An Assumption Parish sinkhole’s edge collapsed following increased underground seismic activity for a third time in 16 days [...]

SOURCE: WAFB

Experts have known for months that tremors precede edge collapses and other side effects, but the pattern this month appears to be cycling at a faster rate than previously.

Patrick Courreges, spokesman for the Louisiana Department of Natural Resources, said experts think the quickened pace indicates the cavern suspected of causing the sinkhole is getting close to getting full of surrounding earth, causing subsurface shifting movements to occur at shallower depths. [...]

[John Boudreaux, director of the Assumption Parish Office of Homeland Security and Emergency Preparedness] said it will probably be next week before work can be resumed following the latest tremors because small parts of the well pad were still breaking off and falling into the sinkhole as of Thursday afternoon. [...]

    The water from the aquifer is making its way into the cavern.
    Oil is coming up the sinkhole.
    The situation is accelerating…
    "It's catching its stride".
    Sorry… no better explanation…just the mumbling of 'wild catter' talk..as she brushes her hat..across her knees..a couple of times.

    Damn it..

    I don't buy the story that Oxy#3 is almost full of rock and sand. The sinkhole hasn't grown enough for that yet. It may be full of fluid at the top, but not of solids. True that there might be large bubbles rising to the surface, but that wouldn't make up the difference between the size of the sinkhole and the cavern in its original state. I expect the sinkhole to double in size from its current state before it stops growing.

      dosdos…..what's in the cavern now has no relation to the sinkhole. Haven't you been listening about the massive voids? That's where the cavern fill is coming from.

        The voids don't just appear from nowhere. Gravity sees to that. The voids are the pockets of gas space in the cavern moving upward through the strata as the cavern is filled with rock and sand by gravity. In short, it is displacement of the cavern space. There is not enough strata between the cap and the surface to hold all the voids that the cavern would created if it were already full of fill rock and sand. Hence, the a fair percentage of cavern space is still below the cap, the cavern is not filled yet.

        The sinkhole should pan out at about 30 acres. When it's that size, the cavern will be filled and the voids cleared the surface. That's when they can call it contained.

          Sorry dosdos,but that is incorrect. I know the voids don't just appear from nowhere.The voids are left behind when the rubble enters the cavern.The voids ar NOT in the cavern. The cavern has been filling up. The sinkhole has not gotten any deeper. The debris in the cavern can only be account for by assuming there are massive gas pockets/voids.

          Last I heard, the cavern was at 89% full and that was several weeks ago. Not sure why you would choose to believe they are saying the cavern is filling up (floor rising) if that wasn't the case, as it only makes for a worse scenario for them, with the voids being left.

    I live here (60 miles out), and to be honest, it needs just to go ahead and reveal itself. Frankly, Im sick of the willful ignorance around here. Maybe if it gets worse things might actually start to get better in the long run.

  • how deep is the cavern? Couldn't the material from the roof of the cavern falling inside, explain the elevation of the seismic activity? I imagine if I were sitting inside the cavern and the roof kept continually falling in …

    The sub-parellel area between the sinkhole and the SIDE of the salt dome is collapsing..so goes the top of the dome eventually.
