Study Reveals Dozens of South Florida High-Rises Are Sinking Faster Than Expected

Researchers found 35 buildings along the Miami-Dade coastline have sunk up to 3 inches since 2016, raising questions about long-term stability and safety.

The University of Miami study identified 35 high-rise buildings, including condos and hotels, sinking between 0.8 and 3.1 inches from 2016 to 2023.
The phenomenon, known as subsidence, is most pronounced in Sunny Isles Beach, with Miami Beach showing the least impact.
Factors contributing to the sinking include the weight of the buildings, vibrations from nearby construction, shifting sand layers, and potential effects of rising sea levels.
Local officials, including those in Sunny Isles Beach, have stated the buildings are structurally sound but are conducting reviews to reassure residents and address concerns.
Experts emphasize the need for continued monitoring, improved building practices, and further research into the geological and environmental factors causing the subsidence.
