Scientists have discovered that parts of the New York City metropolitan area are sinking due to both human and natural factors, according to a recent study.
The research, conducted by scientists at NASA’s Jet Propulsion Laboratory and Rutgers University, used a remote sensing technique called interferometric synthetic aperture radar to analyze vertical ground motion in the metropolitan area from 2016 to 2023.
They found that the area declined about 1.6 millimeters per year, identifying neighborhoods and landmarks that are sinking faster than average.
For example, Runway 13/31 at LaGuardia Airport is sinking at a rate of approximately 3.7 millimeters per year, while Arthur Ashe Tennis Stadium is sinking at a rate of approximately 4.6 millimeters per year.
The team also identified areas that have risen such as East Williamsburg and Woodside.
These surfaces increased approximately 1.6 millimeters and 6.9 millimeters per year, respectively.
The cause of these elevations is still under investigation, but groundwater pumping and injection wells used to treat contaminated water may have played a role.
