Very basic explanations...look at example links..I'd like his answers better though

Thanks. That's one of the sites I couldn't find a link for.

What do you think? Doesn't the wind noise we've been seeing look a lot like the wind noise in their example? The only difference is the amplitude. The sites in the YS area that get wind seem to really get nailed when it blows.

I suspect that a windy night at "geyser peak" may be a calm day for some of Wyoming ;-)

Anyhow, that was one of the links I was thinking of.

The dough definitely seems to be rising!

i wonder what would happen if you threw in a few thousend pounds worth of bakeing yeast into one of the geysers at YS would the ground rise?

I'm not trying to be funny when I say go see a Psychiatrist. You are demonstrating classing Schitzophrenia. No shame in it, but you truly need meds. Don't take my word for it, just go see a trained doctor. Please.

That is a fantastic page with the wave files. As I was playing the first one my two dogs got quite agitated. Since we are in Ireland I doubt they have ever heard an earthquake. Interesting. What an eerie sound!

Neither, I think they're just teleisisms. Geogeek and I were talking about this before, they seem to just show up better in the rocks at this part of the park. I was skeptical at first but then I noticed this trend continued. There were a couple of bigger 5 ish magnitude shakers in papau and china earlier. You'll notice the distance between the first and second waves. In a local quake, they stand straight up like a spike and come in one after another.

Yeah after looking at some of the wind anomolies in examples from a few places that was my conclusion also...and as noted by many here every region has its own quirks in how they setup Equipment and display info

I would agree that those look like earthquake clouds from the pictures I've seen. If truly a predictor, that's concerning. You're in Tennessee?

OK I'll buy that for a $...just plain 'ol good ground coupling in solid granite

reply to post by VX-7R


Wow, that is one weird sound. Is that really from Mt. St. Helen? That is strange. Listening to it, also caused a huge headache for me. It sounds like heavy equipment being banged up and down and then a whistling pipe thing.

Thanks for the link.

It doesn't matter where someone is, if yellowstone blew, we are all screwed. My point is in my videos, there were the waves as shown in pics of earthquake videos and does that mean, yellowstone is emitting gases and vaporization etc? Those type clouds as the sat. shows in an earlier post of my where throughout the whole U.S.

I too have been watching the outflow situation for some time and at the site you posted, if you click on the "Cleaned and Detrended" and then the "Last 30 days" you get a much clearer visual picture of recent movement. LKWY

here is one, is this what U are referring to ?
www.isthisthingon.org...

Yes. That's the kind of thing.

Earlier, just before that station started having real problems, there were a lot of that kind of even-amplitude, abruptly starting/stopping signals.

People were convinced that it was harmonic tremor.

I felt that it looked entirely too uniform and "well mannered" to be anything but man-made. Natural things just don't look like that.

But people were really terrified of it, thinking that it must be harmonic tremor.

And then we got into all kinds of discussion of what it might or might not be.

Someone contacted one of the scientists at the park and that person said that they thought it might be an air sampling system's motor switching on and off again.

Then someone said that it couldn't be that because they'd use something far more high tech, with no moving parts, and especially so since it'd be near a seismic station.

I then pointed out that the current EPA-mandated air quality monitoring methods for particulate *require* that a pump be used, and I posted a link to a manufacturer's site showing the very equipment that is, in all probability, being used. That gear uses a rotary vane pump to draw the air through the filter material.

Anyhow, it was all total speculation, but to me, the most logical explanation was that this is man-made. And the further explanation, offered by one of the actual scientists on scene made sense to me.

But hey, if people want to believe that it's harmonic tremor, I guess I shouldn't rain on that parade.

To me, far more interesting is this:

What's that stuff starting at about 13:37, going for about a half hour, and showing on many of the stations in unison?


Edit to fix my bad link!!!

Here is a reference to a 17 year study of ground movements at Yellowstone by researchers at the University of Utah. Some interesting stuff here. It used GPS to examine data from 1987 to 2004.

www.physorg.com...

The study was published in the Journal of Geological Research - Solid Earth on March 2, 2007 as follows.

Puskas, C. M., R. B. Smith, C. M. Meertens, and W. L. Chang (2007),
Crustal deformation of the Yellowstone–Snake River Plain volcano-tectonic system: Campaign and continuous GPS observations, 1987–2004

Here is a link to the journal.

www.agu.org...


These comments from the first link are interesting given the information posted on this board about uplift.

While not part of the new published study, Smith reported at an American Geophysical Union meeting last December that 2004-2006 GPS measurements show the northwest caldera area sank by 3.2 inches, but the central caldera floor rose faster than ever recorded: about 6.7 inches since mid-2004. "The rate is unprecedented, at least in terms of what scientists have been able to observe in Yellowstone," Smith says.

"We think it’s a combination of magma [molten rock] being intruded under the caldera and hot water released from the magma being pressurized because it’s trapped. I don’t believe this is evidence for an impending volcanic eruption. But it would be prudent to keep monitoring the volcano."

