Vulnerability to earthquakes is the most important. The city itself was built on the dessicated remains of Lake Texcoco, thus the underground is prone to "soil liquefaction" during strong earthquakes.
Also, water table depletion poses as a problem; as underground aquifers are over-exploited, sinking occurs. Some areas of the city sink by a couple of inches each year, resulting in cracking streets and sidewalks and from time to time, buildings that have to be evacuated due to unstable foundations.
yes it was origanly built on a lake

The Lake Texcoco was a lake on which the Aztecs built a city called Tenochtitlan. The Spaniards later built Mexico City on Tenochtitlan, which is now the present day capital of Mexico. The lake is now completely drained.

The city of Tenochtitlan
It was originally built by the Aztecs in 1325 on an island of Lake Texcoco.
The Aztec capital city, Tenochtitlan, was built on an island in Lake Texcoco in the Valley of Mexico. The city was connected to the mainland by causeways and canals.
The Aztecs built their capital city, Tenochtitlan, on two islands in Lake Texcoco, located in the Valley of Mexico. Tenochtitlan would eventually become the vibrant city that we now know as Mexico City.
Right. It was baptized as Mexico-Tenochtitlan and was founded on March 13, 1325.
The capital of the Aztecs, Tenochtitlan, was built in (modern-day) central Mexico on Lake Texcoco. Mexico City sits there today.
The Aztecs capital city, Tenochititan, was built over Texcoco Lake.
