Tremors felt 45 miles away from Bayou Corne Sinkhole!

A bit of new film.

enenews.com...

I figured this much would happen to fresh earthwork and ground subsidence.... Any spike in readings so far?

Now back to fixing my leaking roof!

This video isn't as good as the one AirCool posted but this is another video of the flooding.

Reports are saying that the water rose 2 1/2 feet inside the berm. I think this berm was jinxed from the beginning.

CB- get that roof fixed quick, rain is in the forecast till Sunday.

WEATHER: .. FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH LATE SATURDAY NIGHT... I think they can kiss that trackhoe goodbye. Much more flooding and that thing maybe part of the sinkhole.

So, once again man in his arrogance tries to put a leash on nature and nature breaks the leash and bites man in the butt.

When you think about it this was predictable. If it wasn't rain that breached the berm it would have been something else.

It isn't over till the fat lady sings, and she isn't even in her dressing room yet to put on her grease paint.

I have a temp fix on my roof. But on more important notes, Texas Brine has been holding back on residential buyouts. Residents are reporting TB is making no effort at all to attempt buyouts ordered by Gov. Jindal

Which just shows how much of a butthole the whole bunch of them are. How much do you want to bet that Jindal won't step up and reissue the order for the buyout and let TB slide on it. Time is on TBs side, the longer they can put off the buyouts the more chance that many of the affected residents will just give up and move on.

Now is the time for Erin Brockovich to get back into the game. If TB and the government have decided to stonewall the residents, she is their only hope for a settlement that even approaches fair. And, I don't think they will get that "fair" settlement until they carry the case to a federal court because Jindal, and possibly TB as well, most likely "own" the state courts.

Link to IRIS LA12

at 16:30 mark, the spike almost went off the scale. Isn't that a bad sign? But what do they mean is happening down below?

I think I will link to the IRIS plots from my thumbnails as the CERI ones dont show the magnitude(?)

Good Morning and Happy Mother's Day to all!

I was doing some browsing at the Louisiana DNR website and found this interesting update from CB&I dated May 1.

First, a new graphic showing general locations of seismic activity.
Yes, some of the microquake activity is well east of the sinkhole, in/around/above/under? Oxy#2, and getting darn close to Crosstex #2 (isn't that the one that held Butane? Is it now empty?).



This next image shows preliminary locations of individual EQ's, but it is still hard to read--it's easier to open the .pdf above and zoom in quite a bit.
The red dots are Pre-sinkhole quakes.
The orange dots are pre- 19 January 2013.
The purple dots are post- 19 January 2013.
The blue X's say "Oxy 1 microseismic" on the legend (I guess that means very small earthquakes picked up by the Oxy 1 Array?--It's not clear to me (and that is probably very purposeful by CB&I)).

(click for larger)

Here are a few other tidbits from the update linked above.
From page 7 of the report:

Cavern update
– Cavern bottom tag at 3919 feet TVD, 119 feet of cavern remaining as of April 6
– Multiple seismic events in April
– Cavern pressures have stabilized at around 500 psi and so far brine removal has been unable to reduce them

From page 11:

Current sinkhole area—15.1 acres (defined by -10 foot depth contour)
 Total settlement area—37.5 acres
 Area increased 2.7 acres in past month and volume increased 300,000 yd3
 Western 60 feet of Oxy 3 pad collapsed in late March and early April

There is more info in the report concerning the methane and nat gas.

ETA: The fact that microquakes have been located farther toward the center of the salt dome really doesn't give us any useful information, because we don't know at what depths they are occurring. It could be in the cap rock above the salt, in the salt, or well below it.
I guess we can be fairly certain they aren't happening 50 miles down, and that's about it.

Yes sir, #2 does or did hold the butane. #1 holds the NORM.

As for the micro quakes happening around the cavern, could it possibly be the salt inside the cavern falling apart? Kinda eating the dome inside out?

What data would we need to plot the depths and positions? It is outrageous that they are not making this data available but then I suppose they dont want people to know the full extent of the disaster. Depth info would allow us to find out for sure where the dome is falling apart.

The data from 2 or 3 other different stations would allow us to plot the positions but how do you get the depth? Is it part of a normal helicorder dataset that is collected or does it have to be calculated from the other data? ISIS obviously have the data since the graphs are created in realtime from that. (or else they are downloading the graph from somewhere else to show on their page)

Loud explosion heard in Bayou Corne at 7:30 cst. Will follow up when I get more info.

