Fj. Chavezgarcia et J. Cuenca, SITE EFFECTS IN MEXICO-CITY URBAN ZONE - A COMPLEMENTARY STUDY, Soil dynamics and earthquake engineering, 15(2), 1996, pp. 141-146
Site effects are a major factor affecting seismic risk at Mexico City
conurbation and have been carefully studied. However, most of the stud
ies and instrumentation concentrate in Mexico City. We present an eval
uation of site effects in the counties of Estado de Mexico, to the Nor
th of Mexico City, that have been incorporated into Mexico City conurb
ation. We measured microtremors at 67 points and operated a temporal d
igital seismograph network. Our results allow us to extend the dominan
t period map of Mexico City to the heavily populated and industrialize
d counties of Estado de Mexico. Additionally, we propose a map of maxi
mum relative amplification. Both maps are consistent with local geolog
y, and could be useful for microzonation of this region.
