Nothing at all. This is the one you put up earlier and I have put that big red spike sound file in the post above.

Off to QuakeWatch to see if the West Coast is still with us.

I see that it is only on one station which mean usually local - but it is so long and colorful that it makes me wonder what could be doing that - maybe the lake "thawed" all at once.

um, no, i take that back www.quake.utah.edu...

If you are talking about the bottom of the display around 19:00 UTC
I think it is possibly more of the Spring Clean-up.

I hope it is just spring clean up! Something to keep an eye on though. Okay, now that it has stopped and I have thread whip lash it's time to leave the office. - Glad I run the business!

thread whiplash

Ne too. can we try and keep old Yeller on the yellerston tread. That would be grand to be sure.

Spring clean-up I think is pretty much agreed then??

The audio is very similar to yesterday. It is interesting I think the
complete stops in the noise are probably coffee breaks and lunch.
We'll see if it starts up again, after a whilie. Some of the sounds
remind me of how a Caterpillar with a large heavy blade out at the
front are used. They quite often just drop the blade on the
pavement pretty hard, and I think that would really shock the
seismometer even though it is way down at the bottom of the
bore hole. The other thing that may make some of the noise
would be the metal treads, and the whine possibly the motor.

It is really hard to translate what we are hearing because being
speeded up like this, what is now audible were previously sub sonic
and the sounds we are used to are all filtered out by the earth
and the low frequency response of the seismometer.

A few years ago I used to pick up seismometers on a portable
scanner VHF UHF receiver. I could pick up the seismometer
telemetry. The seismometer frequency modulates an audio tone
so quakes sound like vibrato. When I hiked to some of the
seismometer locations in the local mountains, I could always
tell I was getting close because my footsteps made the tone
jiggle. I learned to recognize many sounds like cars and wind
with that system.

The QuakeData audio is a completely different sound experience
so I have to learn all over again!! It is great fun though.

There is a HUGE difference in the settings on those. One is a 125 micro Volts and the other is at 1600 micro Volts.

No idea how far apart these are but it sort of helps when you can see them in a gif, so here is one.



OK here is a different way of looking at it.



This is one laid on the top of the other but with the opacity decreased. Where the colours are heavier is where the two recorders have data, and lighter where only one has data.

Really neat graphics, and as you say a picture is worth a 1000 words

Where do you get the sensitivity settings?

Station IMW in the tetons has really been confusing me. Last
night I was trying to figure out where the quake at around
23:27:23 UTC was located. The southern instruments in
Yellowstone showed it, but IMW showed it at clipping level. Yet
the arrival time was not earlier. Then I found that that instrument
which appears to be a short period one, was not archived but
rather a broad band instrument was archived and the amplitude
was very low on that instrument.

Now that it has been posted we know it was in Yellowstone!!!

The sensitivity for those is on the bottom of the U of plots so not too difficult.

As for others you could try (as an example) this and then click on View RESP and that give you masses of information and to be honest I have absolutely no idea what it all is but it seems to be to do with sensitivity. May be you can work it out.

reply to post by PuterMan


Thank you for that. The print was so small I never noticed it!!!

The Quake of Mar. 17, 2010 03:25:10 UTC appears quite similar
to the 1.7 Yellowstone quake listed this morning.

On this map it appears to be about equidistant between
B208, YPC and YJC. It could be a tiny bit larger than 1.7.

www.quake.utah.edu...

It will be interesting to see how far off my guesstimate is,
when they post it.

I am beginning to appreciate the work involved in checking
small quakes, for location and magnitude.

think about that cloud that comes from a volcano. The one that knocks over trees and buildings and anything else in its path. It would be horrendous.. I try not to think about it as i live on the western side of MT

reply to post by hesphastus


Well, one good thing for you to think about in the event of a major eruption - if it were to occur in your lifetime (which I highly doubt) - on the up side - you wouldn't have to think about it long - sorry to say, you'd be toast - so, if you choose to live in such an area, do not worry about what may be some day - which is highly unlikely - focus on now! Or, you could move away from something so majestic and humbling to a further place - out of immediate toast area - and have to deal with that. I myself if I were not the nurturer - , would take toast - but that is not my nature -!

Nicely put

We choose to live where we are but the Alps' beauty comes with risks! You can't dwell on it but do educate yourself, be prepared, be vigilant but, most of all, as Ann said, live life to the full

Well PB B208 is cracklin right along. Seeing as how it is 1:00 in the morning, I'm thinking it isn't due to road work!

reply to post by westcoast


I am assuming here that you are somewhere where 08:00 UTC is 01:00 in the morning otherwise 01:00 on PB.B208 looks quiet.

I would say at a guess that most of that is wind noise as the wind does affect the plots, especially if the area is wooded. There are two reasons for that which are (1) the actual pressure of the wind has an effect on the ground and can rock it, and (2) in a wooded area in addition to 1 the roots of the trees can rock and cause waves on the plot.

I am answering as if you don't know this, however I suspect you do, so my apologies as this is directed at those who may not be aware of this.

I shall see if I can identify the quakes between 10:00 UTC and 13:00 UTC as I suspect they are not local.

B208.PB..EHZ.2010.077




[edit on 18/3/2010 by PuterMan]

Starting at 15:16 UTC is a series of different looking quakes at YPP
which show up on YLT, B944, B207, YPM, and even down on IMW.
Any thoughts?

Edit: here is a sound file of the sequence.

Has anyone else noticed what seems like a complete lack of activity with old faithful this past week? Now, I don't live in the park and I don't spend time watching the life video, but by going back and looking at the seismo graphs it appears that there hasn't been a detectable release since the nice sized quake on the 12th.

Am I wrong? I don't live in the park and don't watch the live video much, so I am just basing this on the charts. Take a look:

thumbnails

Start with the twelth and work your way up to today. If you go look at previous dates, you'll see that the venting seems to show up about twice a day...once earlier and later. Since the 12th though....nada. There is some noise right now, but that's showing on a nearby station also, so I'm thinking it is more road work or, well.....let's not go there again.

alot of this is hype to say the least and fearmongering to say the worst

keep in mind the earth is always shifting and tectonic plates are alwyas moving. the number of quakes is not indicative of anything unusual except its normal cycle of variation which can be tracked through the records. just like your chest rises and falls with breathing so does the earth, and your chest doesnt just explode after panting from running a quarter mile does it?

Ummm....I respect your opinion, but I think to say that to monitor and question changes in this caldera as 'hype' is not the most intelligent statement I have read on here.

I agree that there are 'out there' comments randomly on this thread that are obviously from people who live on the fear. But for the most part, it is well-thought out and sometimes darn impressive scientifc info gathering. (I am not the later obviously, but a casual observer)

All input is welcome.....but my personal opinion is that I live close enough to this monster to have a heap load of respect for her and it is a hobby of mine to observe/learn. To turn a blind eye and say "oh, all this activity is normal therefore I am going to just ignore it"...is not an option for me. It is a magnificent place and the whole point is that no one really knows what normal is for Yellowstone, it is so acient and we are so young. It has been there for millions of years and we have monitored it for less than 200 years. How can you possibly say what is and what is not 'normal'?

I respect Yellowstone and am fascinated by it. I observe because of that respect, not fear.
