Louisiana now recognizing sinkholes

Bayou Corne sinkhole

The state will now recognize sinkholes as threats after updating its hazard mitigation plan.

For the first time, the state will map salt domes and their surrounding 2-mile radius in each parish. Salt domes are pockets of salt-deep in the ground. They’re sometimes drilled out and used to store crude oil, natural gas, or other material. A failed salt dome cavern is blamed for a 29-acre sinkhole to form in bayou Corne in Assumption Parish in August 2012.

The plan also covers threats from floods, levee breaks and coastal erosion.
