South Florida's beachfront buildings found to be sinking faster than expected
A team of mechanical, architectural and environmental engineers, geoscientists, and geoinformation specialists affiliated with several institutions in the U.S. and Germany has found that many of the tall, heavy buildings along the coast of South Florida are sinking into the ground much faster than was expected.
In their study published in the journal Earth and Space Science, the group compared satellite images over several years to learn more about ongoing subsidence along multiple beachfront.

In this new study, the researchers noted that the many tall buildings along many parts of the coast in South Florida appeared to be extremely heavy. They wondered if adding so much weight might be causing the ground beneath them to sink.
To find out, the researchers obtained precise satellite imagery for several of the most popular beaches in South Florida and compared 35 buildings standing on them over time. Modern satellite imagery is so precise it can detect changes in altitude of just a few centimeters. The researchers found that every one of the buildings they measured was sinking, ranging from 2 to 8 cm over the years 2016 to 2023, and that most of them were sinking faster than expected.
