摘要: A first microzonation map of seismic site class distribution in Monterrey Metropolitan area is presented. This was prepared using borehole information, seismic refraction profiling and surficial geology. According to geotechnical categories proposed by RodriguezMarek et al. (2001) NEHRP soil classification (VS30), C, C1-C2 sites classes are located to the south central study area. In the northwest zone, B classes are dominant. Lowest S-wave velocity (average 268 m/s) correspond silts, whereas highest velocities (average 2311 related Cretaceous limestones. Maximum thicknesses (16 20 m) soft sediments C-C2 are located at center area being correlated two paleo-channels. This provides an initial attempt understand and characterize
