Subsidence, or the scientific term for the Earth's surface effectively sinking in on itself, is a serious issue. Not only does it present obvious infrastructure and safety dangers,, sinking land is also known to expedite the problem of already-rising coastlines. And by these researchers' estimates, the extreme sinking observed in China could mean that about a quarter of the nation's coastal regions are below sea level by the year 2120.
"Even a small portion of subsiding land in China," the researchers write, "could therefore translate into a substantial threat to urban life."are experiencing a concerning level of land sink, and in January, a satellite-based study revealed that US' major East Coast population centers are But while land sinking is an international problem, cities in Asia might be uniquely at risk. As Nicholls reportedly told, Asian cities are commonly constructed on river deltas, which are particularly susceptible to subsidence. The Indonesian capital city of Jakarta, for example, was built on a river delta and is sinking beneath sea level at a
