Starting to think maybe they should drop an Alka-Seltzer down there

Serious reflux going on 

Enough earth flowed into the formerly plugged and abandoned cavern to squeeze the brine inside the cavern and raise its pressure so that a “frack out” of the cavern occurred, extending to the surface.

Hecox said a frack out happens when hydraulic pressure is raised enough to cause cracks that serve as channels to release the pressure.

The frack out brought up brine, oil and natural gas from surrounding natural formations along the salt dome’s edge to the overlying water aquifer and to the surface.

The movement of the compacted earth into the cavern created instability that led to the sinkhole, he said.
