Mexico City is sinking up to 15 inches a year

The capital of Mexico, Mexico City is sinking by up to 15 inches each year. While this is only occurring in parts of Mexico City and not the entire city, it is quite concerning. To put that in comparison, Venice, the city in Italy famous for sinking, only sinks at a rate of half an inch each year, 1/30 the speed at which Mexico City is sinking. The city is sinking due to a large amount of its water coming from an aquifer underneath the city.
