MIAMI – A new study led by researchers at the University of Miami found that a lot of buildings in South Florida are sinking into the ground. This could mean that the ground is being worn away below the surface.
Between 2016 and 2023, the study looked at 35 buildings and found that they were sinking at rates ranging from 2 to 8 centimeters (about 1-3 inches). The most noticeable effects were seen in areas like Sunny Isles, Miami Beach, Bal Harbour, and Surfside.
Experts said they were able to come to their conclusions by looking at a huge number of satellite pictures that showed how the ground had moved over time.
The lead author of the study, Farzaneh Aziz Zanjani, said in a release, “It was surprising to find how many subsidence hotspots there are along the coast of South Florida.” “The study underscores the need for ongoing monitoring and a deeper understanding of the long-term implications for these structures.”
The land in South Florida is mostly made up of layers of limestone and sand, which can wear away over time due to natural and man-made causes.
The Florida Department of Environmental Protection says that limestone is a sedimentary rock that is mostly made up of calcium carbonate and was formed from the shells and bodies of sea creatures.
The whole Florida peninsula is made up of limestone, but other materials like clay, peat, and rocks can make the land less likely to sinkholes and shift.
Researchers paid extra attention to Surfside, which is about 5 miles north of Miami Beach and is where 98 people died when a 12-story condo building fell in June 2021.
Even though some people said that subsidence was one of the causes of the collapse, researchers didn’t find any strong proof that it was the case.
A full government review is not due out until 2025, but investigators have found that mistakes in the building’s construction around the pool are what caused it to collapse.
Researchers made it clear that the study’s results are not meant to scare people who own land, but rather to lead to more research and close monitoring.
“Our hope is that officials in Florida will recognize the value of continued research on this issue across the state and explore how this novel technology can benefit coastal residents.” A professor of geology at the Rosenstiel School at the University of Miami named Falk Amelung said.
After the study came out, one of the communities that the researchers looked at said in a statement, “The City of Sunny Isles Beach strictly adheres to these regulations, including compliance with the Florida Building Code and ongoing reinspection requirements.” We are still confident in the safety of our people because these steps work.
