Whats going on at yellowstone?

I thought you folk might enjoy some slightly different pictures of Yellowstone.

Not exactly your normal tourist brochure type.

are you kidding those pics are all awesome the best iv seen of YS yet..

Those pics are amazing...I haven't been to yellowstone since I was probably 13 and I still remember getting carsick at Bear's Tooth Pass...it is crazy how beautiful it is there...I had forgotten about that.

Wow Guys check out this llast huge signature. Just happendly to

Guys this is really crazy there goes another one plzzz

You're watching the YMR webicorder. It's really sensitive. You need to cross reference. If you see something on one webicorder and it's a quake, it will show up on other stations. These stations also pick up earthquakes from other parts of the world. So if you see one, then you need to check the worldwide quakes to find location.

Trust me, you'll know when something is really happening on the webicoders when someone posts a notice or is alerting the others to something happening.

The best thing you can do is research siesmographs and learn how to read them. Local quakes have a very pronounce begining. If you go through many of the pages on this thread you will find lots of quakes posted and you may be able to figure it out from them.

Yellowstone has been quiet. Real quiet. So relax and watch to see when someone posts quakes.

Thank you Robin - when someone starts another thread on Yellowstone I get a little nervous.

That was something I was pondering earlier today --- Yellowstone has be toooo quiet. We had the uplift over the past years - now - flatline. in all directions. Since last years swarm, very minor swarms (which, is really, not normal) There are always quakes in the park, mini swarms, larger swarms, ups and down, -, -, but --- it has been almost eerrillllyyy quiet - shhh. But who had said it over at YVO I think it was that I remember, - When We don't see activity is when we worry?? Am I remembering that correctly? -- I feel that way anyway. She seems in a soot of hover state, her preasure was about to pop, she's maintained her blood preasure at a high rate - but, something has got to give soon

I just figured out that the webicorder might be more sensitive than the seismographs around the globe, so when I saw those large spikes I was like woah. It really frightened me. Espeacially since I haven't seen anything like that for a long while on the webicorders. One question though, I only see one quake posted on the RSOE site what happend to that second spike. I figure its a similar magnitude, but was it at the same depth?

sweetie , its obviously the calm before the storm..

and i agree with you SHES BEEN TOO QUIET.

i wouldnt go by Reso their a bit behind on the times .. and more times then not their wrong.

Too quiet - now I'm concerned again.

I'm really sorry about that little incident back there though guys. I guess I got over exited because I suspected another one would strike after the quake at 18 mst considering the webicorder pretty much flat lined after that and didn't release any short bursts of extra energy. That and the fact that they both looked larger than most of the quakes I see on the webicorder these days.

YS`s too quiet period can last for years .. i wouldnt worry

reply to post by shikori


no worries we have all made mistakes ...

it takes time to get whats going on if anything and to understand it all..

I have but a sound byte on your thread and said that these were not actually earthquakes.

You may find it useful to work through this........

Why False Positives?

Tin Foil Hats Off (for a moment Folks).

Having, at least as far as I am concerned, found a satisfactory explanation for the recurrence 47 times of the "set of 4", I would now like to offer an explanation as to why these earthquakes get added as 'false positives' in the first place.

This all relates to the 'false' 2.4 at 14:48 UTC (8:48 MST) on 08 Feb 2011

This is the quake in question:
Date/Time UTC,Latitude,Longitude,Magnitude,Depth(Km),Location
2011-02-08 14:48,44.67310,-111.18000,2.4000,10.0000,western Montana

First take a look at these three slices of seismograph display from 3 recorders (Courtesy of the YVO)
YMC

YHB

MCID


Note that there is a gap in transmission on all three recorders at the same approximate time.

When the signal dies the computer is looking at zero. Why does the signal die? This is the telemetry problem that I have spoken about. Ice and snow build up on the equipment causes these.

YVO:

As indicated earlier, the problem is ice and snow build up at the main telemetry node where all the data are gathered and put on a microwave tower for transport from the Henrys Fork area (outside the park) down to Salt Lake City.

Those of you who were around last year may remember an extended 'blackout' due to problems in this area.

Here is MCID around the time of the false positive. I downloaded a 30 minute 'slice' around the time.

The circles are telemetry spikes, and if you dive in deeper you can see more of them.

On the next one I have zoomed into the trace a bit, around the time of the FP and you can see myriad small spikes. (Some of these are telemetry errors and some are parts of the waveform.)

If you are a computer and you are looking at zero signal, and then it pops back up when the signal returns, this can be interpreted as an earthquake. This would especially be the case if the signal was reasonably high (wind, buffalo farts etc) when it came back on.

YVO:

Moreover, since the data problems differ slightly for each station, that results in a very "locatable" phenomenon for the computer. It would be possible to filter out this "bad behavior", but would result in slower response time (a no-no for seismic networks) and possibly some missed earthquakes.

As I said a day or so ago it is quite clear from my records of deleted quakes that these happen much more frequently in the winter months, and to a degree as an inevitable consequence of a large swarm.

In addition the YVO said:

Eventually, when the park receives another T1 line at Mount Washburn, we will get everything on the internet directly, and the system will improve (and be more redundant to problems).

(A T1 line is a broadband internet connection for those who are not aware.)

A most important fact has come out of this that what we see is not the detailed scientific record, not that I suspected it was.

YVO:
quote]If you look at the public webicorders for 2/8, you won't see the small data gaps below, but you will clearly see that there are all sorts of spikes from telemetry problems, especially on YMC and MCID, two of the stations that caused the earthquake to be picked.

I have no problems with this as a very reasonable explanation. You may resume wearing!

/End Tin Foil Hats Off

If you look now, there is something possibly brewing. A few small quick hits near YMR.

Question

What kind of quakes are those at 20:15 UTC?
