Erosion, Scour, and Mitigation

This paper investigates the seismic vulnerability of Mexico City, focusing on the impact of significant earthquakes, particularly those of 1985, 2017, and 2022. This analysis explores Mexico City’s geological challenges, including its location on a seismic lakebed, the effects of historical land drainage, and the amplification of seismic waves due to the land make-up. Among the earthquakes mentioned, the earthquake of 1985 was significant, serving as a wake-up call, leading to stricter building regulations and innovations in seismic-resistant architecture. Notably, the Torre Mayor, an earthquake-resistant building completed in 2003, exemplifies the success of advanced engineering in protecting structures from seismic hazards. In the entirety of its aim, the study highlights the city’s ongoing struggle with geological instability and the resilience of its infrastructure.
