Ore body landslide risk assessment, Punta Gorda, Moa, Cuba
Keywords:
Landslides, cartography, laterites, risk analysis, Punta Gorda ore body.Abstract
Landslides occurring in Moa lateritic mines with weathering crusts are affecting mining activities. For that reason, the susceptibility of the area of Punta Gorda ore body to landslides was evaluated for a landslide risk assessment due to the instability of the slopes. By means of photointerpretation geomorphological criteria, the inventory reported 21 landslides having morphological characteristics, preferential and lithological directions where they occurred. The rotational movement is the prevailing typology. The soil susceptibility to fracture was classified into 4 categories: low, average, high and very high. 25 % of the total area under study has been classified to be very vulnerable. This indicates that the lateritic soils are highly prone to landslides.Downloads
