This paper explains the procedure for generation of a landslide risk index map at national level in Cuba, using semi-quantitative model with ten indicator maps and cell size 90 × m. The was designed implemented spatial multi-criteria evaluation techniques GIS system. Each processed, analysed standardised according to its contribution hazard vulnerability. indicators were weighted direct, pairwise comparison rank-ordering weighting methods, weights combined obtain final map. results per physiographic region administrative units provincial municipal levels. Sierra Maestra mountain system found have largest concentration high values while Nipe–Cristal–Baracoa has highest absolute values, although they are more dispersed. obtained allow designing an appropriated mitigation plan link information hurricane early warning system, allowing also evacuation landslide-prone areas.
