Recent observations on Yellowstone for serious magmatards
Greetings fellow magmatards.

This is a bit lengthy, and intended for serious magmatards so please read through this and follow the links carefully. Please read the whole post to understand the point that I am trying to make.

Thoughtful commentary and opinions are always welcomed, as I am only an amateur and not a professional geologist.hf

I just wanted to make you all aware of some interesting observations about the Yellowstone caldera that I have made over the past several weeks. I have a personal interest in this, as I live in Wyoming, so any problems at Yellowstone would be likely to affect my family and me.

The first interesting thing is that over the past two weeks, two new sensors were added to the seismographic line up. These are the YPC- Pelican Cone and the YMS- Mt. Sheridan sensors.

The YPC sensor was apparently inactive or abandoned for 8 years, and now suddenly it is “on” again with no real explanation.

[link to isthisthingon.org]

The YMS-Mt. Sheridan sensor is now similarly active, with no apparent explanation, but it is the YPC- Pelican Cone sensor that I find the most fascinating.

Both of these sensors appeared suddenly on October 7th after having been inactive for years.

[link to www.isthisthingon.org]


[link to www.isthisthingon.org]
[link to www.isthisthingon.org]

The YPC sensor was initially at 100 mv (a low setting, so it looked really inky for the first 3 days. (The YMS was also set at 100 mv as is the YMR) Then without warning again, the volume was adjusted to 500 mv on October 10th.

[link to www.isthisthingon.org]

The YPC was abruptly shut off again on October 11:
[link to www.isthisthingon.org]
This was the same day that the YMS sensor was adjusted to 800 mv
[link to www.isthisthingon.org]

Those of us who have been following Yellowstone for awhile know that the USGS tends to turn the sensors down a bit if they look too “inky”. (YNR-Norris has been a prime example of this in the past) worship

YPC was then restored on October 12, but at 1600 mv, where it resides currently.

[link to www.isthisthingon.org]

The next interesting part is that at the1600mv setting, a pattern develops usually once or twice daily of bursts of high frequency waves, followed by a short period of smooth undulations with a return to the sharper saw tooth pattern. This doesn’t really look like road construction or any other man-made activity that I am aware of.

Here are these patterns from October 12 to October 21 in chronological order when something even more interesting occurred.

Now here is where it gets really interesting. On October 21, when the 7.4 Pacific earthquake occurred, almost every sensor in Yellowstone as well as most throughout the world picked up this earthquake well. On most of the other Yellowstone sensors the P and S waves from the 7.4 earthquake showed up very well, except the YPC sensor and a few others (YMP, YMS, YPP, YML and YMC also did not show the earthquake well)

(Information on P and S waves)
[link to www.thetech.org]

[link to www.geo.mtu.edu]



Here is a comparison of the YPC sensor of the earthquake starting at 11:10 local MST time recording at 1600 mv followed by the YPK sensor also recording at 1600 mv. The YPK sensor shows the earthquake tracing,

The YPC shows next to nothing and then its usual pattern over the previous 10 days. In short the YPC did not really record the October 21st earthquake in the same fashion as most of the other Yellowstone sensors did, with just a baby P wave and no real S waves that I could see.

YPC on October 21 @ 1600mv:

[link to www.isthisthingon.org]



For comparisone the YPK on October 21 @ 1600 mv:

[link to www.isthisthingon.org]




This perplexed me, and on the El Hierro thread, a similar phenomena was noted, as the actively erupting El Hierro sensor did not really pick up the October 21 earthquake, while the surrounding sensors as well as those almost world wide did show it very well.

There was discussion on some of the geology threads about how the magma chamber on the actively erupting El Hierro possibly blunted the S wave propagation.


· “Now I pointed out to @teideano that 7.4 tremor in the pacific last evening was recorded in all the Canary Islands seismic stations but El Hierro.”
· “S-wave blocking by the magma chamber would be localized below El Hierro and not affect seismometers on other islands.”

[link to storify.com]

This made me curious if the same phenomenon might apply to Yellowstone, causing the more superficial and liquid magma plumes to respond to the earthquake with no or very blunted S waves (& also P waves).

