Whats going on at yellowstone?

I'm surprised no one else has jumped all over this yet!

The park is really rockin today.....the 'ole 'double-tap' seems to be starting up again.

Well, because technically that is not in Yellowstone Park. I saw it, and made a mental note of it. But honestly, I don't think you can equate the "double taps" we were seeing during the swarms with this. Different place, different animal. Just my .02, but observe on please.

Strong signal.

Magnitude 3?

near Yellowstone.

Huuuui, The earthquake has shaken the chamber. ;P

reply to post by Austria


'shaken the chamber' is a VERY good way to put it. Have you looked at the seismos for the park? Holy smokes!!!

Check THIS out.

TrueAmerican made some good points in response to my last post, but I will stand by what I said I think. Looking at it again today I see once more the 'double tap' features. These larger quakes may not be in the park itself, but I am feelin that they are most definately connected!!

When I look at the seismograph, I think that the epicenter was in the park! Not outside. What do you think?

reply to post by Austria


It is certainly close.

*GROAN*....another sizable one is just showing up. Not on USGS yet.....


Just showed up. another 4.0!!!! Oh man....

Definitely worth keeping an eye on I'd say.

There appears to be quiet a number of quakes according to the instruments. Those will most likely be added sometime during the week as they appear much small - - so far something is brewing!

reply to post by Anmarie96


My friends...this is giving me a bad feeling in my stomach!

Those 4.0 are big uns for this area, especially so close together, and yes...there are numerous quakes just not quite big enough to get recorded automatically.


THIS siesmo is SCARY!!

I'm not saying that there is an erruption pending or anything of the sort...just that this action is noteworthy of a possible event of some sort.

When were the last 4.0's in the area?

Here is a good MAP of the area, showing the proximity of those quakes to the park. (it's also a good link to the UTAH siesmo network)

Good question on the 4.0 quakes. I'll try to look it up!

reply to post by MoorfNZ


We had a 4.8 in the area along with few hovering around the 4.0 mark in mid August. I do not have access to that data at the moment. This area, while does have quakes, the larger events are not typical. We have just had 2 separate events of the same approxiamte mag. - I am thinking we are not done here and expect a larger quake very soon. (wish I didn't feel that way - but that's MHO)

Sorry, very busy trying to get the program finished. Difficult to know which blend to use as most of them make it very difficult to see. By adding the two maps as well you can see that the circle does match the low velocity zones, as one would expect perhaps?

reply to post by Anmarie96


Well, on the Utah website, I found (list off to the side on main page), there was a 4.8 in August outside Jackson Wyoming. Other than that, there was a 4.1 in March of 2008 in the park.

There have been a few near 4.0 this year in Utah...but that is all I can find so far.

I have the same feeling too, that this is the begining of something, rather than the end. Take a look at the depth. Around 6.0 km...just the right depth for the chamber.

Edit to add: Or perhaps I should say PLUME rather than CHAMBER based on the newest info? I think that would make more sense...if these quakes we are seeing now follow the plume???

Well, it appears we may have a small swarm happening here, as I have tracked these down in GEE. And we've got continual micro activity happening now, very much resembling the Yellowstone swarms we've seen before.

Now curiously, The USGS did not use the closest station to these quakes in their phase data. They've got IW.SNOW listed as the closest station at .4 degrees, when in fact IW.REDW is closer at .29 degrees. And that station is not even listed at ALL in their phase data...very strange.

But I'm watching all of IW network in GEE, and we've got continual spikes going on, beyond the two mag 4's. They are small, but active. I have long said we need to watch south, lol, I just didn't mean this FAR south. Most curious indeed.

reply to post by PuterMan
Awesome, thanks,.
interesting I think.. Good reference points for me..

reply to post by TrueAmerican


Thanks for the info. I remembered someone saying that South was the direction to keep an eye on, I just didn't remember who.

Why do you think USGS would do that? I mean, it has been reviewed by a seismologist so you would think they'd update the stations if incorrect. What would be the point?

I'm also curious about the plume theory circulating right now. Do you think these quake are just explained by the fault line, or could there be a connection to the plume? To me, it would then make sense why we are also seeing this swarm...just thinking out loud!

reply to post by westcoast


Well, there have been theories that the magma plume is finding other exits that are going outside the park. And it is possible we are witnessing another here. Remember, these are EPICENTERS, meaning the point on the earth's SURFACE directly above the hyopcenter, where the quakes actually happen inside the earth. But the shallow depths of these quakes at 5 and 6 km are consistent with where the top part of the plume is thought to exist. So that would lend some credence to another "magma exiting" theory.

reply to post by westcoast


Nothing to be concerned about.

Take a look at that post. It shows the 4.8 in that bunch. This is just pressure release connected to the previous events as far as I can see. If there is a fault line there then you would expect to see a progression down the line as each section adjusts.

Here are the seismographs in relation to that lot.

reply to post by TrueAmerican


Thanks for putting that into better words.

I'm trying to pull up the nearest stations on GEE, but I'm having problems getting anything outside the park to load. Having said that, I'm seeing lots of action there, like you said, including a sizeable one about 15 min ago. It must not have been about 2.5 though, since it isn't showing on USGS. (although that doesn't seem to be as reliable as I once thought)

Also an interesting note: The deep tremors stopped a couple of days ago here in the PNW (although there was still a small flurry yesterday). I theorized a short time ago a possible connection between the lack of action in the park correlating with the start of the deep tremors and whether we would then see an increase in action at Yellowstone when the tremors stopped. Hmmmmmm........
