Resumen:

This paper summarizes some of the key findings and observations, following the September 19th, 2017 Mw 7.1 Puebla-Mexico City earthquake. The principal topics that are discussed in this paper are: (1) site effects in Mexico City for normal and subduction events, (2) ground subsidence, and its implication on soil-structure interaction and the observed damage, (3) vulnerability studies based on fragility curves, (4) topographic effects, and (5) seismic performance of underground structures. This paper revisits the characteristics of the event, the damage distribution across Mexico City and surrounding regions, the performance of buildings, lifelines, and other critical infrastructure in the city. The observed damage is analyzed considering site effects, seismic soil-structure interaction effects and the impact of regional subsidence, topographic and basin effects. Comparisons are made between the observed building damage patterns following the September 19th, 1985 and the 2017 earthquakes, and the differences are discussed. © 2019 Associazione Geotecnica Italiana, Rome, Italy.
