four stages, which are:(1) the elaboration of a susceptibility map (spatial prediction) of landslides; (2) the elaboration of amap of ‘restricted susceptibility’ in the particular case of slopes that are connected to streams andtorrents (gorges); (3) the elaboration of a digital model which relates the altitude to the occurrenceprobability of those particular precipitation conditions which characterized the Jubaguerra event and(4) the combination of the probability model with the ‘restricted susceptibility map’, to establish‘critical zones’ or areas which are more prone to the occurrence of phenomena that have sametypology as this one.
