Dear MEL Topic Readers,
New York City is sinking due to its million-plus buildings, study says
Jakarta, the capital of Indonesia, is located on the northwest coast of Java Island and is built on a low-lying plain intersected by 13 rivers. The city is sinking due to excessive groundwater extraction, soil compaction, and the weight of the buildings and infrastructure. So, the country is moving its capital to a new site on the east coast of the island of Borneo. Surprisingly, dozens of the world’s most populous coastal cities are sinking faster than sea level rising, too. Using a combination of computer modeling, satellite measurements, and GPS data, a recent study found that New York is sinking up to four millimeters a year. Researchers estimated that the total weight of all the skyscrapers and tall buildings is over 760 billion kilograms, nearly the same weight as 1.9 million fully-loaded B747s. Though the rate of subsidence is not as severe as the one in Venice, Italy, where the ground surface submerges in the famous canals from time to time, Big Apple is going to have more floods when it is hit by heavy rainfalls and hurricanes. What about other mega coastal cities like Hong Kong and Bangkok?
Enjoy reading and learning about the impacts of subsidence on mage coastal cities.
