GEOLOGICAL UPHEAVAL: Burp Event Recorded At The Giant Louisiana Sinkhole – Trees Slough-In Near Pad #3, Slight Odor Of Hydrocarbons Present! [LATEST FLYOVER & PUBLIC BRIEFING VIDEOS]

March 27, 2014 – LOUISIANA, UNITED STATES – According to the Assumption Parish Police Jury, at approximately 3:45pm on March 26, 2014, a burp and slough-in occurred at the giant Louisiana sinkhole.

Debris is present and floating on the sinkhole and trees near Pad #3 sloughed in. A slight odor of hydrocarbons is present in the Bayou Corne community.

As more information develops on the extent and repercussions of the event, it will be shared here.

Meanwhile, the Office of Conservation has provided the following update on response activity around Bayou Corne/Grand Bayou:

Sinkhole Activity Code 1 – indicating work is allowed on sinkhole and within containment berms. Seismic monitoring indicates low levels of subsurface activity near sinkhole/Oxy 3.

Air Monitoring/Sub-slab Sampling and Ventilation
– Conducting ventilation system inspections

ORW/CPT Wells
– Ending ORW 21 pump test (north of Sauce Piquante, west of Crawfish Stew)

– Continuing de-watering test on ORWs 4 (northwest of containment berm) and 14 (Oxy 9 well pad), 48 (north of containment berm) and OGRW 1 (Oxy Geismar 2 well pad)

– Continuing pump test on ORWs 1 and 32 (north of La 70, east of Gumbo St.)

– Flushing out ORW 39 (north of containment berm)

– Installing electrical equipment ORW 57 (southeast of Oxy 9 well pad)

– Depressurizing Oxy Geismar 3A (working from Oxy 9 well pad)

Containment/ Roads/ Sinkhole/Survey
– Continuing work on west end of south containment berm reroute, covering geotextile fabric with clay

According to Deborah Dupre of the Louisiana Sinkhole Examiner, the swamp monster sinkhole has established a pattern in the area: seismic activity occurs, the monster sinkhole burps up debris it had swallowed, a slough-in occurs, and the sinkhole grows accordingly.

It burps when air and gas from deep in the sinkhole bubbles up, causing not only debris, but also a hazardous oily substance to float to the top.

It has a “slough-in,” swallowing trees and land on its edge.

In June 2012, locals reported gas bubbles in Bayou Corne and Grand Bayou. By early August, 200 feet of ground had opened in the swamp. The Earth’s surface slid sideways up to 10 inches (26 centimeters) before it collapsed into the Bayou Corne sinkhole, according to a new study based on recordings of what happened when the hole formed.

Cathleen Jones, a radar scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. said about the report of the slide, “Usually at a sinkhole, we expect to see vertical movement at the surface, some sort of subsidence. This horizontal motion is actually a new indicator people should be aware of.”

Live Science reported last month:

The subtle surface changes revealed in the new study, published in the Dec. 13 issue of the journal Geology, could improve models of how the sinkhole formed, Jones said. “I think this can tell you something about the path between the cavern collapse, which is about a mile deep, and the surface,” she said. The sideways flow was like water slipping into a bathtub drain, Jones said. “The fact that the movement was toward a center point might tell you something about the geometry of the path that went down to the void,” she said. The subtle flow forms a pattern like a two-leafed clover, consistent with a cavern sidewall collapse as suspected by the USGS, Jones and NASA colleague Ronald Blom report.

The pit opened into a natural underground oil reservoir, releasing oil and toxic gases, such as methane and hydrogen sulfide throughout the hole and into the communities.

The disastrous hole has now grown to 26 acres and become a chemical lake. Officials had predicted it could grow as large as 30 football fields.

One of Texas Brine salt caverns that it leases from a salt dome company collapsed, causing the sinkhole.

That cavern had problems years ago. State officials knew that and quietly turned a blind eye to it, even when the problems prompted the company to abandon it.

Scientists now say that Texas Brine’s cavern was too close to the outer edge of the entire 1-mile by 3-mile Napoleonville Salt Dome salt dome housing it.

Texas Brine is one of seven companies storing oil and gas-related chemicals, including butane, in the salt dome.

A class-action lawsuit against mining companies Texas Brine and Occidental Chemical was filed in federal court in May 2013.

Residents were told to evacuate and began receiving weekly checks from Texas-Brine in the amount of $875 per week.

The sinkhole is still growing, gobbling hundred-year-old trees and threatening Highway 70 south of Baton Rouge and west of New Orleans.

When Jones first learned about the sinkhole in April 2013, she suspected NASA’s radar data would show little extra information, due to soggy ground in Louisiana’s swamps interfering with radar imaging. She was wrong.

“The signal was so big it overwhelmed all that noise [from the soil moisture],” Jones said. “When I looked at the data, I thought, ‘Wow, this is an enormous signature.’

“I couldn’t believe it,” she said. “The whole area was being pulled toward the sinkhole.”

The area has become a “national sacrifice zone” for the oil and gas industry.
