subsidence

Buildings and water pipes are beginning to crack because of land subsidence.

To assess the risk to China's deltas, the researchers combined geological records, measurements of land subsidence, and data on human impacts.

“We were surprised because land subsidence is not like flooding or wildfires,” Nemati said, describing those climate-fueled disasters as much more visual and sudden.

The slant - caused by subsidence linked to mining - created the illusion that coins, if dropped inside, appeared to roll "uphill".

And they do not suggest massive subsidence or a cave-in of the mountain.
