The subject of landslides among the risks of geological origin has been widely studied in the world, which allows us to evaluate how this phenomenon is analysed in different geo-environmental conditions and consequently to establish a work programme for the analysis of this problem. The objective of this research is to evaluate the levels of landslide risks in the municipality of Mayarí, Holguín, based on the characterisation of the engineering-geological conditions of the terrain using existing and historical geographical information and data compiled through work with Geographical Information Systems (G.I.S.), obtaining maps of total danger and total vulnerability and, based on these, maps of landslide risks in the municipality. In addition, graphs and tables were obtained that allow for a better characterisation and understanding of the maps. The "Methodological guide for the study of danger, vulnerability and risk due to landslides" and the methodology for the evaluation of risks, taking into account in both cases the heuristic and geomorphological methods, were used to carry out the work.
