A study by the University of Miami found that nearly 35 high-rise condos and luxury hotels along a 12-mile stretch of South Florida’s coast, from Miami Beach to Sunny Isles Beach, are sinking or settling by 0.8 to 3.1 inches, with about half being less than 10 years old.

Causes include nearby construction, shifting limestone and sand layers, and tidal flows.

The findings highlight the need for monitoring building stability, especially in coastal areas.

The research follows concerns raised by the 2021 Surfside condo collapse, though that disaster was linked to concrete deterioration, NPR has reported.

Scientists plan further studies to assess uneven sinking and potential structural impacts.
