Mexico City, the capital of Mexico, was originally built by the Aztecs as Tenochtitlan on an island in Lake Texcoco. When the Spanish conquered the city in 1521, they decided to drain the lake rather than live with the water. Today, this decision has led to a major geological crisis: the city is sinking at an alarming rate of up to 20 inches per year. Because the city sits on a soft, clay-like lakebed, the heavy metropolitan structures and the constant extraction of groundwater from the aquifer beneath cause the soil to compress. This phenomenon, known as subsidence, has left many historic buildings, including the Metropolitan Cathedral, visibly tilted. The sinking creates massive challenges for infrastructure, leading to cracked pipes and vulnerable foundations. Despite being one of the most vibrant cultural and financial hubs in the Americas, Mexico City struggles to balance its ancient aquatic heritage with the engineering demands of a modern megacity of over 20 million people.
