Whats going on at yellowstone?

From the Mt.Washburn camera it looks like it's snowing heavily and that there's snow even on the screen in front of the camera. The Old Faithful cam appears to be down, but the live feed is working.

Averages 1 major hydrothermal explosion every 700 years and we're definately overdue for another by about 2300 years or 3000?
Maybe it won't be the end of the world if this puppy decides to bark!


P.S. I've got the webcams running fine, but I noticed lately you have to refresh the page often or you get the "we're sorry" message!(hi justmike) Before, I could leave it on the static old faithfull cam and it would run all night! Maybe because of increased traffic...

Hi Shirakawa,

the NPS webcam link appears to be unreliable right now -- it just went down again and got replaced by a "We're sorry" notice -- but you can get the same image via this link and it's updating fine every 25 seconds or so.

Regards,

I think we should be seeing some teleseisms from the 6.1 in Alaska soon.

Uh-oh... Big quakes in Alaska have been known to trigger quake activity in the Yellowstone region... (Details of the scientific reports are back in this thread somewhere.)

Time to keep an eye on the webicorders, for sure...

EDIT: That Alaska quake was at 18:09:50 UTC. Teleseisms are showing up on the Yellowstone webicorders just around 18:16 UTC, within the expected time frame for P-waves from Alaska. ie around 6 minutes or so:

Well that was different - I was looking at YS spike and suddenly felt the ground swaying... Bet that caused a stir for Homer, AK, but no wave action suspected (TG)..

reply to post by akjen
Yep, I'll bet it gave them quite a jolt in Homer. And as this quake is near the subduction zone there it could be a worry. Hopefully not, though.

Interesting that you felt some movement. Was it close to when the AK quake occurred or a fair while after? First P-waves only take a few minutes to reach most of the US, so if it was later it could be secondary effects.

Edited to fix coding glitch. Computer's fault, I swear...

Very close to when it happened but it took a few minutes for them to post it on the map. I'm about 180 air miles N of ground zero and felt slight rolling movement. I made a call to Dillingham and it was not felt but for some reason the television had lost it's signal??

I checked my bookmarks and found the article about an Alaska quake seeming to trigger quakes in Yellowstone. The quake on that occasion (back in Nov 2002) was a 7.9, which is far more powerful than today's 6.1. Even so, it's worth considering because of the recent swarms in Yellowstone; perhaps a quake of lesser magnitude than the one in 2002 might be enough to get another swarm going.

You can access the article here.

If anyone wants to read up on the Mag 7.9 Denali Fault quake, you can access the USGS report here.

Wow, now that is pretty close... Glad you had no serious effects. About the TV losing its signal: there could be several causes for that and no doubt our EE's on the thread would have more ideas than me, but I'm guessing it could've been something as simple as excessive vibrations at a repeater station tripping a sensor that temporarily cut the power. In an earthquake-prone area it would make sense to protect equipment from possible shorts and so forth if things start to shake too much.

Yea, you would figure in areas such as Cook Inlet that a lot would be done to protect things, people etc.. but HA HA when you have 30 + miles of heavy traffic roads built on glacier silt along the Inlet Basin ummm.. When downtown Anchorage was destroyed in 64 they just built more modern taller buildings right over the top.. When it happens again Cook Inlet will be a disaster zone with 10 times the population. People never learn from history. I was suprised that when a super-volcano is showing excelerated activity that the park would just allow people to be in the caldera. What is that about? Oh look - YS just had a 3.7 quake so lets go for a hike through the caldera!! The lack of respect just puts me in awe. Anyhow, there's my rant..

Study finds troubling pattern of Southern California quakes

This should be of interest for those of you who have been experiencing them lately

That's a good 2 mins of shaking. Reminds me of the Northridge earthquake that happened in 1994.

reply to post by manotick


Interesting, possible stress being relieved around the Carrizo Plain? There is nearly no activity in the mentioned zone either, it does make a sharp North-Northwestery turn in that area, so it could take alot of built up stress to get it moving again.

It is quite true that most posters to this website are subject to paranoia. To those posters, the following information must be disregarded, this post is NOT meant for you. To those who seek the truth, I offer the following information:

1. GOSA (Geyser Observation and Study Association) has replied that their data is behind. The eruption patterns and lengths must be examined for the time period of November 2008, through January 2009, to see if there has been any significant change in pattern.

2. Water outflow from Yellowstone Park needs to be characterized. See volcanoes.usgs.gov... on this. From the Yellowstone Lake outlet an estimated 70 to 180 million cubic feet excess over the 79 norm average has been fit using both a linear and quadratic least squares fit to the data. A significant change was noted starting December 13 2008 and continuing

3. GPS telemetry for all the available stations in Yellowstone Park needs to be examined, unfortunately the automatic graphics apparently has been disabled since December 30. Doubtless some will cry "conspiracy". However the LKWY station has shown about a permanet 7 mm uplift since Dec 24, 2008 if the raw data is believed factual.

4. Use of ASTER data is valuable, but only if buttressed with long term trend data and with experienced examination. Just thowing a photo up and drawing conclusions will nearly always lead to the worse possible conclusions being drawn.

For the most part, after the earthquake swarm underneath Yellowstone Lake bed from about Dec 26th 2008 through Jan 3rd 2009 there has not been too much change.

However any careful observer will note that Dr. Robert Smith and Dr Wu-Lung Chang and Dr. have studied the dilational effect of magmatic intrusion as evidenced by 2 recent earthquakes in Yellowstone Park. See Seismic Evidence for Dilatational Source Deformation of the Yellowstone Accelerated Uplift Episode Taira, T.; Smith, R. B.; Chang, W. American Geophysical Union, Fall Meeting 2008, abstract #V51D-2067. See also the abstract listing at adsabs.harvard.edu...

It is fairly safe to say that Dr Smith et al have been quite concerned about the recent swarm, and the recent paper shows their focus. However the tendency of human nature is to always imagine the very worst possible scenario and many postings to this forum manifest such.

I would suggest to the average person here that data sources do exist, if one is willing to work at it and do the work and useful results can be obtained. I would encourage people to go beyond speculation and examine the data to draw somewhat substantive conclusions, rather than to air opinion.

It is my best analysis at this point that Yellowstone Lake is at a 50% risk of having a significant hydrothermal explosion. Apparently the region is well overdue for such, having such an explosion on an average of 700 years apart and about 2300-3000 years overdue. It has been noted in Lisa Morgan's study that at least 8 hydrothermal explosions pocket the landscape. It is worthwhile to read the study at pubs.usgs.gov... the whole study is available in a single pdf file.

Finally to those who insinuate the character and moral nature of the USGS and other scientists examining Yellowstone, you need to shut up. I am not affliated with either government or any scientific organization so my rebuke is not from bias. Until you can do work on the same par as they, you need to keep your mouth shut.

I offer the above, in hopes that all will seek the truth, both about nature and about themselves.

Is "uh-oh" one word or two?

Ya know...I'm startin' to get a little edgy...seems like a lot of fairly large quakes all around the world...and they're not dying off...a few hours maybe a day lull and wham...too many in Cali for my liking...and that Alaska Eq...I'm seriously beginning to wonder if their might be something to the pole/core shift theorys...but one things fer sure, all that activity on the other side of the Pacific is upseting the balance in West Coast activity...

What ?USGS worry? nah . should we worrry yes we should

So what, there's 3 Plates converging here?

Your interpretation seems plauable...hopefully these radiating stress movements will help relieve coco's/pacific influence around the plain & Parkfield.
