Evaluación del riesgo por fenómenos de remoción en masa asociados con la distribución espacial y actividades productivas de la población del año 1987-2018, dentro de la vereda Vanguardia Alta

Abstract

The aim of this paper is to determine risk assessment by phenomena of massive removal (FRM) relate to spatial distribution and population productive tasks from 1987 to 2018 at an area of 54.59 Ha in Vanguardia Alta village. Thus, a descriptive-explanation methodology has been taken, altogether, surveys applications and community interaction let recognize socio-economic topics bound with them, further, phenomena and movements types were indetify using in sintu sampling. In the same way, adaptations, weights and interpolations for cuantitative values about massive movement risk allows the model adaptation.

42.4% of the subject area belongs to "Reserva Forestal Protectora Vanguardia Alta" and the remaining 58.7% properties as farms, housing, commercial premises, recreational, educational and conservation services (Bioparque los Ocarros ), the grades often goes from flat to sloping, furthermore, mostly massive removal phenomena identified possess a sandy- loam texture soil located at a distance greater than 500m from the population, being one reason why lower hazard handle, and combined with medium vulnerability shows low disaster risk levels.