Puskas adds: "This episode may represent a period like those observed at other large volcanic systems such as Long Valley caldera, California, where episodes of unrest have lasted one to four years, with uplift rates as high as 4 inches a year." The fact some GPS receivers now are permanently installed in Yellowstone and provide data daily made researchers realize that ups-and-downs of the caldera occur not just in decades or years, but in months, reflecting underground movements of molten rock and hot water that "also happen over months," Puskas says.

Well the group on this board is sure monitoring the volcanoe!!

A few big jumps in your post.

I agree that the clouds you videoed have some interesting patterns. I am curious as to the theory behind earthquake clouds. Are they supposed to occur in proximity to the coming quake or do they simply indicate that conditions are prime for a quake to occur somewhere? (That's why I wanted to know where you shot them.)

As far as the satellite image you showed me, the clouds seem to have interesting patterns about them, but I'd need to see that photo compared to other times both before earthquakes and in normal conditions to get on board the assertion that the entire county demonstrated the same pattern.

What was so different about that satellite photo from usual? I want specifics... What am I looking for?

YPP's gone wiggy again. FYI it looks completely fine in GEE. Just some weirdness with the webicorder?

Anyway, like I said the live feed in GEE doesn't look like that, so don't freak out!

"...Earthquakes in the central or eastern United States affect much larger areas than earthquakes of similar magnitude in the western United States. For example, the San Francisco, California, earthquake of 1906 (magnitude 7.8) was felt 350 miles away in the middle of Nevada, whereas the New Madrid earthquake of December 1811 (magnitude 8.0) rang church bells in Boston, Massachusetts, 1,000 miles away. Differences in geology east and west of the Rocky Mountains cause this strong contrast.

1895 Charleston, MO earthquake (Click on image for a full size version - 63K)
Although earthquakes in the central and eastern United States are less frequent than in the western United States, they affect much larger areas. This is shown by two areas affected by earthquakes of similar magnitude-the 1895 Charleston, Missouri, earthquake in the New Madrid seismic zone and the 1994 Northridge, California, earthquake. Red indicates minor to major damage to buildings and their contents. Yellow indicates shaking felt, but little or no damage to objects, such as dishes.

The loss of life and destruction in recent earthquakes of only moderate magnitude (for example, 33 lives and $20 billion in the 1994 magnitude-6.7 Northridge, California, earthquake and 5,500 lives and $100 billion in the 1995 magnitude-6.9 Kobe, Japan, earthquake) dramatically emphasize the need for residents of the Mississippi Valley to prepare further for an earthquake of such magnitude. Earthquakes of moderate magnitude occur much more frequently than powerful earthquakes of magnitude 8 to 9; the probability of a moderate earthquake occurring in the New Madrid seismic zone in the near future is high. Scientists estimate that the probability of a magnitude 6 to 7 earthquake occurring in this seismic zone within the next 50 years is higher than 90%. Such an earthquake could hit the Mississippi Valley at any time.

In 1811, the central Mississippi Valley was sparsely populated. Today, the region is home to millions of people, including those in the cities of St. Louis, Missouri, and Memphis, Tennessee. Adding to the danger, most structures in the region were not built to withstand earthquake shaking, as they have been in California and Japan. Moreover, earthquake preparations also have lagged far behind... ."

It really is a strange sound.

OK, here's an odd thought that just occurred to me.

Let's say we CAN write a small app that allows us to get the RAW data from the seismos around YSNP.

We then convert it to WAV files.

Then, using a good multi-channel mixing program (such as the amazing, and free Audacity), we mix the WAVs from a number of the stations around YSNP such that their apparent audio locations are approximately where they would be if we were in the center of the park or centroid of the station locations.

Through headphones, we might be able to "hear" where various EQs happened by the ear/brain's amazing ability to locate on sounds (like snapping twigs in the forest at night) by our ability to hear "first arrivals".

You know how you can always tell exactly where a noise comes from if it's got a nice sharp waveform to it? (Snapping twigs, hard objects hitting others, etc.) Perhaps we could "hear" a virtual representation of the earthquake swarm.

That'd be amazing and fun and perhaps, just perhaps, actually somewhat informative or valuable in a semi-scientific way.

Geogeek and I have discussed this a bit as regards rapidly showing one seismogram and then another so that you can pick out the "real" events from the bogus ones by letting the eye/brain integrate things.

Maybe it's equally valid to let the ear/brain do some of this analysis, too.

Anyhow, just a fun thought for a fairly massive project.

I am sorry, I am not up to speed on what I am suppose to see in the information you provided. Sorry, to be so uninformed about these things.

But what does that information actually tell us?

I really hope I'm not kickinga dead horse, or stating something obvious. But this GPS data is cool.
I am actually EXTREMELY interested in the data she had in the LINK she posted.

It seems the numbers have gradually changed throughout the years, from 1998-2009, showing obvious movement around the station. There is ONE noticeable spike in numbers, on Jan. 10th. 2008. 1559.9?

But what is the most interesting, is that the constant "rrr" being displayed actually changed to "ppp" on Dec. 24th. Coincidence? Then back to "rrr" ONCE with the 1559.9.

Thoughts?

YPP seems very prone to that sort of thing.

It may well be wind.

It's done that repeatedly over the last few weeks.
