Whats going on at yellowstone?

At the time I'm writing they've added three more earthquakes, now 57 in total. I think they still have to add those between yesterday night and today's early morning.

Yes, they certainly did add - because there's on 64 Km and that definitely wasn't there before.

Now I have seen iris and the USGS go back and change EQ listing before.. but not at this magnitude and frequency.

One thing is for certain, with the changes to the list going on... the guys that deal with this stuff for a living are hard at work.

You have to remember not only do we look at these lists as outsiders, the professionals use these databases to piece together what is actually going on.

So we can look at it as they are on the ball this weekend after the holidays.. or its actually even more confusing for them.

I've been reading this thread since the beginning, being a regular watcher of the usgs earthquake sites (I find geology interesting).

There are some things that I found that haven't been mentioned yet.

neic.usgs.gov...

There's two graphs, one showing '90 - present and one showing 2008. The star in the middle is one of the 3.0+ quakes from today. If you look at the top graph, it shows that there HAVE indeed been quakes in and around the lake since 1990. In my research I have yet to see a SWARM like this, and have yet to see so many within so close a range of each other.

But some people say there have never been quakes in the lake itself, that is false.

IMO, magma is moving around down there and causing some minor problems. If scientists aren't talking about major short-term (on the matter of days or hours) uplifts or surface temperature swings I think we're ok.

Then again from what I've seen, something like this doesn't really have an analog in our time. It could go all at once, partially over a couple eruptions, with some major pre-quakes, some minor quakes in swarms like we are seeing now, or without warning at all.

There's really no use using the quakes alone as predictors. Now if someone came on and said the ground has risen 3 or 4 inches in the last couple days, then I'd hit the panic button.

Yes, something is going on - they are adding them -

just went to 60 -

er make that 61...

Do you think they're adding smaller ones? I see two .9

and a few 1.__ maybe they weren't there before? And we didn't notice?

Certainly the 3.9 was not there this morning though. That I would have noticed.

Im from Scotland, so have no real EQ experience. I have to say I have been strangely captivated by this thread and have to add a huge well done to everyone that is contributing to it. Your experience and knowledge is there for all to see.


Well done.

Respects

referring to the no quakes in the lake part... I don't really think anyone meant no quakes at all in the lake... there have been.

But, there have not been any recorded "swarms" in this particular part of the lake.. at least not in the usgs archives they have. The fact that this area is the one that has had the most uplift change in recent years is what makes it intriguing.

Glad there are more people who keep up with geology looking in.

This site is now calling it a Volcanic event with over 250 small quakes!!

Hmm... look at this map of 1998 quakes:
www.quake.utah.edu...

But still, it doesn't tell if those in the lake were in a swarm or not, somebody who's *really* motivated should try to read the written data and tell:

Well, someone "official" is acknowledging that this is unusual

CHEYENNE, Wyo. (AP) - Scientists are closely monitoring more than 250 small earthquakes that have occurred in Yellowstone National Park since Friday.

Swarms of small earthquakes happen frequently in Yellowstone. But Robert Smith, a professor of geophysics at the University of Utah, says it's very unusual to have so many over several days.

The largest tremor was Saturday and measured magnitude 3.8.

Smith says it's hard to say what might be causing the tremors but notes that Yellowstone is very geologically active. An active volcano there last erupted 70,000 years ago.

hmm the doctorsare working with the EQ's the 3.8 is upgraded!

3.9 2008/12/27 22:15:56 44.502N 110.366W 0.3 61 km (38 mi) ESE of West Yellowstone, MT

seems there's some panic there... not knowing wat to do with it...we can expect moor upgrades..

[edit on 29-12-2008 by ressiv]

Yea I've noticed the same maps too. I know there's data on all historical quakes out there, I just don't have the time at the moment to sift through the historical data.

Even though I am REALLY curious if swarming has happened before in that spot.

*sigh*

Time to grab a 12 pack and start researching.

Gotta love days off

250 quakes?
didn't notice them on the lists!
maybe they were

Anything less than M1 aren't on the USGS lists.

If that's the case, then there have probably been close to 150 or more quakes in the area under M1.

That makes this even more interesting (more quakes = greater frequency = more activity???)

[edit on 12/29/2008 by Fiverz]

Asking again...

Is there someone who can give a professional opinion on the current data?

O, and if it is H.A.A.R.P, and someone is generating quakes, I cannot imagine "they" would target Yellowstone unless they are suicidal fools.

More likely would be fallout from other events they triggered which they think they have under control. Afghanistan this morning for instance.

What if they are creating an unwanted ripple effect? I want them exposed, but not at all costs. However disaster horny I might be... Not at all costs...

Goodjob Redhatty, way to stay on top of things. This is what I was waiting for. To me the swarms near the fault line to the north dont both me at all. This is under the caldera which to me would be magma flow. Im glad they are admitting that its happening and that its odd. So none of us here are wasting our time =)

interesting.
RSOE just uissued a warning too!

About 5 posts up I answered that one for you.. after looking through the old quake listings... I never really found any swarms for that area.

Definitely found single and double quakes.. but no swarms.

My eldest daughter is a geologist and we discussed Yellowstone the other day. She had said that the plume is similar to Hawaii Volcanoes.

Also this below is very interesting. One reason the Yellowstone alert remains normal is because of lack of earthquakes.

Interestingly, the Yellowstone caldera has remained seismically quiet during the past three years of uplift. An earlier article on our website, Satellite Technologies Detect Uplift in the Yellowstone Caldera provides context on the techniques used to study these movements. The new activity, though more rapid than those previously measured at Yellowstone, is not unprecedented at large calderas around the globe. Given the absence of large earthquakes, earthquake swarms and anomalous behavior of Yellowstone's hydrothermal system (its geysers, mud pots and fumaroles), we find little indication that the volcano is moving towards an eruption. At this time, volcanic eruptions and hydrothermal explosions remain an unlikely possibility. Given the geologic history of the area, it is likely that the current period of uplift will cease, to be followed by another cycle of subsidence. When this might happen, though, is unknown.

IIRC, there are hundreds of remote monitors in Yellowstone - all over.

Sometimes one picks up a quake that another doesn't - like for example, one just happened and within seconds of it "ending" another begins - the 1st monitor is "resetting", so an alternate monitor records the second quake.

This is why humans have to go over the data from ALL the monitors in the specific area and the list gets manually updated.

That is a very simplistic example, but it gets the basic idea across
