28 US cities, including New York, Chicago and others are sinking, satellite study reveals

A recent satellite survey reveals that several major US cities are sinking. Cities like New York, Chicago, and Houston are experiencing land subsidence. The sinking rate varies between 2 to 10 millimetres annually. Groundwater loss and urbanisation contribute to this issue. This subsidence poses a threat to infrastructure and public safety. Experts recommend increased monitoring and stricter groundwater controls.
