wow, well I'd been having trouble accessing that network in my bigger program, (not GEE) but I FINALLY was able to get it to work! Halla-ficken-lullia!
Now I got spectro on the entire mess- all LA stations. And this lets me see the actual seismicity easily through the other man made noise. And there is A LOT of noise. A lot of what you see on the helicorders is not seismicity. But lately, a lot of it is. What is baffling is the long period events- they are more typical of...of... volcanoes...
And yeah, I saw the post about the ancient volcano under LA. I am not suggesting...well...I think...umm...

I'm hoping someone can help me out. I thought I saw it posted somewhere here, either on a vidieo or text the "ppm" the methane was at one point. I thought it had something to do with that "Minden" explosion, but after doing a search I can't find it. I'm sure it's there, I just can't find it.
The reason I am asking is, I am trying to figure out how much higher the levels are now as apposed to then.
I have been going back on all the information, I'm getting confused. TMI. But for some reason I think this might be important.
In a startling new development methane is now beginning to bubble up through the ground. As this disaster escalates some residents can expect to be 'blown up' in their own homes, just by turning a light on! See comments below, this bubbling is related to the BP deep well disaster.
The high pressure (800 PSI) and high temperature (400 F) crude from the BP deep well blowout has been seeping into and melting an enormous deposit of methane hydrate beneath the Gulf of Mexico. The methane hydrate expands by a factor of 160 to 1 and the liberated gas is migrating throughout the Gulf states. As the gas enters into existing underground cavities under high pressure it causes the movement of rocks and earth. Sparks from the rocks moving against each other, are no doubt igniting the volatile methane and causing the earth tremors and booms that people have been reporting in several Gulf States. This disaster is going to take many lives, if you know anyone in the region please forward this link to them.
"Cracks and fissures are opening up on the sea floor over an area of several miles. A number of 'pock marks' have appeared on the sea floor as far as 20 miles away from the original Macondo blow out.
"Oil and methane gas are escaping from areas that have never even been drilled," Jackson wrote.
Frighteningly, these fissures appear to be growing and connecting with each other. The methane pockmarks are growing in size. Even worse, the weakened sea floor is being heaved up into a massive, fracturing, mound. A geological time bomb, previously locked away under miles of rock, has been disturbed. Fear is growing for the very grim possibility that a methane gas bubble, 15 to 20 miles in diameter, could indeed rupture the sea floor and escape with unimaginable violence.
"This is the most vigorous methane eruption in modern history," said John Kessler of Texas A & M University. The oil contains 40% methane - much higher than the usual 5%.
Kessler found that underwater methane in some areas approached "a million times above background concentrations."
In addition to methane, the EPA has found extremely high levels of benzene and hydrogen sulfide in the Macondo Prospect investigations, the same chemicals that officials have detected in the Bayou Corne area and that locals there can smell.
In 2010 Macondo investigations, early H2S readings were 1,200 ppb - far higher than the allowed 5 - 10 ppb.

The sinkhole site was evacuated because of high seismic activity. It was done in fear that the second hole may open up while the workers are working.
Lets just sum it up by saying that I sincerely hope that I am dead wrong about both of them. But the evidence is continuing to point in the direction of a disaster beyond anything we have seen since man first started to walk upright.

As an alternative, could a collapsing salt dome cause long period events at those frequencies? Well I dunno. Never had the occasion to monitor a collapsing salt dome before. I wonder if they have either.
VLP—Very long period seismic event (indicates fluid flow)
(bolding by me)
– High resolution seismic imaging of Disturbed Rock Zone looking for overall
size, internal structures, void spaces. Uncertain if this has ever been
attempted on a collapse structure.
– Identify the possible gas source zones and potential for intercepting gas
– Potentially can identify shallow gas areas but this is uncertain because gas is
shallow (~100‐120’), thin (2 to 10’thick), high water saturation (>50%)
– Don Marlin, CPG, will do independent analysis of 3D seismic data
