Das U-Bahn-System von Mexiko-Stadt verfällt schnell. Ihr könnte der Nächste sein

Mexico City has the second largest subway system after New York City’s. But the weight of urbanization is literally causing the city to sink up to 20 inches a year, unleashing havoc on the metro.

Why is Mexico City sinking? Subsidence, experts say, which is caused by the removal of resources from the ground, like mining and fracking. Subsidence may have also contributed to a 2021 overpass collapse that killed 26 and injured nearly 100 in the city.

It’s not just Mexico City. Earlier this year, scientists found that the East Coast’s infrastructure is in serious trouble due to subsidence—calculating that 29,000 square miles of the Atlantic Coast are exposed to sinking of up to 0.08 inches a year. Be it in the US, Jakarta, or Mexico City, people have to stop over-extracting groundwater to slow subsidence.
