Descripción
We present a model of shear wave velocity for the botanical garden of the Benemérita Universidad Autónoma de Puebla in Puebla City using ambient seismic noise recorded on a geotechnical scale array. We estimate phase velocity dispersion curves of Rayleigh waves, using the Modified Spatial Autocorrelation Method (MSPAC), between 1.5 and 7.1 Hz. Also, in each station the Horizontal-Vertical Spectral Ratio was calculated (HVSR). To obtain shear wave velocity profiles, congruent with the fundamental period of the site, we carry out a joint inversion between the HVSR and the phase velocity dispersion curves under the assumption that ambient seismic noise is a diffuse field. To improve the resolution of the velocity models, we recovered the Green's function by time domain cross-correlation of ambient seismic noise in a range of 5.3–12 Hz and calculated the travel times of the wave trains between pairs of …
