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."
FWIW, this reads to me like FIU is attempting to damage control for someone or something.
A house built on sand?
That's the direction it's going. There will be evacuations.
This is on the building inspectors. It will fall on city and county inspectors. This is not a state issue.
All the non stop Highrise building close by in that once quiet area probably crack the
foundation of this 1981 building .
They use lots of dynamite to reach the bed rock .
The Former mayor who was rescued last nite stated he
notified people about the cracked cement decking over the parking areas .
Water and especially sea water just needs a few good cracks to destroy .
It was a FIU PR thing .
Research it .
At least he's got chapter 7 protection. The HOA members can be sued individually. It's a thankless position and in this case one with a potential legal liability.
The building had a pile foundation To fail, the friction piles had to move. To move indicates they were not long enough
No! Florida sand is racist! DeSantis’ fault. The occupants of the building “Likely” voted for DeSantis. On a local newscast in 3...2...1...
In Miami, the probably is no bed rock.
Also, take a look at photos of Liberty Island and Ellis Island in New York harbor. Both sit barely above the water level, and photos taken of them in the late 1800s and early 1900s look exactly the same. The water hasn’t risen one inch.
They’re lying.
Someone has some splaining to do! Paid off building inspector?
Trumps fault DeSantis is just a piker compared to Trump!
There is a lot of limestone karst under Florida. I am no geologist but from what I’ve read, excessive groundwater pumping can lead to increased limestone erosion and sinkhole formation.
Someone has some splaining to do! Paid off building inspector?
“One wonders if that cheap lousy quality concrete from China was used in the construction, ala Oakland Bay bridge.”
Building construction was in the late 70’s so probably not.
More likely inferior mafia concrete.
It is too early to even make a guess on the cause. It was noted on one news broadcast that work was being done on the roof area and a new building was going up across the street from the condo.
Perhaps in the end it will just be a 12story building build on sand.
On Guam it is called “Earthquake Settling” it makes the drains clog because after several years they don’t have enough slope. We had to have the main sewer line re-plumbed when we lived there.
Smells like FBI disinformation.
