I think it just burped.
Check the waveform at 17:19 LA CST- on wards.


I cross checked the time frame, but the only quake showing over a M4 is around 17:05 00:05 UTC.

The sinkhole area is now in Red Alert. I'll be getting a word why soon. Go back to the article Happy posted to get an idea of the color scale they implemented last week. Work has indeed been halted. Hold on to your seats, we may be seeing sinkhole #2 and a new world of environmental hurt.

Here is a QUICK LINK to the posting CB is referring to.

And a DIRECT LINK to the article. The contingency plan with the explanation of the alert color levels is near the bottom of the page.

And, finally, the text of the red level section of the contingency plan.

Red

Seismic Activity: Several hundred micro-seismic events associated with Oxy 1 Cavern stability detected during any 12-hour time period. Action steps include:

1. Immediately notify Assumption Parish Officials, GOHSEP, and State Police that activity has been detected demonstrating that Oxy 1 Cavern shows signs of ongoing structural instability and that surface impact associated with Oxy 1 Cavern may be imminent. Evacuation will be recommended to local officials.

2. Shut in all natural gas vent wells in the Bayou Corne area due to the potential for H2S release from cap rock in the event of a roof collapse of the Oxy 1 Cavern. Natural gas vent wells will remain shut-in until appropriate H2S safety measures are implemented.

3. Notify all operators in the area that structural instability of the Oxy 1 Cavern is ongoing and to take all appropriate actions to protect safety and the environment.

The next cavern to collapse is a brine cavern. The butane cavern is in a questionable state.

That is a relief for now. But I think we will be facing the third, and more dangerous, sinkhole pretty soon if the second one opens up. Then it will really be TSHTF time.

But there is still a potential for release of a lot of natural methane and/or hydrogen sulfide. While that is nowhere near as bad as it would be if the cavern contained the butane, it could still prove to be deadly for people in close proximity to the cavern. Hopefully they are going to evacuate all the people in the danger zone before that happens.

It is a sane move but like Kat said it is a lose lose almost. That gas has to go somewhere & they drilled to relieve the build up. I just worry about building of pressure by shutting the vent well, then liquid or gasses are shifting all in an unstable area. As far as I recall that collapsed cavern has not filled and stabilized yet. I guess we can be grateful that the rain has finally stopped because that seemed to exacerbate things.

Another bump at 22:34 CST looks significant.




I'm not sure I'd be sleeping easy if I lived near there.

I really wish I have a live feed for GEE so I could see the wave forms better.

This has been posted several time before, but it is an important link to the helicorders for the sinkhole area and needs to be posted again.

They are updated in near real time which makes them useful for watching developments.

CERI Helicorder Page

Here is a map showing some of the helicorder locations. It is out of date a little. If someone has a link or picture for one that is more up to date I would appreciate it.

Here you go:



It can also be found in this post from page 58.

Me, too.
The original seismos around the sinkhole were available in GEE on the GS network. But they have renamed them and switched to the YC network, which I can't seem to get to load in GEE.

Thank you Olivine. That is what I was looking for. It shows the locations of the important helicorders. It would be nice to have an even more up to date map but this one will serve our purposes nicely.
