Tracking Developments At The Giant Louisiana Sinkhole - New Cracks Observed And Dozens Of Trees Lost As Sinkhole Swallows Up More Land!
March 27, 2013 - UNITED STATES - About 25 trees fell into the Assumption Parish sinkhole and a new crack formed Monday night in a earthen well pad south of the lake-like slurry hole, state regulators said.
Experts working for the state Office of Conservation believe the collapse and cracked well pad are linked to now-calmed seismic events from late last week, officials said in a statement Tuesday.
Because of that connection, agency officials said the discovery did not halt work around the sinkhole and the area remains in emergency officials’ lowest “alert” status. Parish officials also estimated Tuesday that the edge collapse, or slough-in, probably bit off a quarter-acre from the formerly 13-acre sinkhole’s southeastern edge. More firm measurements are pending.
Sinkhole swallows more trees
John Boudreaux, director of the parish Office of Homeland Security and Emergency Preparedness, updated other activities in the sinkhole response Tuesday:
Data gathering for a critical three-dimensional seismic survey of the subsurface under the sinkhole ended Sunday and equipment is being collected. Results are due April 21.
Crews moved in a specialized drilling rig, called a snubbing unit, on Tuesday that can handle high pressures so they can begin clearing out blockages in a key access well to the failed Texas Brine cavern.
Early on Friday, experts detected an uptick in “very long period” tremors, a type of stretched-out seismic event, that have been linked to fluid and gas movement underground.
The tremors were detected under the sinkhole and around the failed Texas Brine cavern.
1:25 p.m. Slough-In Occurance/Advisory from the Office of Conservation
The Office of Conservation, in consultation with Assumption Parish Incident Command, is advising the public that a slough-in occurred last night along the southeastern side of the sinkhole – approximately 25 trees fell into the sinkhole along the southeastern side and a new crack, running parallel to the sinkhole edge, was observed on the Oxy 3 well pad access ramp to the sinkhole.
She brought tears to my eyes today, could feel her pain. I would feel the same anguish if my home town was being destroyed.

Rainbaue is a good friend of mine and I talk to her everyday. Some of the info I get comes from her. She is a really sweet woman.

Assumption Parish Police Jury
The Office of Conservation, in consultation with Assumption Parish Incident Command, is advising the public that the Oxy 3/sinkhole monitoring alert status has been raised to Code 2 – requiring all work directly in and over the sinkhole to cease until further notice. Seismic monitoring has detected elevated subsurface activity in the area around the sinkhole and Oxy 3 area indicative of fluid and gas movement below the sinkhole, and a further slough-in was observed along the southeastern side of the sinkhole this morning, with the access ramp from the Oxy 3 well pad to the sinkhole having sloughed in, along with several trees on either side of the ramp. The seismic activity is limited to the Oxy 3/sinkhole area, showing no indication of impact to the Oxy 1 area. Monitoring is constantly ongoing in the area and Conservation will continue to advise the public of significant changes in subsurface conditions
