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