Resumen

Landslide phenomena frequently occur in environmental limits, as is the case of riverside areas, these are due to anthropogenic factors such as cutting operations, dumping of substances, removal of vegetation cover, disorganized growth of the population that leads to construction next to slopes, producing a negative impact on the environment. In addition, the influence of seismic, morphological and climatological factors, added to the anthropogenic factors, make the environment susceptible to the occurrence of slope landslides, being of great importance the understanding of the human perception in these inhabited areas in order to implement unconventional stabilization methods that mean sustainable, efficient, low-cost alternatives and that achieve the expectations of the inhabitants. This research is carried out in the sector of Santa Cruz de Lara, an area consolidated on a slope near to the Socabaya River in Arequipa, which represents a highly vulnerable area to the occurrence of landslides, however, it presents a strong rooted population. The identification of latent risks was carried out, in terms of physical factors such as topographic survey, field exploration of the study area, as well as the physical-mechanical characterization of the soils present to understand the nature and behavior of the soil. Social factors were evaluated in the study area, through observation and a 25-question interview, based on the Geo-SAT tool (Geotechnical Sustainability Assessment), which includes the population's perception of landslide risk. According to the results analyzed, it can be observed that the study area is vulnerable to the incidence of landslides, however, the population has deep social roots in the area and does not consider moving, since they consider the area to be safe. The study highlights promoting policies to improve infrastructure to prevent possible landslides and reduce the vulnerability of the population.
