NY It is sinking every second; This was confirmed by a new study. In the last 20 years, the sea rose 4.4 millimeters per year in Manhattan and this, in the future, could cause serious effects at socioeconomic levels.
He studypublished in Science Advances by researchers from NASA’s Jet Propulsion Laboratory and the Department of Earth and Planetary Sciences at Rutgers University, maintains that there are neighborhoods that would be more affected than others. Queens would be the most affected sector.
“If you are an average citizen in a coastal city I think it is important that you understand what the vertical movement component of the land does and how it can change the susceptibility to flooding, even from one neighborhood to another,” he warned. Brett Buzzangalead author of the study.
“More damage can be caused if sea level is higher and land is lower at the same time,” he added.
The novelty of the research has to do with the idea of having discovered “in unprecedented detail” the differences in the region and that “some places in New York may sink faster than others.”
“That may cause more flooding in some places“Buzzanga said, and warned:”This is going to be the same in any city.“.

In closing, Buzzanga said he and his group will soon use an updated version of their algorithm to make displacement data (with information on land subsidence and rise) available across North America.
This, according to the specialist, will make it possible to inform the risk of flooding and improve urban planning. “Every city in the world would benefit from such a refined analysis of city-wide vertical ground motion.“said the Rhode University oceanography professor, Steven D’Hondtal Washington Post.
Why is New York sinking?
While the land can sink for a variety of reasons, much of New York City does so primarily because the retreat of glaciers from the last Ice Age.

As the Post explains, the ice sheets weighed down the land and caused the crust to stretch and sink beneath areas such as the northeastern United States.
“New York City, however, was on the periphery of the sunken zone and bulged upward. As the ice sheets began to retreat, the land began to slowly level out and the sagging areas began to rise while The bulging areas began to sink,” specifies the American media.
Human activity can also contribute to subsidencesince very heavy solid constructions appear on some sensitive terrains.

The airport LaGuardia and the stadium Arthur Ashe of the US Open, for example, “they are going to compress much faster than something built on more solid ground.”
The tennis stadium, aware of this problem, was recently renovated with a special lightweight roof to reduce subsidence.
