The study conducted in 'Quebrada del Diablo' ravine, located in the Tacna region, Peru, reveals high levels of vulnerability in the human settlements of this area. Vulnerabilities were identified in environmental, physical, economic, social, educational, and cultural aspects using the methodology proposed by the National Institute of Civil Defense. Additionally, sedimentary, morphodynamic, and geodynamic hazards levels were evaluated through thematic maps. Factors contributing to vulnerability include solid waste pollution, the construction of substandard housing, lack of preparedness in risk prevention, and limited awareness of the dangers present in the area. Particularly, El Mirador Human Settlement showed a very high vulnerability, while La Florida Association exhibited a high vulnerability. These results align with the geological threats identified in the area, such as flows, falls, and collapses. Therefore, it is important to take into account the sedimentary, geodynamic and morphodynamic characteristics in determining vulnerability and exposure. The study emphasizes the need to implement prevention and risk reduction measures, as well as proper planning and community participation to address the challenges in this high-risk area.
