Resumen:
Prediction of the ground shaking response requires data expressed in
terms of soil dynamic properties. Based on the analysis of surficial
geology, geotechnical borehole data, seismic refraction (V-S) and
microtremors (H/V) surveys, we have developed a qualitative evaluation
of local ground response to earthquakes in the Monterrey Metropolitan
Area (MMA), the main urban and economic hub in northern Mexico. The
results provide a detailed geotechnical model for the central zone of
the MMA. Although such information is not yet complete for the MMA
region, an initial approach has been developed in order to estimate the
distribution of damage associated with expected moderate earthquakes. An
empirical correlation is introduced to obtain V-S as a function of
standard penetration test blow counts (SPTN). According to the results,
the central-southern part of the study area might experience higher
amplifications of ground shaking produced by moderate seismicity because
the larger thicknesses of alluvial sediments are deposited there. The 2D
geotechnical model proposed would be very useful in making decisions
regarding planning or land use, deployment of protocols of rapid
response and for producing detailed microzonation maps for those zones
with similar geological features as the MMA in northeast Mexico.
