Description
Summary:Lifelines and infrastructure systems are among the most critical operational components of an urban environment to ensure a minimum level of post-earthquake economic and societal functionality following major seismic events. The overall performance of lifeline systems after the September 19, 2017 Mw 7.1 Central Mexico earthquake was generally positive. The most extensive impact was observed on the fresh water supply network within Mexico City (CDMX), which resulted in the temporary loss of water supply for nearly six million people, yet expedited repair work and temporary solutions limited severe interruption of daily operations and helped mitigate human suffering. The road, railroad and bridge networks were reported to have experienced very limited damage. Less than a dozen bridges indicated some level of damage in the areas affected by the earthquake. Only few selected rail stations within the public transportation system of Mexico City (metro) were temporarily closed for up to one month due to structural damage. The electricity network was reestablished to its full capacity within four days. Several case studies in the regions ranging from Mexico City to the earthquake epicenter (Puebla) are presented in this paper to provide an overview of engineering success stories as well as opportunities alike. •Lifeline and infrastructure damage due to the 2017 Central Mexico EQ documented and in general good performance of lifelines observed.•Utility damage among the most frequent, including temporary loss of electricity and water supply.•Very quick solutions and repair work observed.•Bridge damage in CDMX and surrounding areas modest, evacuation routes not needed.•Network and communication systems suffered limited damage, not described in this paper.
