Researchers at the University of Bonn with US colleagues show that the East Coast of the USA is slowly sinking into the sea.
The East Coast of the United States is threatened by more frequent flooding in the future. This is shown by a recent study by the Universities of Bonn, South Florida, and Rhode Island. According to this, the states of Virginia, North Carolina, and South Carolina are most at risk. Their coastal regions are being immersed by up to three millimeters per year – among other things, due to human intervention. The work is published in the journal ‘Scientific Reports’ by the Nature Publishing Group.
Cities such as Miami on the East Coast of the USA are being affected by flooding more and more frequently. The causes are often not hurricanes with devastating rainfall such as Katrina, or the recent hurricanes Harvey or Irma. On the contrary: flooding even occurs on sunny, relatively calm days. It causes damage to houses and roads and disrupts traffic, yet does not cost any people their lives. It is thus also known as ‘nuisance flooding’.
And this nuisance is set to occur much more frequently in the future. At least researchers from the Universities of Bonn, South Florida, and Rhode Island are convinced of this. The international team evaluated data from the East Coast of America, including GPS and satellite measurements. These show that large parts of the coastal region are slowly yet steadily sinking into the Atlantic Ocean.