I found this from a discussion of the Long Valley super volcano in California:

“Another type of seismic wave effect that can point to a body of magma is called attenuation. As mentioned earlier, fluids generally do not support much S-wave propagation, as they do not have shear strength. A body of magma could therefore be expected to block, or at least attenuate, S-wave propagation through it.

[link to www.indiana.edu]

More of this S and P wave attenuation phenomenon with shallow magma chambers:

[link to www.springerlink.com]
[link to www.earth.sinica.edu.tw]
[link to redalyc.uaemex.mx]


The YPC sensor is near Pelican cone, just outside the old caldera boundry:

[link to img.docstoccdn.com]

Anyway, what I have been wondering is there a shallower and more molten “finger” of the Yellowstone magma chamber located near the YPP sensor, and was this sensor recently reactivated to follow this area more closely. Yellowstone has had non-super volcano eruptions as well as super volcano eruptions. The most recent non-super volcano eruption was about 70,000 years ago with the largest area near YPP- Pitchstone Plateau.

[link to volcanoes.usgs.gov]


Could something new be brewing near Pelican cone? This area is near one of the two resurgent domes called Sour Creek, (with the other being Mallard Lake) just east of Yellowstone Lake.
Is the magma flowing under Sour Creek dome starting to find a new upward passage near YPP instead of circulating back toward Mammoth?

“Wicks and his colleagues believe that magma is rising from beneath the Sour Creek Dome, in the caldera’s eastern section, where it hits the solid mantle layer and spreads out like a thick pancake.
Something different is going on,” said Wicks. “There’s a continuous flow of magma under Sour Creek Dome. As the magma loses heat and cools, it dives back under Mammoth,” he said.”

[link to www.yellowstonepark.com]
[link to www.uusatrg.utah.edu]



I don’t know the answer to these questions, but I find them interesting especially since the YPP sensor has been reactivated after an 8-year dormancy.

Perhaps this is all just coincidence, but GLP I think exists to discuss ideas, and kick around topics that may be censored elsewhere.

I will try to check back and update this thread for new findings and information.

Thanks for the bump s

I really appreciate them, maybe we can get a really interesting discussion that helps us better understand these monster volcanoes and how they behave and when they might cause problems.

I really don't mean to imply that Yellowstone is "waking up", but rather to help explain these recent and troubling (to me anyway) observations. hf

There has been so much activity recently with respect to volcanoes and earthquakes, it is now time for serious and open discussions about these matters. eq

I just checked it's still there and has been ongoing since 2008, it's miles long, "Whats going on at...". The thread had lots of graphics and links, don't know if those are still there because you might have to sign in to see 'em and I don't feel like it. Also some pretty creepy trolls, standard issue there. I cut my Yellowstone toothies on that thread, saw first-hand the machinations. It was following a different thread here on the same subject that pulled me into this place.

The thing that concerns me about the lack of data at other places, as well as Yellowstone, within a limited timespan, is the possibility that it may point at an overarching driving force (let's just make something up and say it's cosmic alignments affecting the sun) that is known to some and kept from the rest (us).

Re: Recent observations on Yellowstone for serious magmatards
Good job here! I'm not a magmatard but I used to read somewhere that yellowstone is overdue for eruption. I really have a feeling it will blow very very soon like a sip of tea. This is based on my feeling though. This world is long overdue for many things, meteor strike and volcano . All 16 volcanoes in Indonesia alone on red alert, aira VEI 7( the one inside its cone had massive eruption yesterday). They all seem to wait for the big guy or maybe they are the opening sequences for the big guy.

Re: Recent observations on Yellowstone for serious magmatards
First, let me congratulate you on a very astute observation and interesting thread.

If you go to the Yellowstone map of stations here:
[link to www.quake.utah.edu]

And take a look at where YPC and YMP are located, I thought you might be interested to see YMP's webicorder for 10/21 on that quake:
[link to www.quake.utah.edu]

It isn't even there! And with a sensitivity setting of 1066 mv, vs YPC's of 1600 mv, the signal should have been even stronger than YPC's, but it's not even there.

And you see that YMP is only like 10 km north of YPC! So clearly, there is something attenuating both P and S waves (like a shallow magma chamber)- OR YMP is not functioning properly. And in Yellowstone that happens A LOT.

ICE. A main culprit of telemetry error at Yellowstone, and something they battle constantly. Many of those spikey, thin vertical lines on seismos at YS are due to ICE.

