Mexico City’s Metro System Is Sinking Fast. Yours Could Be Next
Subsidence is causing parts of Mexico City to sink, and it’s happening at an uneven rate. That’s bad news for its sprawling public transportation system.
A metro system by its nature is a sprawling web of lines: Mexico City’s includes 140 miles of tracks running underground in subways, aboveground as you can see above, and on elevated platforms. “Trains can get derailed very easily if there is a slight change in the leveling of the railways,” says Manoochehr Shirzaei, an environmental security expert at Virginia Tech who studies subsidence but wasn’t involved in the new paper. Such efforts are increasingly urgent as climate change exacerbates droughts in many parts of the world, including Mexico City, putting ever more pressure on groundwater supplies.
