and poof! its gone

is that the second 3 they've deleted today?

BG - did they make this one go away to? I'm not seeing that now - they did this earlier as well.

Here is the new mag. reporting - pay attention and read between the lines - it's for us and to see how we handle it (I think) Either way - this swarm is larger in mag. than more recent ones.

Beginning today (October 1, 2010), the University of Utah Seismograph Stations has reduced the magnitude threshold for public web posting of automated earthquake locations and magnitudes for the Yellowstone region. The new minimum magnitude threshold is M 1.5, reduced from the previous threshold of M 2.5. The new threshold value will allow more earthquake information to be rapidly released to the public and other users. This lower magnitude threshold will be tested during a trial period and may be increased again.

and this to be taken highly into account - An Announcement from the UofU

Small earthquakes are common in the Yellowstone region. With the reduced magnitude threshold for web posting of automated earthquake locations and magnitudes, it will no longer be practical for seismologists to continue the practice of reviewing all of this information immediately after posting. Users of these data should be aware that an unreviewed earthquake report can be significantly in error and might even be a false alarm, regardless of the reported magnitude. The University of Utah Seismograph Stations will continue its policy of including only reviewed events in its finalized earthquake catalog.

Sorry about that - some reason you can't paste the whole thing - here is the last paragraph

and BG u updated while i was messing with this freakin computer

that is strange did they give a reason.
I just noticed the RSOE site if this is the same one they still show it as an earthquake.

hisz.rsoe.hu...

Yes, the other was a 3.4. As I said before, it does not make sense that they reviewed small ones but the 1.8 on the 16th and the ones today have not been reviewed. They are all kind of phantom quakes if you ask me. The one on the 16th had no signature and these today are showing nothing like they should. But, why are they left on so long? I don't post much but I have a vested interest....12 year guide in the park. The only change I have seen in the last 3 years would be 1 certain geyser in West Thumb was more active.

Yellowstones always scared me the most for the likely candidate to cause our extinction. It erupts on a 600,000 year cycle and its last eruption was 640,000 years ago. Eek.

23km deep! This are NOT the typical swarm quakes that we see....and I still didn't catch this on GEE...but I think that's because it's so deep and the ones nearest are all screwed up. I don't like this....

I bet it will be deleted immediately.

Holy cross-posting batman.

I guess a lot of us are watching tonight.

HA!!! We all posted at about the same time.


Something is going on you guys, and it isn't typical. 23 km deep?!! I have GEE open as we speak and all I'm getting for the ones nearest are those wierd lines....

Why no abnormalities are seen on the seismograph?

Be still Yellowstone! I want to sleep!

EARTHQUAKE DELETED. hahahahah

I'm going to sleep. That should do Yellowstone as well.

Okay, so I pulled up every station I could in GEE and then closed out the messed up ones. I am left with a few good ones...and I think I finally am seeing a quake come through. We'll see if it registers. It's not big..probably 1.0 or so.

Best ones are WY.YDC and WY.YGC

Folks - relax - yes I agree there is something amiss - but ----- as I posteded earlier from Uof U

"Small earthquakes are common in the Yellowstone region. With the reduced magnitude threshold for web posting of automated earthquake locations and magnitudes, it will no longer be practical for seismologists to continue the practice of reviewing all of this information immediately after posting.

Even though these quakes are deep - they should still be showing up more so on the instruments - - unless they have been down tuned.

Thanks to all of you knowledgeable for keeping us novices up-to-date on activities at Yellowstone Park. Let's hope she's just stretching and not ready to get up yet. *go back to sleep*

Doing my own research I ran across this vid series about Yellowstone. Don't know if it's been posted before because there's no way I have time to go through the whole thread.

Nature is super amazing,

Star

Yellowstone is not yet erupting, we would see first fast rising of caldera, pressure makes it rise. In 2009 it looked like its gonna blow soon, because fast rise, but now its actually slowly going down. But its still much more higher than it used to be, highest point was early 2010.

pboweb.unavco.org...

And that swarm seems to be over, maybe just faulty equipment. Maybe strong snowstorm affected them.

Wow, I'm so glad that I discovered this thread, I'm obsessed with geological occurrences within Yellowstone. It's always been so amazing to be how something so beautiful has the potential to be the largest natural disaster since the extinction of the dinosaurs.

Okay folks - I was wondering if anyone other than myself had noticed this here on the Thread - been waiting for days here now - and - no one has brought this to light - so - I will. :-)

With regard to this latest little "swarm" (which didn't really happen - although it got a buzz didn't it :-)) that showed up on the USGS USA Map - did you notice if you clicked the World map and zoomed into Yellowstone you get = Nothing - Nodda - Zippity Do Dah.

Could that be because none of the quakes (real or otherwise) was above 4.5 mag and therefore not on the World map?

World (Magnitude 4.5+) it says above it.

No, the states always pull up all mags no matter which map you pull up. - try it (excluding this last malfunction at yellowstone).
