GIANT SINKHOLE: A large ongoing disaster which has not been reported much

Tim Murphy at Mother Jones described the sinkhole at Bayou Corne as "the biggest ongoing disaster in the United States you haven't heard of."
One night in August 2012, after months of unexplained seismic activity and mysterious bubbling on the bayou, a sinkhole opened up on a plot of land leased by the petrochemical company Texas Brine, forcing an immediate evacuation of Bayou Corne's 350 residents—an exodus that still has no end in sight. Last week, Louisiana filed a lawsuit against the company and the principal landowner, Occidental Chemical Corporation, for damages stemming from the cavern collapse. Texas Brine's operation sits atop a three-mile-wide, mile-plus-deep salt deposit known as the Napoleonville Dome, which is sheathed by a layer of oil and natural gas, a common feature of the salt domes prevalent in Gulf Coast states. The company specializes in a process known as injection mining, and it had sunk a series of wells deep into the salt dome, flushing them out with high-pressure streams of freshwater and pumping the resulting saltwater to the surface. From there, the brine is piped and trucked to refineries along the Mississippi River and broken down into sodium hydroxide and chlorine for use in manufacturing everything from paper to medical supplies.
