One additional seismic scenario, corresponding to the 1985 Michoacán great earthquake was made to verify the 1D equivalent-linear (E-L) models to local measurements and identify possible site effect by surface waves in the Mexican Valley basin. In this scenario the response from two points within the NAICM site is compared to the available measurements at one station (TXSO) near the site. Furthermore, a zonation of the site was made deriving maps of some ground motion parameters representing the site-specific ground response of the NAICM site during that event. Within the quantified outputs, peak ground acceleration, response spectra, time histories are used for the compassion; in combination with criteria from the site natural periods, shear strains and strain indexes. The 1D E-L ground response during the 1985 earthquake is in agreement with the TXSO registers for the northwestern part from the NAICM, at spectral periods up to 2.3 seconds. Towards the south, the response varies, as the soil condition varies as well. The overall trend in amplification throughout the NAICM site is in agreement with the reported measurements throughout the Mexican Valley. This is valid for the measured site periods (T=1.6-2.9 seconds). Based on the response spectra validation and the overall response, it is found a reliable response from the 1D E-L models for this seismic scenario for periods up to 2.3 seconds. Towards larger periods the E-L response appears over-damped, due to the surface waves related to the basin effect, which cannot be captured by that method. To account for basin effect within seismic design it is recommended to incorporate a factor either to the design spectra or ground motion prediction equation for the Mexican Valley for periods larger than 2.3 seconds.
