Why are they so Dangerous?
Sinkholes can be extremely dangerous because when their is a sinkhole, the ground collapses and anything or anyone on that surface will get pulled down into the sinkhole. Sinkholes should be a concern to you, especially if you live in a karst area, sinkholes can happen anywhere. Sinkholes are measured by SqueeSAR, which can detect surface displacements down to a millimeter. This technology can identify developing sinkholes, and potentially save lives.
