Ground is Sinking Under Millions of Homes in Indian Cities: Study

A new study offers a serious warning for India’s rapidly expanding urban areas, presenting evidence that large parts of five megacities, including Delhi, Mumbai, Chennai, Kolkata and Bengaluru, are sinking due to the over-extraction of groundwater. This subsidence is causing uneven ground deformation, which in turn is putting thousands of buildings at growing risk of long-term structural damage.
