SACASAS LEON, Carlos. Hazard of hurricanes in Cuba with the use of a GIS. RIHA [online]. 2013, vol.34, n.3, pp. 95-104. ISSN 1680-0338.

Statistical treatment and interpolation procedures applied to historical databases of tropical hurricanes occurring since 1851 within the Atlantic Basin are presented. Indices caracterizing tropical hurricanes threat over Cuba are defined and calculated. They are used to design a Geographic Information System (GIS) project in order to evaluate the threat, which is useful in Territorial, Environmental and Risk Planning studies. It is possible to manage this historical information with these calculated indices by evaluating their spatial behavior. Several interactive maps are introduced: trajectories, probability of affectation, wind average and maximum velocities, trajectories azimuth, month of most frequent occurrence, average hourly duration of affectation and the threat index. Cartographic information used allows representation on a scale of 1:250 000.
