A Case Study of a Macro-Landslide in the High Mountain Areas of the Ecuadorian Andes: La Cría at the Azuay Province (Ecuador)

In this work, an evaluation of a macro-landslide that occurred in the La Cr & iacute;a community (Azuay province, Ecuador) is conducted. This macro-landslide covered an extensive area of approximately 443 hectares and affected a population that is mainly dedicated to agriculture. Historically, a landslide was already identified in the area in the 1973 geological map. However, there has recently been a significant increase in the speed of the landslide, causing damage to infrastructure and homes, and directly affecting 97 homes of various structural typologies. The study area is characterised by its geological instability, influenced by the presence of reservoirs for agriculture. In addition, the community of La Cr & iacute;a within the landslide has experienced considerable population growth. The study conducted combines the use of a landslide susceptibility map with a multicriteria analysis (which considers the interactions of geological, hydrological and land use) and a stability evaluation based on limit equilibrium methods. The results show that most of the territory assessed, approximately 55%, presents with a very high susceptibility to landslides, and reveal that the geology and the interactions between local geology and water resource management are needed to prevent and mitigate the risks associated with mass movements in the area.MDPI AGDepartamento de Ingeniería del TerrenoEscuela Técnica Superior de Ingeniería de Caminos, Canales y PuertosCentro de Investigación en Arquitectura, Patrimonio y Gestion para el desarrollo SostenibleRepositorio Institucional de la Universitat Politècnica de València Riunet20242024-12-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/228808reponame:RiuNet.
