Odd - or not ? First big snow storm of the season has triggered? a few quakes?

? - they just removed it - maybe a plow hit the tree the instrument was on?

Hmm... In no seismograph is a shock to see...

Morning (um,,,afternoon) you guys! I am finding this all rather strange.

Look at THIS map, that is getting lit up with current and past quakes. Now look HERE at the park seismos.

Is it just me, or do they not add up? I mean, yesterday they were a mess and today a couple still are. I attributed that to the weather. But I would definately expect to see a 2.0 mag quake on there.

According to this list there have been 4 today at or near 2.0:

1.9 2010/11/19 12:13:24 44.467N 110.553W 1.1 49 km (30 mi) ESE of West Yellowstone, MT
2.0 2010/11/19 11:48:13 44.557N 110.950W 16.8 17 km (11 mi) SE of West Yellowstone, MT
1.9 2010/11/19 11:27:43 44.334N 110.642W 5.2 52 km (32 mi) SE of West Yellowstone, MT
1.9 2010/11/19 09:12:47 44.306N 110.605W 6.8 56 km (35 mi) SE of West Yellowstone, MT


I am only seeing a faint semblance of them on a couple of those seismos though. Note the depth? The biggest one is a whopping 16.8 KM deep. That is wierd too. I pulled up GEE and most of the stations are giving me a wierd interference again, like last time. Maybe the weather has something to do with it, but it's bothering me. It is about impossible (for me anyways) to get any kind of a clear picture of what the activity is there right now.

Okay, so I have just watched two quakes come through on the EQ list for the park:

2.1 2010/11/19 13:10:04 44.336N 110.711W 14.4 48 km (30 mi) SE of West Yellowstone, MT
1.7 2010/11/19 13:03:48 44.632N 110.638W 12.6 37 km (23 mi) E of West Yellowstone, MT
1.9 2010/11/19 12:13:24 44.467N 110.553W 1.1 49 km (30 mi) ESE of West Yellowstone, MT
2.0 2010/11/19 11:48:13 44.557N 110.950W 16.8 17 km (11 mi) SE of West Yellowstone, MT
1.9 2010/11/19 11:27:43 44.334N 110.642W 5.2 52 km (32 mi) SE of West Yellowstone, MT
1.9 2010/11/19 09:12:47 44.306N 110.605W 6.8 56 km (35 mi) SE of West Yellowstone, MT


A 1.7 and a 2.1

I have GEE open with 8 seismos open. Four of them are messed up with just spikes registering. Four of them are working. While they are a bit noisy, they are NOT showing a mag 1.7 or 2.1 quake!!! I just don't get it. These quakes are coming in from all over the park too. I wouldn't think that USGS would be messing up and recording snow plows are anything...and if they were, they would be showing up on GEE too.


EDIT TO ADD: I just noticed the depth on those last two: 12.6 and 14.4 km. Is it because we are so used to seeing shallow quakes, that it isn't registering as much? What do you all think is up with these deeper quakes spread out? Are we looking at a fault line....this would be running UNDERNEATH the caldera. OR, if you subscribe to the PLUME theory, than it could be a whole different beast!!

There is definitely something going on here! I am not quite sure yet what it is and am unable to search to much as it is a very busy day at the office. - Start Vacation tomorrow (ya that's a laugh get a whole 1/2 day i'm sure) I have noticed that not only are quakes appearing and then disappearing in the park - but all over the US as well. I am wondering if they are doing some sort of maintenance with the USGS system.

The smaller deeper quakes - I would image, would show up smaller on the instruments.

I noticed that the 1.8mag on the 16th has never been reviewed and was also one that I found no signature for anywhere on the seismos. If you look the 0.7's and other microquakes have all been reviewed up until this new flurry. Why no review on larger no signature quakes but review the small ones? If they are not quakes I wonder why they leave them up. The 3.4 was taken off quickly today.....someone must be watching the store.

Yeah, seems like Yellowstone is shaking after long time. Even Lake webicorder what is usually pretty quiet shows lot of activity. Some webicorders are messed up and its shame we can't see live webcam.

I by no means am anything close to being a geologist or a volcanologist or any other kind of ologist for that matter, but I recall reading somewhere farther back on this thread that there isn't anything to worry about until you start seeing a spoke like pattern to the earthquakes in the park. Well, if you look at the pattern of these current quakes, they seem to be spread out in a spoke like pattern throughout the western half of the park and just a tad larger than usual. (not that 1.9 and 2.0 are large quakes) I am sure it means absolutely NOTHING though. I just thought I would point that out....

Oh, and by the looks of the pattern they seem to be radiating out from the far western magma plume!

We turn to our resident experts, Puterman, ressiv, westcoast, anmarrie96 and all the others that are in "The Know" about these things to see if they might be able to shed some light on this? Hmmmm?

Cheers!

WHOA! Check the USGS for Yellowstone! All of those popped off at once almost! And ALL over the caldera.

I have NEVER seen this type of event. (Where there are multiple small mag. quakes all around the caldera at the same time---its always a mini-swarm all in the same area)

I have to admit, when I looked at it, I was somewhat concerned. But what the hell are the actual odds of YS going off in our lifetimes, you know? But wow.... Hope to God it isn't waking up.

I remember it too, way back in the thread.....but I guess its something worth keeping ours eyes on, even though I don't live anywhere near the States, let alone Yellowstone...But if that thing goes "Chuck Norris" on us, the whole planet will feel it....Hope the experts in here can gives us some real reasonable input on the situation....

We have to keep in mind also that They lowered the threshhold of the magnitude which they now automatically report. So, in the past these smaller quakes did not show up right away if at all on the maps and eventually made there way into the list. So with that in mind just relax and let us see what transpires. Yeah - so much for my vacation (Opening day of deer season in my neck of the woods tomorrow - yum, yum - was suppose to have the whole week off) - Yellowstone has precedence

YPP is a very interesting webicorder to watch today.

quake.utah.edu...

And even more so, MCID:

quake.utah.edu...

and you can also see some of the same activity at YLT

quake.utah.edu...

That kind of thing on one instrument, I might dismiss as a malfunction. But it's too consistent in too many places. (Well, coupled with the acknowledged earthquakes on the map!)

I agree with Annmarie though that it isn't necessarily anything more than another interesting swarm. Watching Indonesia lately has been instructive of what kind of shenanigans can happen in the vicinity of a super volcano without it actually seeing any real activity. Imagine if we had this kind of online real time monitoring at Toba? The divorce rate at ATS would skyrocket

I got home and checked the most recent map. I freaked because it looked like the caldera was about to come unglued. But I checked the webicorders and it doesn't show any real activity, except for some very recent stuff around YPP. So it would seem that something is wrong with the computer updating the most recent map. Something doesn't jive.

OMG - LMAO - isn't that the truth - 150 points granted

So now the question is - does the weather really play a part or not?

Oh - and 1 star