Notice also that YSB, even further north than either of those (and further from the 7.4 epicenter) recorded it clear at a 1333 mv setting:
[link to www.quake.utah.edu]

With that being the case, I am inclined to first go for a malfunctioning station. Generally speaking, after watching YS for years and yes, participating as a regular on your trippy site there, we usually don't see a situation where attenuation is so great on teleseisims (quakes from far away) at any one particular station.

Then again, I can't say I have really been looking out for that- essentially doing your own amateur seismic tomography of sorts from observation of differences in registered teleseisims at various stations.

Very curious indeed, but am inclined towards station/digitizer or other network malfunction. Just my $.02.

Re: Recent observations on Yellowstone for serious magmatards
Thanks to all of you who responded for your pleasant discussion and commentary and stars.cheers

Mr. Quake, thanks for posting the station map. hf I should have included it in the original post, but became overwhelmed with the links that I was trying to include, so thanks for adding that.

If you will look at today’s maps (10-23-11) either through the University of Utah site or the “isthhisthething.org” site you will see the recordings for today’s 7.2 eastern Turkey quake showing very similar attenuation patterns to the October 21 quake attenuation patterns.

(I tend to like the “isthisthething.org” site because you can see all of the active sensors at once.)

[link to www.isthisthingon.org]


I usually discount the LKWY site a bit, because that sensor looks like it often has some type of glitch in it., but even that one recorded the S waves from today’s quake.

[link to www.isthisthingon.org]

Likewise the YMC sensor doesn’t seem to record much of anything ever, so I have often thought that it was just broken, and it did not record today’s quake either. (I am hoping that it is not because there is a reaalllly shallow magma chamber therehiding, but I was thinking that the YMC sensor is broken because it never seems to respond to anything in a very seismically active area like Yellowstone.)

[link to www.isthisthingon.org]

The YMP is interesting, because it also barely responds to anything as well, so I thought maybe it doesn’t work very well, but maybe something is going on there as well. It is very close to the YPC near the sour dome area.

[link to www.isthisthingon.org]


The reason the YPC caught my eye is because it reacts to a lot of other stuff, and seems fairly active, reacting well to other stimuli. Because it reacts well to the other stimuli, I don’t think it is frozen or that ice would cause it not to react to the S waves of large quakes, as it still seems to respond to its local environments, marching to the beat of its own drummer, so to speak. There were no significant S waves from today’s 7.2 quake. but there were other responses, so I tend not to think it is frozen.

[link to www.isthisthingon.org]

For comparison and contrast the nearby YPP also at 1600 mv shows today’s quake well:

[link to www.isthisthingon.org]


Here is the tracing from the full day of the YPP on October 21. As you can see, there were no significant S waves from the Pacific quake that day which did hit the other sensors at around 11:10 (local MST), with S waves generated from around 11:41 (MST) through 12:00 (MST) with the peak being at around 11:45 (MST). In simple terms the largest waves was on the first part of the 11:45 (MST) green line for the other sensors, but not the YPP. It showed a completely different pattern, much more similar to its patterns the previous week. The 11:45 (MST) green line was relativity quiet while the subsequent lines were more active. It was also quite active later that day, and therefore I do not believe that it was frozen, but rather it is attenuating S waves of distant quakes, while very much marching to its own much more local drummer.

[link to www.isthisthingon.org]

In comparison here again is the nearby YPK sensor demonstrating how most of the other park sensors responded on the 10-21-11 Pacific quake, which was quite a different response from the YPC, even though both are set at 1600 mv.

[link to www.isthisthingon.org]



So, I still think there is evidence for some type of anomalous behavior of the YPC sensor and possibly the YMP sensor. This may be related to a shallower magma chamber than else where in the park or other factors of which I am unaware. I realize that the type of understructure influences the S wave propagation, and there are probably other substructures that dampen S wave propagations, but in Yellowstone, the thought of shallow molten magma must become a consideration.


I am not trying to be a fear monger here, just trying to bounce some ideas around about some recent observations. I will certainly be watching this further today to see how the YPC responds the rest of today, and in coming days and weeks. YPC sensor suddenly goes offline I will know that the guys in Utah are messing with us. dcomp

Thanks again for all of your responsessmile_kiss

Another thing that may be affecting this is the type of channels and frequency filtering they are using at different stations around YS.

