The province of Santiago de Cuba now a day have a different hazard, vulnerability and risks conditions in front of the impact of geological processes and phenomena that influence on its social and economic development. This time is been made a review about the main topics of this issue from an actualized perspective, taking in consideration the recent research results. [ABSTRACT FROM AUTHOR]

The investigation was guided to establish a geologic zonación engineer of danger and risks for inundation in the territory of Sagua of Tánamo, by means of the analysis and interpretation of the main conditions and conditioning causes of the physical means that propitiate the development of this phenomenon, with the employment of the techniques of digital cartography and SIG. The adopted method, contrary to the methods of traditional works of cartography engineer - geologic and the making of projects SIG, outlines the solution of the problem starting from the conjugation of both, considering among the methods and technical of digital cartographic representation the informatización starting from the work with maps bases and overlapping of its layers. The inundation risk map of Sagua de Tánamo is shown. [ABSTRACT FROM AUTHOR]

Several methods for seismic risk calculation were analyzed in order to obtain the more adequate one in relation with real data and conditions, available for seismic risk determination in Bayamo city. The seismotectonic risk, which expresses the periodicity of occurrence in determined zone, is analyzed using the computer techniques and systems. [ABSTRACT FROM AUTHOR]
