    Residents angry as Assumption sinkhole continues collapsing

    ...
    Geophyisicists now say the western side of one of the brine caverns is collapsing, filling in from deep in the Earth, causing the sinkhole at the surface to expand and contract.
    ...
    The secretary of the Louisiana Department of Natural Resources flat-out testified at the same hearing, ?The cavern collapse led to the sinkhole and created a path for the natural gas to come to the surface.?
    ...
    ?The sinkhole is constantly changing. It changes every time we go out there. Not just on the surface, but in the sub-surface,? said Gary Hecox, a hydrogeologist with CB&I, formerly the Shaw Group, who is a consultant for the state about how to best handle the sinkhole.

    He said it's uncharted territory.

    ?The cavern was 3,400 feet deep, which is deeper than any known cavern failure impacting the surface in the international record,? Hecox said.

    Nowhere in the world has a brine cavern this large collapsed, and Hecox said the data shows it's not finished yet.
    ...
    As photos from the Louisiana Environmental Action Network show, when the sinkhole first appeared, it was just 400 feet in diameter. As of mid-February, it had swallowed nine acres.

    Scientists say the worst-case scenario is it could swallow 40 acres.

          There's been quite a bit of news about this situation recently :

          More evidence of stresses on evacuees (Also see the video at the link Pathfinder posted here.):

          ?There?s no other answer. If God doesn?t help us, who will?? she said as tears filled her eyes.

          Gaudet was one of about 40 people who gathered at a special service at St. Jules on Feb. 22 to pray for those affected by the Bayou Corne sinkhole. Some were evacuees, others just came to offer support.

          ?I?m here to support these people. I don?t know any of the evacuees personally,? said Patsy Breaux, secretary for the church...

          Then the Advocate reports that the cavern described in the Sandia article (Oxy1/Hooker6) is the focus of more concerns about preparedness.

          New seismic surveys suggest a second Texas Brine Co. LLC cavern is closer to the Napoleonville Dome?s outer face than previously thought, leading the Assumption Parish sheriff to call Friday for the need to plan for emergence of a second sinkhole in the Bayou Corne area, however unlikely the possibility may be...
          Besides being closer to the salt dome than estimated, it might have an antiquated design - though this article might be specific to the geology of Kansas salt formations:

          Then over the weekend, Erin Brockovich addressed the Bayou Corne community:

          And the state's governor has announced plans to visit the sinkhole.

              March 17, 2013 //
              <!-- -->

              The Office of Conservation is advising the public that a large ?burp? event was recorded at the sinkhole shortly after 3 a.m on the morning of Sunday, March 17, related to the recent period of elevated deep seismic activity around the failed Oxy 3 cavern and the sinkhole. As has happened in past events, such as the period of elevated seismic activity that preceded the Jan. 19 ?burp? event, the recent period of elevated activity was observed for several days prior to a sinkhole event. Though the deep subsurface activity appears to have calmed significantly, Conservation?s contracted experts continue to note shallower seismic activity likely related to slumping of the sinkhole sides and water movement in the sinkhole and immediately below it. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions.

                Louisiana officials are grappling with a giant sinkhole that's threatening a neighborhood. A salt mine collapsed last year, creating a series of problems regulators say they've never seen before, including tremors and oil and gas leaks and a sinkhole that now covers 9 acres.

                Residents have been evacuated for more than seven months now and are losing patience.

                Ernie Boudreaux lives in a trailer on Jambalaya Street in Bayou Corne, La. Strange things have been happening to his home, he says.

                "It cracks. You can hear it. The doors pop open by themselves," Boudreaux says.

                The front porch is separating from the trailer and sometimes he smells oil ? all problems that started after the sinkhole opened less than a half mile from his house. His neighborhood is under a mandatory evacuation, but Boudreaux comes back a few days a week to care for his dog, Diesel...

                  There's an update on the activity at the sinkhole over the last few days:


                  March 23, 2013:
                  The Office of Conservation is advising the public that the Oxy 3/sinkhole monitoring alert status has been lowered back to Code 1 ? allowing work inside and around the sinkhole to resume. The rate of subsurface activity being detected by seismic monitoring is reduced in the area around the sinkhole and Oxy 3 area, and the waters of the sinkhole have not shown further signs of movement at surface. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions. The public is also being advised that the 3D seismic work is planned for Sunday, March 24, involving the use of boat-mounted pneumatic equipment on the waters of the sinkhole to generate the seismic signals used to help assess the status of the disturbed rock zone near and below the sinkhole.

