GAYTAN RODRIGUEZ, Rodolfo et al. Urban morphology, structural damage, seismicity and accelerometric network of the City of Morelia. Ing. sísm [online]. 2022, n.spe108, pp.1-22.  Epub 10-Mar-2023. ISSN 0185-092X.  https://doi.org/10.18867/ris.108.599.

This paper describes the effects of some seismic motions in buildings of the city of Morelia, Michoacan, the urban morphology, soil characteristics, local seismic faults and the evolution of seismic design parameters proposed in local regulations. The importance of the Nicolaita Seismic Network, composed of 10 accelerometric stations, in recording the seismic movements to mitigate the seismic risk is pointed out. Currently, the recorded accelerograms have shown significant differences in the ground motion that must be considered when conducting a seismic hazard assessment. The paper also presents some recorded accelerograms and response spectra. The objective of this manuscript is to show that, according to the seismic history and the damage caused by past seismic events, the city of Morelia is a site prone to destructive earthquakes, which makes it essential the seismic network.

Palabras llave : accelerometric network; response spectra; dynamic amplification; seismic zonation; seismic design.
