The Assumption Parish sinkhole, a massive opening in the earth that is believed to be the result of a collapsed salt dome used by petrochemical services company Texas Brine, underwent a sudden growth spurt around 5:30 p.m. Wednesday.
Parish officials were on hand to witness a process called a "slough-in," where the edge of the sinkhole collapses into the hole. Assumption Parish Office of Homeland Security and Emergency Preparedness director John Boudreaux took this video:

Gov. Bobby Jindal and other state and local officials met with Texas Brine representatives on March 13. The company responsible for a giant sinkhole in Assumption Parish is sending appraisers to some evacuated homes in Bayou Corne on Monday.
The Governor said company officials will also meet with the State Attorney General’s office on Monday. He said Texas Brine owes state and local governments 4 million dollars, combined, for costs incurred dealing with the disaster.
Environmental activist Erin Brockovich says Assumption Parish residents whose homes are threatened by a huge sinkhole should sue the owners of a failed salt dome cavern believed to have caused the sinkhole.
The Advocate reports that Brockovich told Bayou Corne residents at a meeting in Pierre Part that legal action is their only chance of relief.
About 350 people have been evacuated since early August, when the sinkhole appeared. It has kept growing since then.
The Louisiana Office of Conservation has modified orders requiring Texas Brine Co. LLC to assess the status of sediments under an 8.5-acre sinkhole in northern Assumption Parish, prompting the company to withdraw a lawsuit filed last month against the state.
A Houston-based company has asked a state court in Baton Rouge to permanently block the Louisiana conservation commissioner's order for new exploratory wells and other steps meant to monitor the effects of a huge sinkhole in Assumption Parish.
The Advocate reports that Texas Brine Co. LLC also challenges Commissioner James Welsh's declaration of an emergency, which let him order the steps without a hearing.
Officials say tremors recorded in Assumption Parish since late May could be why a brine cavern encased within the Napoleonville salt dome failed and caused a massive sinkhole.
Texas Brine Co. spokesman Sonny Cranch said Tuesday a tool used to measure the depth of the cavern bottomed out 1,300 feet higher than anticipated. Cranch said the presence of this material indicates the cavern failed.
Officials say an abandoned brine cavern in the Napoleonville salt dome has been successfully breached.
State Commissioner of Conservation James Welsh said Monday the investigatory well entered the cavern Saturday evening. Officials say they hope samples taken from inside the cavern will shed some light on the cause behind a massive sinkhole that erupted in Assumption Parish Aug. 3.
Officials say natural gas samples taken from inside the cavern will be tested for connections with gas bubbles that have been identified in other areas of the parish.
