Whats going on at yellowstone?

Can anyone give me their thoughts on what is going on here? Harmonic Tremor?? Kind of appears that way to me - Hope I'm Wrong! www.seis.utah.edu...

more to the point has anybody noticed that the acting scientist here is the same guy from the AVO Peter Cervelli, unless the usgs has more then one guy with the same name and same email add? i just find it odd but interesting kind of odd. what happended to Jake Lowenstern.

Jake is still scientist-in-charge of the YVO. He's simply out of town, it seems; that's why the press release says Peter is "acting scientist-in-charge." Peter obviously moved from AVO to YVO recently. He was even at the HVO for a while, too. Reassignments happen. Nothing to see here...

Lets check our history books and see if the largest swarm ever recorded was affected by the moon.

It started slowly on Oct 85 after a few minor quakes over the first days. The action really picked up on on the 12th, in three days on the 15th the moon was at perigee and there is a peak of earthquakes. The quakes continue for a few weeks at a lower intensity. This lasts until Nov11/12 when there is another spike in activity. November 12 1985 had a new moon at maximum perigee. November 12 1985 had a total solar eclipse as well. At that moment Yellowstone was experiencing a spike in activity. The quakes carried on for many more weeks in decreasing intensity.

The swarm of 1985 happened when the caldera was at maxium uplift. The earth was closer to the perihilion. The moon was at it's closest perigee and near it's maxium apogees. During the whole swarm of 1985. The moon was playing an active part with it's gravity on earth. A New moon at closest perigee, a solar eclipse, followed by a full moon near maxium apogee and all the while Yellowstone was having a swarm. Coincidense?

In 1895 Yellowstone's caldera was full. Of hot molten magma, a liquid. The moon moves oceans of water.

In 2008/09 Yellowstone's caldera was reaching a maxium uplift. Full from a massive molten injection the size of Los Angleas a few years before. The moon made an exteme trip around the planet and shook up the molten mass of red hot liquid. In 2010, one year later, the caldera still near full, the moon made the nearly same extreme cycle and the same thing happened. Another swarm.

Enough correllation for ya. The moon was in a dynamic orbit on all three occasions. And the other swarms don't compare much to these. Wrong seasons, wrong areas of the park, and smaller sizes when the caldera wasn't near maximum uplift.

Not all swarms are created equal.

read back about ten- twenty pages, much discussion about it.
it's not harmonic tremor, YMR always noisy. snowmobiles, roads, and could be geyers. it's always been active like that.

Funny, it's getting near late evening and things are picking up again. Another 30+ soon to come. I would be arriving on schedule if it did.

Ever wondered what a quake swarm at Yellowstone does to a web server monitoring it?

It's good seeing such interest, though, I like it. Let's see how long it takes to taper off...

So what do you all think of the 3.6 quake just south of Yellowstone, the 3.0 SW in Utah and all the 'noise' on the webicorder? I don't think it's just local (ie snowmobile, truck)...because now it's starting to show up on the other stations, and it's way past dark.

Interesting!

Well, I for one have been keeping a weary eye on Teton anyway, because of recent sporadic activity at stations like FLWY. I immediately tracked that quake down to coming from south of the park, with the highest and soonest intensity occurring at station LOHW. That is corroborated in the phase data from USGS as correct- for being the closest station available to the quake- which occurred slightly east and to the south of that station.

I have also been researching those signatures on YMR, which I raised the possibility could be HT's, but I think I have finally convinced myself that they are not HT's.

As it turns out, while I was correct about station YPM being closer to station YMR than station PB.B207, it appears that station PB.B207 may actually be slightly closer to where this swarm is occurring. YMR and YPM are still close though, so all the data from those three stations is particularly useful in gauging whether those signatures on YMR could possibly be HT's.

So I was finally able to track down the webicorder graphs for PB.B207 on 1/23/10 through the use of the BUD data system. When compared to YMR, those signatures did not appear at all. Given the close proximity of these stations, I am led to conclude that indeed those signatures must be man made, because simply, they are not showing up on PB.B207. A HT that close to PB.B207 would almost assuredly show up with a very similar signature, and it did not- so there's my answer to that- No harmonic tremors today folks, or yesterday for that matter.

You guys can try this url for the PB.B207 webicorder for 1/23/10, just not sure if it will work, as you may have to generate this yourself from the BUD system:

PB.B207 for 1/23/10

Someone let me know please if that link works for future reference, thanks.

My hunch for the day: watch south, near Teton for the next few days- something might be brewing there.

Link works!

Thanks for posting that. It's a pain to pull up GEE just to check in from time to time on that station.

I can't even find that station. Maybe I don't have enough patience!

It is much more dramatic though..where is it in the park?

PBO's B207 is 4.5 km SSW of the YPM station. 44.619 degrees north, 110.8485 west.

Edit: did I say SSW? I meant SSE... sigh.

Here's probably the easiest way to call it up, to light it up on the map:

In GEE
1) Edit>station chooser, while displaying the map.
2) Add network
3) While you wait for networks to come up, select vertical only and "extremely short period"
4) When networks load, add network PB. (Plate Boundary Observatory)
5) Scroll down and find PB.B207 in the list, and it should be lit up in blue, showing you have the right channel selections for that station.
6) Simply select it in the list to light it up on the map, and then Load Real Time Data.

7) Observe fireworks.

ETA: Also, that station displays in nm/sec for smaller quakes and microns/sec. for the bigger ones. It is one of the few EHZ stations I have not seen saturate out at 300 or 600 nm's. Just keep in mind it is real close to the swarm, so everything reads big there. ~1 micron per second quakes there are not even showing up on USGS, so they are still relatively small. If you see 20 or more Microns/sec though, you probably got a 2.5+.

the link works for me..

2nd line

Depending on the station, BUD data generally lasts for about 7-14 days, then it gets archived.

PB.207 data however, goes back to November 2009, so probably it lasts two months.

QUACK link

A rather large sized one occurred just now.
Must be above 3.1-3.2...!

Okay, the wierd thing about this quake.....it may be a very large one somewhere else, or something else is going on.
Looks like it was a series of two quakes...maybe a for-shock?

There aren't any signs of this swarm slowing down or weakening.

However my firefox app for quakes is not reporting any

Another biggie.. gotta be 2.8 - 3?

Again, not been reported by eQuake

Now that the graph is coming together, I'm thinking it is close to 4.0, and maybe it is just showing up this far away. (nw washington seismo) It has to be at least a 4.0 though, or else a much larger one somewhere else.

I'm "listening" to the traces right now...
There definitely were three earthquakes, as this spectrogram from YMC station shows:

The third one was the strongest (the maximum amplitude here is clipped but you can see that it lasts more time than other ones)

Okay, I don't know how good this is going to look, it's a really big capture, might be crap... but notice how the start times on each of the little waveforms don't line up? That indicates it was local, and the one it shows up on earliest (B207) was the closest to it. USGS says mag 2.5 now...

Yep, it's crap. Dunno how to get scrollbars on it... the right-hand side was pretty interesting. Oh; right-click on it and view it by itself, that looks okay. ish.
