Collapsed Miami condo had been sinking into Earth as early as the 1990s, researchers say

A Florida high-rise that collapsed early Thursday was determined to be sinking a year ago, according to a researcher at Florida International University.

The building, which was constructed in 1981, has been sinking at an alarming rate since the 1990s, according to a study in 2020 by Shimon Wdowinski, a professor in the Department of Earth and Environment.
