Is Mexico City sinking into the ocean?
Scientists first noticed Mexico City was sinking in the early 1900s, at a rate of roughly 8 centimeters a year.Today, the upper clay of the city is already 17 percent compacted, and the authors say these changes are “almost fully irreversible.” Of course, not all parts of the city are sinking at the same rate.
What happened to the lake Mexico City was built on?
After the Spaniards built Mexico City on the ruins of the Aztec city they had destroyed, they conquered the lake waters. The Aztecs had kept floodwaters at bay through a network of dikes, levees and canals. The Spaniards ignored all that and just began to drain the water.

Why is Mexico City running out of water?

Is Mexico City sinking 2021?

Why is the ground beneath Mexico City subsiding?
As water extraction drove groundwater deeper underground, the 100-meter-thick, salty, clay-rich lake bed was left high and dry. Its very fine mineral grains have since been steadily repacking themselves more tightly, causing the ground to shrink and subside.
Why is Mexico City so crowded?
Thanks to poor urban planning (and rapid growth that made some forms of planning impossible), Mexico City suffers from extreme sprawling. This means there’s heavy traffic as people move from one side of the city to the other, as the rich travel to and from their gated communities, the poor to and from their barrios.