They believe the explosion was a transformer. Entergy our state power company (don't get me started on them) did not confirm it yet.

I realise this a very old article but we were talking about the other caverns and so it is relevant.

This article from 12 Aug 2012 suggests that the butane will not be moved, so we have to hope that the collapsing of the sides of oxy3 does not spread to other areas or the microquakes do not cause the other caverns to start to collapse also.

The Examiner See also the plot on the right hand side which has a title of ..."activity on 9th Oct 12 before the slough-in". Looks very similar to what is happening on the plots at the moment.

Morning All! Just wanted to link this article. Freedomrox has done some great writing about the sinkhole. I am going to have to read this all again because I find I keep having more question and concerns. I keep thinking why would they do this, then what????

Sonny Cranch did not Answer… as to why gas would be in Oxy Geismar #1, although it has to be vented, sometimes twice a day since before the sinkhole first appeared, and a Blow Out Preventer, (BOP), installed before the removal of the seismic array. Nor will anyone state what gas was involved. It doesn’t take a lot of imagination here to understand which gas though. Question most likely is; where exactly is the fracture in Oxy #1?

You all certainly do not need a spark in Bayou Corne. Some gasses are heavier then air and some aren't. I would say keep your butts in your cars and Entergy should keep their equipment tip top.

Did they ever confirm that it was a transformer? Pockets of gas can cause some loud explosions without damaging much of anything else.They just need an ignition source and those aren't to hard to find. I've theorized on other threads about the loud booms all over the country that some of them may be caused by plumes of gas in the air. Methane is lighter than air and will continue to rise once it's released from the ground and hydrogen sulfide on the other hand is heavier-than-air and will rise up when released but slowly drift back down to the surface in plumes. Your area would be a perfect candidate for this with all the methane and hydrogen sulfide bubbling up.

I found this new video...

There is an awful lot of water flowing INTO the sinkhole. Where is it going to and how much more damage could it be causing by erosion?????

Good find HappyKat. The rate that the water was moving there is now way the oil could have been contained. The oil that usually sits on the sinkhole is somewhere down stream. What a mess.

I notice that they mentioned the buyouts at the end off the news cast. Plus HK mentioned it last week. Those buyouts looked like they were going to happen right after Brochovich and Jindal visited, they said it was going to happen then when cameras turned off, that nonsense (sarc) talk of holding Texas Brine accountable stopped.

To go with olivine's pdf of the Bayou Corne sinkhole May update meeting, you may want to look at
this pdf from Feb 2013 which I recently acquired.
It seems this was used as a basis for the public briefing pdf dated 1st May and gives more
detailed information - although much of it is at least 2 months old !!.

Drip-feed of information eh? One drop at a time.

It gives a reason why the gas must be vented - because they cannot get the residents back in their homes while it is still being detected. By venting it in all these places, they hope to reduce the pressure so that it does not seep up through the ground, but on the other hand, they dont know how much gas there is down there waiting to come up... Could be a whole gas field so it might be like pissing into the wind... useless.

If the water is flowing into the sinkhole, then it may be finding its way through the rocks the same way the gas is. If it IS, then it may be dissolving the salt in the salt dome and possibly that is what some of the small micro-earthquakes are about. They would be the salt dome collapsing from the unplanned and unregulated dissolving of the salt at the side, or even at the bottom.

We already know that the Oxy3 cavern is "nearly full" from the sides caving in and the pdf linked above gives more details on that too. However, if the sides cave in, then that will cause more instability around where the cavern was. The material at the sides which "caved in" is other salt from the salt dome and must leave a hole where it came from which causes more unplanned and unmonitored edges to the larger salt cavern which once was Oxy3.

Basically, it appears to me as if Oxy3 is going to grow and will no longer look like the nice picture we are being shown.

10pm CDT - More serious problems at LA11, LA14 on the helicorder Those who understand these things please look. What is the large block at the top of LA14 etc?

helicorder 12-hour chart LA11
IRIS 24 hour chart


helicorder 12 hour chart LA14
IRIS for LA14 seems to be offline or broken link or something.

LA12 echoes the same thing but a little less

LA10 which is in Oxy3 shows it as well. but the IRIS graph for that one (without the clipped spikes) is not showing up either for the last couple of days.
