Around the world, some of the biggest cities are slowly sinking beneath their own weight. Rapid development, groundwater removal, climate change, and unstable soil are causing streets, buildings, and entire neighborhoods to drop year after year. From historic capitals to modern megacities, these urban centers face growing risks from flooding and collapse.

Excessive groundwater use made the problem worse. Chinese authorities introduced strict water controls in the 1960s, but parts of the city still continue to slowly sink today.
