A
recent University of Miami study found that nearly three dozen buildings along South Florida's coast are sinking at alarming rates. The affected structures include luxury properties like Four Seasons Residences at the Surf Club and two Trump towers. However, experts say there's no cause for alarm as these buildings were designed to withstand subsidence.

    The study, which analyzed satellite images from 2016 to 2023, found that buildings in Miami Beach, Sunny Isles Beach, Surfside, and Bal Harbour are experiencing subsidence ranging from 2-8 centimeters. The most significant effects were observed in Sunny Isles Beach. Researchers used reference points like building balconies and air conditioning units to measure the shifts.

    While differential settlement can cause damage, the study found little evidence of this phenomenon. Instead, researchers suggest that ongoing monitoring and a deeper understanding of long-term implications are needed. Buildings along the coast in Broward and Palm Beach counties may also be experiencing subsidence.

    Experts point to several factors contributing to the sinking buildings, including groundwater flow from underground construction and the region's geologic makeup. The shifting of quartz sands within limestone layers, triggered by building weight and vibrations during construction, is likely a major contributor. Daily tidal flows and the cracking of limestone beneath the surface may also influence ongoing subsidence.

    Interestingly, the study found that the collapse of Champlain Towers South in Surfside was not caused by settlement. No displacement signals were detected prior to the tragedy, despite strong vibrations from nearby construction. The study suggests that a more nuanced understanding of the complex factors at play is necessary to mitigate future risks.
