NASA announced Friday that it may have found a way to predict sinkholes up to a month before they occur. The warning would be provided by interferometric synthetic aperture radar (iSAR), which could be placed on satellites or planes to scan areas prone to sinkholes.
iSAR scans the ground several times in several different wavelengths to put together interferograms, which can show small movements of the Earth such as the effect of flooding on riverbanks, the ripples of earthquakes and where the ground is sinking.
In just one state, Florida, there are 17 sinkholes a day on average costing 1.4 billion dollars in damage annually. (source: www.cnn.com... ).
Though researchers are optimistic that radar imagery could pinpoint subtle land deformations, those changes may not be an identifying factor for every sinkhole. That's why routine flyovers to obtain radar data may be more costly than they're worth
I tried to find the cause of that one. All I could find is that they found a lot of holes during construction, so I guess the area is prone to underground holes. Maybe there were a few more that they missed during construction, or they didn't check deep enough?
This is not any kind of guarantee, but any help possible is greatly needed when it comes to sinkholes
True, many are due to the failure of infrastructure, such as old busted water lines, but others just happen regardless, like at this Corvette Museum
