The city of Santiago de Cuba is one of the most affected in the country by seismic events, due to its proximity to the Bartlett-Cayman seismogenic zone, however there are few instrumental records of strong events (M=6), thus it is necessary for the site effects analysis using various techniques that consider the environmental vibration as the Nakamura method. 104 points located mainly in regions bordering the bay of Santiago de Cuba are analyzed in sedimentary deposits. With the application of this technique, the fundamental frequencies and soil amplification coefficients are obtained, from the spectral ratio of the horizontal and vertical components (H/V) of ground motion records in these areas. Is performed an analysis of the amplifying factors regarding to the lithology.

The use of more refined models and computational techniques for seismic hazard evaluation and the availability of more data related to seismic events have allowed the updating of national seismic hazard studies. This paper summarizes the new methodology used to estimate the expected seismic intensities for design and construction of earthquake resistant structures in the country. Seismic intensities are obtained for different return periods and spectral ordinates, for the different heights of buildings. This data is useful in establishing design values in the new national building code NSR-10 and for the development of seismic microzonation studies. [ABSTRACT FROM AUTHOR]
