BAYOU CORNE, LA (WAFB) -

More information will be given Tuesday about current efforts to contain the giant sinkhole in south Louisiana.

Texas Brine and Assumption Parish officials will hold an informational meeting at 5:30 p.m. to bring the community up to speed on the latest developments.

The focus will be on those vent wells siphoning gas from beneath the ground.

The meeting will be held at the command center in Bayou Corne.

History of the Sinkhole

The sinkhole opened up in August 2012 and was roughly 1/24 of the size it is now. The sinkhole formed when an underground salt cavern collapsed.

In the past, seismic activity is reported, then the sinkhole burps up debris and then a slough-in happens. Burps occur when air and gas from deep in the sinkhole bubbles up. It can cause debris and an oily substance to float to the top. A slough-in is when the sinkhole swallows trees and land that is on the edge of the sinkhole.

Berms were placed around the sinkhole shortly after it opened up to keep the oily, debris filled water contained to the sinkhole area so it would not contaminate the area bayous.

It has more than a year since hundreds living near the giant sinkhole were forced from their homes.

Bubbles were spotted in Bayou Corne and Grand Bayou in June 2012. Two months later, the ground opened up and left what is now a 24-acre sinkhole. Residents were evacuated and the most affected residents began receiving weekly checks from Texas-Brine in the amount of $875 per week. Texas Brine owns the salt cavern that collapsed, causing the sinkhole.

On August 2, Gov. Bobby Jindal and Attorney General Buddy Caldwell announced the state will be suing Texas Brine for environmental damages caused by the failed Texas Brine cavern.

Parish and Texas Brine officials agree the situation is far from over. 3D seismic surveys show the sinkhole itself it beginning to slow and stabilize, but the recovery is focused on another danger; natural gas gathering underneath a nearby aquifer.
