Final version accepted: 28 September 2011. Patricia Flores* Irasema Alcántara Ayala** Abstract.
Owing to the mountainous character of the Mexican terrain, as well as the ecological effects of changes in land use, particularly in recent decades, and the occurrence of severe and frequent hydro-meteorological phenomena, the instability of slopes dislodged by precipitation constitutes a major hazard in various regions of the country, among them the municipality of Temoaya in the State of Mexico. In this municipality, where the mountainous relief formed by poorly consolidated and faulting volcaniclastic deposits favours instability, there are 33 active processes of mass movement, of which thirty –the most important– are shallow soil translational landslides (SSTL), one is a debris slide and two are rock falls.
The occurrence of SSTLs is controlled by the character of the volcaniclastic deposits, specifically pyroclastic flows of blocks, ash and pumice; because these are permeable materials they favour infiltration...
