GIRALDO-RAMIREZ, Wilmer Enrique  and  ARISTIZABAL-ARBOLEDA, María Fernanda. Technical analysis on the causes of the mass movement occurred in "Las Nieves" Quarry, city of Copacabana. Bol. cienc. tierra [online]. 2020, n.48, pp.12-22.  Epub Feb 01, 2022. ISSN 0120-3630.  https://doi.org/10.15446/rbct.n48.87484.

On October 26, 2016, a large-scale mass movement occurred surrounding the Medellín-Bogotá highway, near the municipality of Copacabana. This paper investigates the physical and legal conditions of the place where the landslide occurred, and thus, to corroborate the causes, the possibility of avoiding or preventing the phenomenon and the influence of anthropic activities in the sector. To determine the susceptibility to mass movements and verify the physical conditions, it was carried out by means of geological mapping, geomorphology and interpretation of satellite images. The legal and bibliographic review was consulted in the reports of the event, the PBOT of the municipality of Copacabana and the mining file of the Cantera Las Nieves. The area was found to be highly susceptible to mass movements, and exploitation in the Cantera Las Nieves triggered the landslide, which could be avoided. Similar phenomena could occur in the near future in the area.

Keywords : mass movement; Medellín-Bogotá highway; Copacabana; Cantera Las Nieves.
