FIU professor: Collapsed Surfside building showed signs of subsidence in ‘90s
The area where a building partially collapsed in Surfside, Fla. showed signs of land subsidence in the 1990s, according to space-based radar data analyzed by an FIU professor.
The 2020 study conducted by FIU Institute of Environment Professor Shimon Wdowinski identified the 12-story Champlain Towers South condominium as the one place on the east side of the barrier island where land subsidence was detected from 1993 to 1999. But land subsidence in and of itself likely would not cause a building’s collapse, according to Wdowinski, an expert in space geodesy, natural hazards and sea level rise.
“When we measure subsidence or when we see movement of the buildings, it’s worth checking why it happens,” Wdowinski said. “We cannot say what is the reason for that from the satellite images but we can say there was movement here.”
Western Miami Beach saw subsidence over larger areas but that was expected because homes there are built on reclaimed wetland. Areas where land is subsiding are more likely to experience more serious effects of sea level rise, according to the study.
n the 1990s, Miami Beach experienced subsidence at the rate of 1-3 millimeters per year, which could add up to a few inches of movement over a decade, Wdowinski said. It was significantly slower compared to other parts of the planet Wdowinski has studied. Mexico City, for example, is subsiding at a rate of 15 inches per year.
The researcher believes the same technology he used to detect land subsidence could be used to detect vulnerable buildings and help prevent future catastrophes.
The study was published in the journal Ocean & Coastal Management."
Maybe they can pin this in Jeb!

FIU...of collapsing Bridge infamy?
Looked at the Headline and thought it said “FU Professor”...
“...all other ground is sinking sand.”
Like always there will be a critical mass of errors and natural events. RIP you 99.
Probably used chinese rebar and materials.
Will blame it on DeSantis
Call Greta, this is clearly global warming!
If this building was literally sinking since the early 90s it took this long for it to collapse that makes no sense. Our house foundation also sinks from time to time, been like that since day 1, its the soil..tried putting beams, etc doesnt seem to ever do the trick so every few years or so we start to see cracks here and there on the walls and at night and when it rains its harder to open for instance the bathroom door, but the house wont collapse..
Can check it out via WayBack machine:
Collapsed Miami condo had been sinking into Earth as early as the 1990s, researchers say

Indeed!
One wonders if that cheap lousy quality concrete from China was used in the construction, ala Oakland Bay bridge.
The land isn’t sinking...the sea level is rising. Global Climate Catastrophe! Stop eating meat!
I think subsidence is the reason for a lot (if not most) of the “rising sea level” stories.
Did they build it on sand?
A Florida sinkhole? Who knows. Very sad - hopefully many will be recovered. I think I would be a little nervous if I lived in a condo near that one until we know what happened.
So, in plainer English, using drilled and poured sticks of concrete to stand on bedrock is not as good as building on bedrock itself. Good to know.
