This study attempts a comprehensive review of the casual factors, which are controlling the frequent slope failures in the Miocene sediments at the Villalonquejar area (Burgos). For the purpose, an extensive study o f both field and laboratory study of weathered and unweathered material was undertaken. The study involved insitu observation of both natural and artificially cut slopes, (mechanism, typologies and failure condition) as well as a survey of some of their engineering properties. The effect o f this process has been estimated using, laboratory test and slope stability analysis considering a circular failure. The results have shown that the main process of slope instability in these sediments is degradation and erosion due to wetting-drying cycles.
