Whats going on at yellowstone?

A new series of what are described as a "modest swarm of earthquakes" began Friday in Yellowstone National Park, about 10 miles northeast of the north end of Yellowstone Lake, where a swarm of approximately 900 quakes had occurred between Dec. 26 and Thursday. The current swarm is located on the northeast corner of the Yellowstone Caldera, according to the Yellowstone Volcano Observatory. The new swarm, so far, is considerably smaller than the first series. The migration of the quakes continues in a north-northeast direction. The largest of the new swarm of quakes was a magnitude 3.3 recorded at 11:17 a.m. Friday. The observatory said its staff and others are analyzing the data from the latest swarm and earlier Yellowstone Lake swarm. They are checking for any changes to the thermal areas located near the epicenters. Of the earlier swarm, 500 have been reviewed by seismologists, said the observatory; 111 of those earthquakes had a magnitude of greater than 2.0, and 18 earthquakes were greater than 3.0. The swarm of tremors is the largest series of back-to-back quakes to hit the area in years, according to scientists. No damage has been reported within Yellowstone National Park from the quakes, although the strongest have been felt by park employees and visitors.

According to the observatory, Yellowstone seismicity increased significantly in December because of what it described as an "energetic earthquake swarm" that began Dec. 26. The last major earthquake swarm was in 1985 and lasted three months. The Yellowstone Plateau, which comprises Yellowstone National Park, is one of the largest super-volcanoes in the world. It has gone through three volcanic cycles spanning two million years that included some of the world's largest-know eruptions. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world. The most devastating earthquake in recent history in the Yellowstone region occurred on Aug. 17, 1959, when a magnitude 7.1 earthquake hit. It was centered near Hebgen Lake, Mont., killed 28 people and caused more than $11 million in damage. Afterward, Yellowstone geysers changed eruption times, and new ones began to spout. On June 30, 1975, a magnitude 6.4 tremor hit the park. The observatory was created as a partnership of the U.S. Geological Survey, Yellowstone National Park and the University of Utah. It monitors long-term volcanic and earthquake activity in the Yellowstone National Park region.

then i gotta be at the wrong site.

just take me out back and shoot me........ ahhhhhhhhh
thanks for the good working link.

Wow, this is quiet.
Like watching a clock tick

Could be nothing more than breaking or fracturing rock .
ummm.
like watching a thriller,little ticks here and there, and then all of a sudden something is going to pop out at us.

Morning to you far out West,

I posted earlier but found no replies to my questions.
And as time passes I come up with new ones as well.
Here goes:
- How would anyone be able to distinguish harmonic tremor on a kind of seismogram that we see on most sites?
If the info is right the amplitude of the tremors iis smaller than we can make out on our screens. Example taken from www.isthisthingon.org...
makes it imho clear.
- How come nobody over here is interested in the fact that some organization maybe USGS (haven' t looked into it any further yet) requested an ASTER survey for coming January 22 and 25 mentioning it was urgent! See asterweb.jpl.nasa.gov... , as was pointed out to us by our anonymous Spanish friend a couple of threads ago?
- Would I be correct in assuming that low amplitude activity on some stations is due to wind? It does look like it as when, on plateaus exposed to wind, the effects are more distinctive than when stations are located in creeks or such.
- In these troubled economic times, wouldn' t it be wiser, from the point of view of the scientists, to insure they keep on getting the necessary government funds to safeguard their projects as well as their livelyhood? If that is the case then there would be no motive for them to downplay the current events.

I keep on being intrigued by this thread. Don' t ask me how I found it as honestly I wouldn' t know but it seems some more people from over in Europe found it.

Roby

PS (I love PSes as I am in the habit of forgetting things) Yellowstone gets some attention in Europe as well on scientific sites but no additional interesting info is to be found yet.

LOL..
Seems some people need to realize tht 1000 years in human time is but a blink of the eye in geological time.
One thing I have learned from this event and thread is just how interconnected everything is, and how everything has purpose.
What haappens in Alaska, has a trickle down effect on wht happens at Yellowstone.
Everything happens for a reason.
Very humbling and amusing to witness.
If we were to extrapolate that into our own lives, you can begin to see just how your actions effect pther actions.
The events of the past few weeks may be precursers to something that happens in a week...or a month...or 1,000 years, but it all happens for a reason.
It is exciting to witness.
If we are lucky, it will happen during our brief stay here.
Just imagine bearing witness to something that happens every 600,000 years!

I just had a funny thought.
Anybody remember the Tv ad -gas, bloating , indigestion ... alka-setzer I think
Can you imagine the earth pictured out in space doing the same movements.
Tee hee
going to check one of the other graphs here...

reply to post by robystar

I got a reply from a Geophysicist on these things . Would you like to see how he answered some of these things?
How to discern one thing from another and how they filter?

Mushussu,

What do you think I' d reply?
Of course I am interested to know!
Let' s hear it.

