Mexico is frequently hit by moderate and strong hurricanes and earthquakes. There are some specific maps for seismic and aeolian design intensities through the whole country. They are based on different criteria. In the last years, wind turbines have been widely accepted in Mexico and it is expected to reach major diffusion in the next years. Several criteria have been explored to choose the best design intensity for both wind and seismic actions. In this work, two criteria to select the design intensity have been studied. The simplest criterion is the one based on a constant intensity in all the country, the second is based on an optimum design criterion. The aim of this study is to compare reliability indexes due to each one of the cases, for both wind and seismic hazards. To do that, a complete and detailed description of the seismic and aeolian hazards by mean of excedance rates curves is used. Several contour maps are displayed in order to show the variation of these indexes in all the country. Finally, design intensities related to different constant failure rates are shown. A discussion of the pros and cons of each design criterion is presented.
