Whats going on at yellowstone?

Well, that was cheerful.

Anyway... they don't update quakes under 2.0 on weekends, huh? So we probably won't see the vast majority of these showing up on the map until after the MLK holiday.

I continue to see little quakes on GEE but probably nothing we'll see plotted on the map. Guess we have to wait for the next weekly update for any actual word on what's happening in the park at large.

dont you mean their ever so annoying monthy updates? or that they only update the map of quakes weekly

They won't update earthquakes so quickly, at least publicly.
Until they have been reviewed twice (notice how each earthquake is "Version #2") they don't get added to the public list, but I bet internally they're already working on them.

Unfortunately the fact that some of the bigger ones have appeared in the USGS M2.5+ world earthquake list means that this process will slow down, as Yellowstone attracts the attention of many people around the world and the YVO doesn't want too much of it, especially for such minor earthquakes. They can't avoid showing M2.5+ earthquakes, but they will delay showing as much as possible smaller ones.

Note: this is just my speculation based on my observations of YVO's efforts over the past year. After the December 2008/2009 earthquake swarm and the enormous attention they got all over the internet, their disclosure policies must have changed. Of course, we "savvy ones" can still figure out what's going on by using programs like GEE and reading public webicorders.

Monthly, now, you are right. I haven't followed this thread closely since last January, but didn't the updates used to be weekly?

I'm sure you are right about taking a long time to plot the rest of the quakes. If you look at the YMR webicorder it's obvious there have been many, many more that aren't on the map:

quake.utah.edu...

(Although most look like they are sub 1 to 1.8 or so in magnitude.)

This is a very rough estimate of every earthquake occurred since 20:00 UTC. I have counted very small ones too (probably negative magnitude). Each violet box is an earthquake:

Based on what I see on the YMR webicorder right now, my hope is that someone has picked up the unit and is fiddling with it. Or, a big wind just came along.

That is my preferred explanation.

Edited to add: Oh it does look like that was just noise for a few minutes there. I've forgotten what that looks like, it's been so long since I've looked at these things regularly. I think there was a 2+ quake just before, though.

I can see a similar signal on YGC station, but it's far away from YMR, so it shouldn't have much correlation with that.
Stations nearby YMR don't have such signal, though.
Unfortunately YMR is not available for public data streaming so I can't check in detail what's exactly. I don't think it's wind though.

It's possible that it's a local flow of some sort. Maybe steam/pressurized water coming out from a previously obstructed conduit.

Is this what you are talking about?

There was a 2.7, a 2.6, and a 2.5, in that order.

We were talking about a different thing which was clearly not an earthquake.
By the way, another EQ occurred right now, it looks the biggest so far, must be M2.7-M2.8.

We know. (Dude, that was like, so 2 hours ago.) We're talking about what happened at the very tail end of a string of small quakes on the YMR webicorder, I think it was probably noise in the park somewhere, a series of vehicles going by possibly.

You were right, that was another big one. USGS says 2.7.

That's four of mag 2.5+ now. All around 6-7 miles depth.

Well here we are again, I have been thinking that it was about time we say some activity of interest, and whalaa... with all the recent activity globally I am surprised it took this long.

Oops. I hope this isn't anything to big.

My equake for firefox has picked up 4 earthquakes 2.5 or stronger in the passed 3 hrs.

Is this something to be worried about?

Actually not at all... unless you start seeing multiple M4.5-5.0+ earthquakes.
M2.5~2.7 earthquakes are still very small.
By the way, another M2.6-2.7ish one occurred as I'm writing.

Another similar one is coming in right now on GEE. I'll update this post when I get a magnitude.

I don't think any of us can say if it's anything to worry about any more than it was last year. Let's hope not. It is really disconcerting to see any earthquake swarms under a supervolcano, but these really are not big quakes. I am sure the geologists at the observatory are working on it, but we probably won't hear their thoughts until the swarm is over.





[edit on 17-1-2010 by quakewatcher]

Hmmm things seem to be indeed active, nice sized one just now, prob 2.5.3.0 also the smaller spikes on gee regestering on alot of stations proves to be not the wind, but smaller numerous earth quakes, i would not be surprized if we have seen over 100 earth quakes just today

Thought I'd re-join after being active on this thread during Yellowstone's swarms last year. My ears always prick up once I see little groups of 2+ being registered for Yellowstone.

What's the general consensus? Moon activity or is she chattering again?

This is worrisome.

Seems to be an awful lot of activity lately.

Watching....

Another

EDIT: Apologies, this one was posted just above... however USGS showing it as 2.6, not 2.5 as GEE showing..

That's still very tame compared to what happened on December 2008.

First day of the 2008/2009 earthquake swarm:
theinterveners.org...

Today's earthquake swarm:
theinterveners.org...

Note how much smaller are the earthquakes.
