Miami’s barrier islands are home to many luxury high-rises and, according to a study recently published in Earth and Space Science, about three dozen are sinking.

The collapse of the skyscrapers it amounted to 2-8 centimeters in a multi-year period from 2016 to 2023, according to the researchers.

High-rises expect to see “up to several tens of centimeters” of settlement “during and immediately after construction,” the University of Miami’s Rosenstiel School said in a post Friday on its website.

Builders built a “majority” of the affected condos and hotels after 2014, according to the study.

“We found that subsidence in most skyscrapers slows over time, but in some cases, it continues at a steady rate. This suggests that subsidence could persist for an extended period,” said lead author Falk Amelung.

The study authors had a few theories about what was behind the collapse, based on their research.

The subsidence “is primarily due to the gradual reconfiguration of sand grains into a denser packing within sandy layers interbedded with limestone” in the area, according to the study.

According to the study, the researchers hypothesized a link between construction-related vibrations or groundwater flow and the subsidence. Other things like daily tidal flow and stormwater injection could also have accounted for the phenomenon.

“The discovery of the extent of subsidence hotspots along the South Florida coast was unexpected. The study underscores the need for continued monitoring and a deeper understanding of the long-term implications of these structures,” said lead author Farzaneh Aziz Zanjani.
