Soil conditions in Mexico City are described, and results are presented from special studies made since the earthquake, exploring in detail the soil conditions at the sites of strong-motion recording stations and at other sites of interest in and near the city. Results are also given of some analytical studies which examined the extent to which the observed differences in shaking intensities can be predicted using simple analyses of ground response, incorporating measured properties of the shear wave velocities of the soils. The study is part of a cooperative investigation being undertaken by investigators at the National Univ. of Mexico and the Univ. of California at Berkeley
