contents The Torvizcón, Spain, landslide of February 1996: the role of lithology in a semi-arid climate Irasema Alcántara Ayala Ciencias de la Tierra back analysis Shallow failures metamorphic terrains sensitivity analysis infinite slope model The analysis of a shallow landslide in las Alpujarras, a metamorphic terrain of semi-arid Spain is presented. The extensiveoutcropping of phyllites and mica-schist is one of the most important keys in the understanding of mass failure. The degree ofschistosity offers planes of weakness where water can penetrate and cause mass movement processes by increasing pore waterpressures. A shallow slope movement occurred during extreme events, causing damage to the local and regional infrastructure andincreasing the likelihood of natural disasters. By using the infinite slope model of Skempton and DeLory, a back analysis of anobserved shallow landslide was carried out. The results of the sensitivity analysis indicated that material properties play a significantrole in controlling slope processes and that the slope angle should not be considered as the only parameter to define instabilitythreshold. 1999 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56838305 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.38
