Resumen

The vulnerability of man and his heritage to natural phenomena in the southern highlands of Peru has increased considerably, especially in the study area. The confirmation of this assertion, which for a large part of the population turns out to be still a hypothesis, forces us to reflect on the schemes foreshadowed by the government agencies related to the subject, in terms of seriously considering why these disasters are less and less natural and what would be the most appropriate management for the risk of landslide. The present case study reaffirms that the interrelation of the physical and social media over time is something that is no longer questioned. This paper analyzes the regionalization of natural phenomena, essential for landslide risk assessment and management. A geotechnical zoning of the case study was carried out based on the geomorphological and soil mechanics study. Likewise, the compilation of the investigations carried out previously in the area, from the field explorations and the results of laboratory tests. Five microzones were identified and the geotechnical hazard zoning concluded with three well-framed danger zones.
