Studies say East Coast line will change sooner than expected

East Coast cities are the densely populated areas, economic hubs, infrastructures, and political epicenters in the U.S.A. And they are all facing subsidence. According to, many cities along the coastline of the Atlantic Coast are sinking at an alarming rate with some areas swamping faster than the global sea levels.

The researchers of Virginia Tech’s Earth Observation and Innovation Lab, associate professor Manoochehr Shirzael, and colleagues measured and reported that “We know to some extent that the land is sinking, and we highlight that sinking of the land is not an intangible threat. It affects you and I and everyone, it may be gradual, but the impacts are real,”

In the study, the results indicate that up to 2.1 million people living in these regions are sinking by 2 millimeters (0.08 inches) a year, with 867,000 properties located in these areas. Out of the 172 counties examined, seven to 43 are descending by around 5 millimeters (0.2 inches) a year which is more than at the global sea levels of 4 millimeters (0.16 inches) in a year.

According to the evaluation in the study, from the satellite images from the USGS, from the southern state, of Florida, to the northern state of Maine, coastline cities are all under threat of submersion and eventual disappearance. The lead author, Leonard Obenhen emphasized that “the problem is not just that the land is sinking,” and “the problem is that the hotspots of sinking land intersect directly with population and infrastructure hubs,” in the study.

The study shows through the vertical land motion that most of the high-density populated cities on the coastlines, route 95, route 1, route 13, and JFK International Airport will soon find themselves under water.
