A study done by geologists determined that the New York CityUSA, It’s sinking by the weight of its skyscrapers. As reported, the number of buildings aggravates the threat of flood that represents for the metropolis the rise in sea level.
“A deeply concentrated population of 8.4 million people faces varying degrees of danger from flooding in New York City”indicated the researchers in the study published in the journal Earth’s Future, in which the artificial and natural causes behind the collapse were analyzed.
The data provided indicates a problem for the inhabitants since the sea level has been rising at twice the global rate, and it is expected to rise between 20 and 76 centimeters between now and 2050.
In addition, scientists are forecasting more frequent and extreme precipitation, such as hurricanes, due to the man-made climate crisis.
New York in danger due to the weight of its buildings
The research aims to demonstrate how high-rise buildings in coastal, riverine or lake areas could contribute to future flood risk, and that steps should be taken to mitigate potential hazardous effects.
What is the soil like in New York?
The geology of the surface, in this case, is a complex glacial terrain that the study authors say includes sediments, sand, clay deposits, glacial moraines, washing and tillagebeach deposits and rock outcrops.
The acceleration of urbanization pushes down the set of said materials. And while many of the larger buildings are set on solid bedrock, such as shale, there is a mix of other sands and clays that it was built on that increases this subsidence.
“The cumulative pressure applied to the ground by large buildings contributes to subsidence not only because of the initial primary settlement caused by the soil compression and void space reductionbut also for a possible secondary settlement caused by creep in clay-rich layers that can continue indefinitely”, explain the professionals.