                  March 25, 2013
                  The Office of Conservation is advising the public that the Texas Brine is beginning work on the well pad shared by the Oxy 3A and Oxy 9 wellheads in preparation for moving in a snubbing unit to re-enter the Oxy 3A wellbore and clear out blockage currently preventing direct access to the original Oxy 3 cavern. The snubbing unit is designed to provide maximum pressure control in the wellbore to ensure safety of the public and of workers on site. Contractors will be placing wooden mats on the site, as well as moving some of the equipment already stationed on site to make room for the snubbing unit, expected to be moved on site within the next week.

                  March 26, 2013
                  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. Experts with Conservation and CB&I believe the slough-in event is linked to the period of elevated subsurface fluid and gas movement detected late last week in the area around the sinkhole and Oxy 3, as has been observed in previous similar events. At this time, the Oxy3/sinkhole monitoring alert status remains at Code 1, allowing work around the sinkhole to continue, as the slough-in appears to be related to the earlier subsurface activity ? however, monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions.

                  March 28, 2013
                  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

                  There are also 2 new flyovers:

                      Gas found under slabs of 2 homes near sinkhole
                      Posted: Apr 03, 2013 4:18 AM PDT Updated: Apr 03, 2013 12:19 PM PDT
                      Posted by WAFB Staff
                      BAYOU CORNE, LA (WAFB) -

                      Contractors reported finding the presence of gas under two homes near the massive sinkhole in southeast Louisiana...
                      The homes were on Sauce Piquante Lane. I think this is the location shown on this map. (Pre-sinkhole satellite view.) That would be
                      north of La-70, an area suffering most from tremors and odors from reports I've read.

                      A wonderful organization, On Wings of Care, that uses aviation for humanitarian purposes, has been
                      flying over the area and their latest set of of videos has the best documentation of the proximity of the community
                      and highway to the sinkhole that I have seen.

                      Here are a couple of screen captures:

                      An overview from south of La-70 including the sinkhole in the upper right
                      and the bayou winding along the bottom:


                      Now a tighter shot from north of La-70 looking at the sinkhole on the left side of the frame and in the lower right is the
                      part of the community north of the highway where gas was found:


                      More videos, photos and commentary are here:
                      http://onwingsofcare.org/index.php/p...-flyover5.html

                      Since there are residents who have evacuated but occasionally return home to check on pets and do work on their property, this could be a very dangerous situation. A technician with our local gas company told me that a small leak I had in a gas appliance in the garage would likely not cause a problem if I was frequently opening and closing the door to ventilate the area. But if I were to take a short trip and come back - the gas could have accumulated to explosive levels by then.

                          Thanks for the update on that, Tonka. Those movements are certainly unusual. They seem like a condensed version of the seiche waves at Yellowstone Lake.

                              That's slightly unsettling how those trees just sink straight down.

                              Yesterday's news declared it's ok to go back into the water:

                              12:05 p.m. Advisory from the Office of Conservation
                              April 19, 2013 //

                              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 lowered to Code 1 ? allowing work in the sinkhole area within the containment berm. Per Dr. Stephen Horton with USGS, seismic monitoring has detected an decreasing trend of subsurface activity in the area around the sinkhole and Oxy 3 area below the sinkhole over the past few days. Seismic analysts are also advising members of the public following the seismic monitoring data online that the ?LA 10? monitor has been picking up echoes of yesterday?s Pacific Ocean 7.2-magnitude earthquake that occurred off the coast of Japan, but these signals do not indicate any impact to subsurface stability in the Bayou Corne area. Monitoring is constantly ongoing in the area and Conservation will advise the public of significant changes in subsurface conditions.

                              However, looking at the helicorders now, they have been very active since about 7am.

                              Here is the explanation of the code levels:

                              Code 1: Minimal to no seismic activity around/below sinkhole; 10 or fewer of the sharp seismic signals associated with rock movement, called mini-earthquakes (MEQs) or the longer signals associated with gas or liquid movement, called Very Long Periods (VLPs) within 24-hour period; allows work on sinkhole and inside berm area to continue

                              Code 2: Restricts work directly on the sinkhole, indicates some increased seismic activity around/below sinkhole but not at a level that indicates imminent threat of sloughing or movement below sinkhole (10 to 50 MEQs or VLPs in 24 hours)

                              Code 3: Restricts all work inside the containment berm, indicates seismic activity has elevated to a point similar to what has been seen in past monitoring prior to a sloughing on the shore or movement beneath sinkhole (More than 50 MEQs or VLPs in 24 hours)

                              There was a “burp” within the sinkhole this morning as well as a slough in on the east side (of which measurements are not yet available). Water in the sinkhole continues to move which is an indica…

                                Texas Brine Co. is building a westward extension of a 1.5-mile containment berm encircling the Assumption Parish sinkhole because a 200-foot stretch of the earthen wall is sinking, authorities said Friday.

                                The berm has been under construction for months to keep oil, salt and other contaminants from escaping the 13-acre sinkhole and harming surrounding freshwater swamps, bayous and aquatic life...
