A study by UM scientists and collaborators shows 35 buildings on the Miami Beach to Sunny Isles Beach coastline are experiencing subsidence, likely due to load induced, prolonged creep deformation of sandy layers within the limestone, affected by vibration from construction activities.
The team used a satellite-based remote sensing technique known as Interferometric Synthetic Aperture Radar to measure ground surface deformation. They found that subsidence can persist for many years. “Establishing a public database…would enable residents, housing associations, and authorities to monitor their buildings for signs of subsidence, inspect for cracks, and take proactive measures,” says Antonio Nanni.
