US: Geologists from Florida have been to 30 sites and mapped about 50 sinkholes as they begin to plumb the depth of the state’s vulnerability to ground collapse. The Florida Geological Survey and Florida Department of Emergency Management are collaborating on the study.
In August, Florida received a $1.08 million federal grant for a three-year statewide study. The pilot project will end in May 2014.
“Essentially, what we’re looking for is all the variables that explain why a sinkhole occurs where it does,” said geologist Clint Kromhout. The result will be a detailed, multi-layered map that shows where sinkholes are most likely to form, but doesn’t predict where and when individual sinkholes will occur.
