A part of the condo, which was constructed in 1981, was reduced to rubble as it collapsed in Surfside, a beachside town. At least one person is confirmed dead and nearly 100 people are missing, according to officials, while several of the injured have been pulled out from under debris.
The building had been sinking at a rate of about 2 millimetres a year in the 1990s, according to a study conducted by Shimon Wdowinski, a professor at Florida International University in 2020.
“I looked at it this morning and said, ‘Oh my god. We did detect that,’” Mr Wdowinski told USA Today following the news of the collapse.
Mr Wdowinski said the research focused on which parts of Miami were sinking to understand the areas of the city that can be impacted by sea-level rise and coastal flooding. He said sinking generally results in an impact on the building.
“We saw this building had some kind of unusual movement,” Mr Wdowinski said.
The study, which was published in 2020, collected data from 1993 to 1999 and found that most of the sinking occurred in areas with lower elevation, such as the western part of Miami. But the level of sinking at the Champlain towers was unusual.
Surfside Town Commissioner Eliana Salzhauer said: “This was not an act of God. This was not a natural disaster. Buildings don’t just fall.”
She told Miami TV network WPLG that the building was undergoing structural changes under a county-mandated 40-year recertification process. The changes involved electrical and structural inspections and the process was believed to be going smoothly, she said.
“I want to know why this happened,” Ms Salzhauer said. “That’s really the only question. … And can it happen again? Are any other of our buildings in town in jeopardy?”
It remains unclear what caused the collapse of the 40-year-old building. Fire rescue personnel worked through the night to find missing survivors in the rubble, which is said to be 30 feet (10 metres) high.
"These are very difficult times, and things are going to get more difficult as we move forward," Miami-Dade Police director Freddy Ramirez said, according to the Associated Press.
Fire rescuers said they detected banging noises from the rubble as they tried to trace more people with the help of sonar devices.
At least 35 people were pulled out from under the wreckage in the first hour of the rescue mission and 11 were found injured. Four people are receiving treatment in the hospital.
