![]() Most of the subsidence occurred in the western side of the city. We found that most of the city of Miami Beach is stable except for several pockets that show subsidence at a rate of 1-3 millimeters per year. ![]() The study was to also assist with the development and implementation of more efficient flood emergency response and recovery plans. The study was designed to provide local advisory organizations, such as the Southeast Florida Regional Climate Change Compact, with important information for improving flood hazard assessments. Our 2020 study of land subsidence and coastal flooding hazards in Miami Beach used Interferometric Synthetic Aperture Radar, or InSAR, data from the 1990s. Because rising sea levels and or land subsidence can increase coastal flooding, we wanted to understand how much of the threat is coming from the rising sea levels and how much from subsiding land. Rising sea levels introduce a major threat to these communities. We also studied Norfolk, Va., which has similar flooding occurrences. We conducted this study because we were concerned about increased flooding in South Florida, especially in Miami Beach and in Surfside. He also holds a master's degree in geology from Hebrew University. He holds a master’s degree in engineering sciences and a Ph.D. Below he addresses key questions about subsidence and his research in the wake of the tragic building collapse in Surfside, Fla.Īn expert in space geodesy, natural hazards and sea level rise Wdowinski is part of the FIU Institute of Environment and the Department of Earth and Environment. FIU geophysics professor Shimon Wdowinski discusses a 2020 study where he found land subsidence in Miami Beach and in Norfolk, Va.