I don't think a 2.0 magnitude earthquake would be able to reach Yellowstone from Alaska... it must have been something else.

reply to post by Moshpet


Looking back through the logs that would match-up

Huh I must of missed that NASA Flyby note a few back...now that's intriguing...wonder if it's GPS or Thermal or WHAT?

reply to post by robystar


wooo this site has ys in the red zone for urgent attention ... and its nasa... simply amazeing work ...


well done.

reply to post by robystar

His responce to me was CC'd to some Higher ups as well and they said well done to him for these answers:

""Your message was eventually forwarded to me for a response. I am a geophysicist at the USGS Albuquerque Seismological Laboratory (ASL). We install and operate seismograph stations both in the U. S. (the Advanced National Seismic System - see earthquake.usgs.gov... ) and globally (the Global Seismograph Network - see earthquake.usgs.gov... ).

Modern broad band digital seismograph systems produce data that covers a broad range of frequencies from tidal periods (12 hours) to tens of Hertz. As you rightly point out, such recordings include not only signals of interest (from earthquakes, volcanoes, and underground explosions, for example) but also from noise sources such as trucks, cars, airplanes, wind, and bears scratching their backs on trees. Another noise source that's constantly present is something called "6-second microseisms," which come from ocean waves generated by storms and wind at sea. This type of background noise is higher on islands and near coastal areas, but is also present in the middle of continents.

Yes, we do filter out background noise so we can see signals of interest. One very nice example of what filtering does for us can be seen at the following web site:

aslwww.cr.usgs.gov/Seismic_Data/liss_data.html

At this site you will see a short list of links including three links to 24-hour seismograms from COR (the GSN station at Corvallis, Oregon). The unfiltered broad band data is seen at:

See the preceding twenty-four hours of unfiltered short-period data from COR (Corvalis, Oregon).


Unless there is a large earthquake somewhere in the world or nearby, this unfiltered seismogram will show mainly 6-second microseismic background noise. Now go back and click on:

See the preceding twenty-four hours of short-period data from COR (Corvalis, Oregon).

This is the same 24 hours of data, but filtered to show only 1 Hz and higher frequency ground motions. On this seismogram you will see high frequency signals from small local or regional earthquakes as well as high frequency noise from occasional traffic passing on the road nearby. Now go back again and click on:

See the preceding twenty-four hours of low-pass long-period data from COR (Corvalis, Oregon).

Again, this is the same 24 hours of data, but filtered to show only 0.02 Hz and lower frequency ground motions. On this seismogram you will see mostly only low frequency surface waves from distant earthquakes (teleseisms). Note that both the high frequency noise from traffic and the 6-second ocean wave noise has been filtered out on this seismogram.

So, as you can see, the broad band data can be filtered into various bands of interest to help filter out various types of noise or to emphasize frequency bands of interest. Now, if you're interested, you can go back and click on:

See the preceding twenty-four hours of short-period data from ANMO (Albuquerque, New Mexico).

This is the 1 Hz and higher filtered version of broad band data recorded from a seismometer in a 100-foot deep borehole here at ASL. If you look at this seismogram on a work day, you will notice that it's noisier than on a weekend day. This is because it's recording the noise caused by people's cars as they come and go here at the office. It also gets noisier when the wind is blowing. (The wind pushes on the buildings and the juniper bushes, producing high frequency noise that gets propagated down into the ground and picked up by the seismometer.) Also, the heaters and AC systems in the buildings generate a little bit of high frequency noise. (We run the HVAC systems much less on nights and weekends.)

Finally, you can look at long period seismograms (filtered to pass frequencies lower than 0.02 Hz) from the GSN stations by clicking on Thumbnails of the 24-hour heliplots.""

Another wrote this:
''We don’t have many problems with wildlife, the solar panels are too high up and the sensors are below ground with no surface exposure. We do have the occasional problem with VSAT or telemetry radio cables being cut or compromised by animals. Woodpeckers have poked holes in VSAT cables. Rats and mice have chewed through cables or managed to get inside a sensor vault and make their home under a sensor which created massive noise spikes. Cows and bears have used the equipment poles to scratch on and have broken cables. All of these problems are local to a specific sensor and are not deemed seismic events just by the fact that there are no other sensors that registered the same event, and therefore are dismissed as noise or an anomaly specific to that site. We try to inhibit wildlife from coming in close proximity to our stations with fences, underground sealed vaults, closed equipment shelters and buried cable runs, but the situation does arise every so often. We usually don’t know the cause of station excessive noise or an outage until we make a site visit for a repair action, that’s when we find animal intrusion or damage from wildlife and have to try to eliminate the source of the outage before leaving the station, by installing fences, putting steel wool in cable conduit (to keep rodents out), rerouting cable runs and covering cables with conduit or earth."



I see some of the sites did not go through.
Working on it

Hello all!

Well, after reading this thread since about Dec. 29th, I thought I might join in on the fun!

One thing I've noticed... Remember right after the initial swarm when we were seeing that funny signature on LKWY? The one that someone said might be a long period signature or something like that, because it kept coming back and increasing in intesity? Well, looking at LKWY today, I think that we might be seeing something like that again. It's showing little pulses that fall into a regular pattern, starting at about 3 MST. They just seem a little too regular and long lasting to be trucks or people going by. Anyone have any thoughts?

reply to post by YS Watcher


I see what your talking about...now LKWY is set at 500Mv instead of 100Mv like last swarm? (Wrong ...it was at 500Mv back then) Wonder if they're trying minimize/filter whatever that is?
