This study presents dynamic site characterization measurements at 25 sites within the Mexico City Basin. The primary focus of the testing was along the western edge of the Mexico City Basin. At each site, active source Multi-channel Analysis of Surface Waves (MASW) arrays and passive source Microtremor Array Measurements (MAM) L-arrays and circular arrays were used to acquire dispersion data. Horizontal to Vertical Spectral Ratio (HVSR) data was collected to determine site periods at each location. These experimental dispersion data and site periods were fit using a joint inversion of Rayleigh and Love wave dispersion data and HVSR site period to produce shear wave profiles for each site. It was determined that the shear wave velocity for the lacustrine clay layers varies across the basin, generally getting softer toward the center of the basin’s lakebeds. From the site periods, it was determined that the seismic zonation of Mexico City should be reexamined in certain areas along the western edge and possibly updated due to variation between the current seismic zonation and the measured sites in this study.