Some may be set for particular purposes, and it could affect what frequencies it is "tuned" to.

But if you like I can shoot JL an email at the YVO and ask, or you could. I am sure there is probably an explanation.

Re: Recent observations on Yellowstone for serious magmatards
Here are the seismographs in the Canaries showing the same phenomena form today's (October 23) earthquake in Turkey.

Actively erupting El Hierro showed almost really no impact from the October 23 7.2 earthquake in Eastern Turkey, as the shallow magma chamber seems to have severely attenuated both the P and S waves. This is interesting, because the sensor is very active, showing the harmonics of the currently erupting EL Hierro but the earthquake is not displayed even though this earthquake rung the sensors worldwide like a bell.

[link to www.01.ign.es]

For comparison here is the seismograph from nearby Fuerteventura:

[link to www.01.ign.es]

Here is the nearby Lanzarote:

[link to www.01.ign.es]

Here is the nearby La Gomera:

[link to www.01.ign.es]

Here is the nearby Grand Canaria:

[link to www.01.ign.es]

Here is the nearby Tenerife which appears to be on a different scale (sorry, I don't read Spanish well) but still shows evidence of the quake:

[link to www.01.ign.es]

And as for La Palma, that one seems to have been shut off hidingfor a while with no explanation that I am aware of :

[link to www.01.ign.es]


This was also noteworthy during the October 21 earthquake in the Pacific with the same result. This was what started me questioning the same apparent phenomena and wondering about the shallower magma areas of the Yellowstone volcano, which seems to behave similarly in not displaying large earthquakes that are picked up well by surrounding seismographs as well as global seismographs on especially the YPC sensor.

Food for thought anyway.

Have a happy Sunday evening everyone.hf

EmeraldEye, thanks for the thread, I have it pinned.

In terms of volcanism, there is a lot of activity now. Three or four going on Kamchatka, for example. A quake or two in WA state.

Do you visit Eruptions @ wired science? Lots of good data there. I am sure you would have many good discussions with others of similar mindset :)

Re: Recent observations on Yellowstone for serious magmatards
EmeraldEye, thanks for the thread, I have it pinned.

In terms of volcanism, there is a lot of activity now. Three or four going on Kamchatka, for example. A quake or two in WA state.

Do you visit Eruptions @ wired science? Lots of good data there. I am sure you would have many good discussions with others of similar mindset :)

Thanks friend.hf

Yes, I have been there as well as several other sites.

They are talking about El Hierro, but quiet on Yellowstone for now.

Jon Firmann has a very good blog about the Iceland volcanoes, but he also covers other events such as El Hierro:

Nothing move as fast as GLP though in terms of exposure and breaking news when events happen.

The Yellowstone seismographs in general picked up the earthquake in Turkey, just as they did around the world.

What is unusual, and the topic of discussion in this thread, is the differential way that those various seismographs throughout the park reacted and why they did so.

lol, I just realized that "TIA" means "Thanks in Advance" or something, and is not your name... Sorry emerald.

Anyway, I'll see if I can get an email out today or this week- would have been useless over the weekend.

Re: Recent observations on Yellowstone for serious magmatards
It would be interesting to talk to the park rangers around Pelican Cone. I wonder if there have been any changes in the land or the animal population. If the magma is moving close to the surface, the animals could sense it. They know these things way before people do. If the Animal population is moving out, it could be that something is coming soon. It could also be that land is rising on top of the magma. That has happened in Yellowstone before.
Hope for the best, but prepare for the worst.

I posted this on the El Hierro thread yesterday, but it also belongs here. I think serious magmatards will enjoy reading this. BTW "TIA" was meant to be "thanks in advance" but I kind of like the sound of it, and will adopt it as my GLP nickname.hf

"Attenuation in gas-charged magma"

"Magma is highly viscous and above the nucleation depth contains gas in the form of bubbles. Chouet(1996a) suggests that such a gas-charged magma is highly attenuative, very quickly damping any seismic waves propagating within it."

Yes, it would be very interesting to get up there and speak to the rangers.

I wish I had time to go right now, but maybe someone else does, who is closer, and could report in. I would also like to know if there have been any new thermal features in that area and what the temps are and if there have been changes in gas or other compositions.
