Iran’s Capital City Is Being Devoured by Sinkholes

Sinkholes and fissures are opening up the earth around Tehran, Iran’s capital city. And they threaten people’s homes and the local infrastructure.

The ground is cracking open, thanks to a water crisis that has deepened as Tehran’s population has ballooned. The region is in the midst of a three-decade-long drought and ongoing desertification. The problem has been compounded as the city’s population has grown to close to 8.5 million.

Water pumped from underground aquifers has gotten saltier every year as the city has increasingly relied on these underground water sources as opposed to rainwater. At the same time, a great deal of the dwindling water supply gets diverted to thirsty and inefficient agriculture.

As a result, land in the area is physically slumping in on itself. The ground around Tehran, sitting 3,900 feet (1,200 meters) above sea level, has subsided an average of 8.6 inches (22 centimeters) per year based on satellite measurements.

All that subsidence has cracked buildings and water pipes, opened holes in the drying earth, and caused miles-long fissures. Residents fear their buildings collapsing, Nature reported. The airport, oil refinery, highways and railroads in the area are all threatened.
