Whats going on at yellowstone?

From that pagewww.telegraph.co.uk... Mr Smith, director of the Yellowstone Seismic Network said[This is an active volcanic and tectonic area, and these are the kinds of things we have to pay attention to," he said. "We might be seeing something PRECURSORY.

Don't like the sound of that.

Thank you,
We all know the outcome.
I did not want to go to the extreme and point that out again

yep great map - can any one confirm for sure that Mary Bay Crater is the Mary Lake in "YML" that had the harmonics. I'm thinking it is - but don't want us all to presume that there isn't some other actual Mary Lake in Yellowstone?

because then it is moving right over the danger spot isn't it.

Ok, I see now, thanks.
Still, the ones we saw in Yellowstone these days to me seem more of chaotical nature than harmonic. Maybe they were really just because of the bad weather.

Hi there,

your point about the weather would be quite reasonable were it not for that fact that there are historical seismograph records including volcanic, tectonic and harmonic wave forms that we can use for comparison, and which show the same features as those that have been recorded in Yellowstone during the past few days.

I suppose one way to explain this is to provide a copy of the seismogram chart for a station near Mt St Helens from May 18, 1980, which clearly shows these different waves forms and where they have been labelled by a seismologist. Please note that as this image will appear truncated, you need to right-click on it and select "View Image" to view all of it:



(Image from USGS and maybe be accessed here for those who prefer to go that way.)

The point is that where the harmonics are intense enough they do indeed look chaotic, because they "overlap" on their time-traces and without the color format used in modern helicorders, they would be as hard to discern as they are on the Mt St Helen's example from almost 30 years ago.

I hope this helps to clarify what we are concerned about and why, and also gives more members a chance to try and understand what they see on the various Yellowstone traces.

Regards,

Mike

Still checking but think maybe.
saw this articleposted this last Jan.
It is not so much the Tsunami info as the rest
so I thought I would pass it on:

sunami Linked to Yellowstone Crater
Scientist Believes Tsunami-Like Waves May Have Created Mary Bay Crater in Yellowstone

Tsunami-like waves created by an earthquake may have triggered the world's largest known hydrothermal explosion some 13,000 years ago, a federal scientist says.

The explosion created the Mary Bay crater that stretches more than one mile across along the north edge of Yellowstone Lake. Debris from the explosion has been found miles away.

Lisa Morgan of the U.S. Geological Survey told a gathering of scientists over the weekend at Mammoth Hot Springs that an earthquake may have displaced more than 77 million cubic feet of water in Yellowstone Lake, creating huge waves that essentially unsealed a capped geothermal system.

Though much has been made in recent years of a possible eruption of Yellowstone's "super volcano," geologists studying the park have long said that the likelihood is greater for a large hydrothermal explosion.

Morgan said that over the last 14,000 years there have been 20 hydrothermal explosions in Yellowstone that mostly left craters bigger than football fields. They resulted in well-known Yellowstone landmarks such as Mary Bay, Turbid Lake and Indian Pond, all near the north edge of Yellowstone Lake.

The explosions happen when hot water just below the surface flashes into steam and breaks through the surface.

Smaller explosions in Yellowstone happen about once every two years but rarely when people are around or in danger, according to a 2007 hazard assessment produced by USGS.


In 1989, an explosion at Porkchop geyser at Norris Geyser Basin sent rocks and debris flying more than 200 feet.

But geologists are still trying to better understand the larger explosions that happen about once every 700 years in Yellowstone and have left behind the biggest hydrothermal explosion craters in the world.

At Mary Bay, Morgan said she thinks there were at least two big waves before the explosion. Evidence of those waves has been found more than 3 miles north of the lake's edge, she said.

The explosion's column may have reached more than a mile in the air and spread debris across some 18 square miles, she said.

That really does show how worrying this is doesn't it? I am of the opinion we are going to see something erupt, but I don't think it'll be the "big one".

The comparison is quite startling, and I'm so glad they've developed a clearer method of depicting the movements.

My main focus right now is the apparent proximity of these events to a location that shows a cluster of hydrothermal craters. There seems to have been a lot of activity there in the past.

Has anyone found a site that shows the real time reading from any tiltmeters in the Yellowstone caldera that is what you start watching next.

they will start showing rapid ground movement as the magma chamber starts to swell. with gases and magma.
this is the only one i have found and the time period is to long to get a good idea what is happening.

Hi ANNED,

yes, that one you mentioned is interesting from a historical perspective but practically useless for our purposes, as you say. However, there is a site that shows what we're looking for. It the Yellowstone Continuous Auto-Processing GPS site, which updates fairly rapidly and give N/S, E/W and elevation change graphs for several stations within that area. You can access it here and it's well worth a look. The increase in dome height is quite evident.

Mike

Edit to add: it's still not an ideal data source due to the scales used but at least it's right up to date.

www.quake.utah.edu... that black one at 8:00 line looks of similar strength to the black one at 2:00 - it's a 3.3 on usgs

didn't someone say earlier that it first popped up as a 2. something - maybe they are downplaying and playing with the graphs - and thats why the lines were all screwed up with the colors a bit back. This thread is great - someone's always awake to be the big brother of big brother

Just found this warning on youtube uk.youtube.com... not sure if this official Here is the info that goes with it [Yellowstone volcano announcement. It won't be the Obama that changes the world. ] He seems a little unsure of the date, Monday or Tuesday.However he does say that we should be prepared.

Yikesss!

Right, so I'm developing my theory on this one...

Hydrothermal Explosion.

It seems these explosions happen every few years in Yellowstone, but there is evidence (specifically in the area where the current activity can be seen) that larger explosions have happened, the most recent seems to be about 3000 years ago.
Some of these larger events have left craters thousands of feet across.

While this is still a big event, the damage is less.

Check this link for a spokesperson of USGS aptly warning of just this scenario in January 2008.

Linky

Drudge Report is keeping up to date with this earthquake swarm.

No story. Just the map. 220 quakes and counting.

Hey - check out where YML is on this map - it's not Mary Bay Crater in the lake - it's where every once and a while there's been a tiny 1.0 square way off to the left of the lake.

Interesting,
until they mentioned the Bible.

It immediately lost all credibility when using religious text as a source.

Did you catch the news clip I posted just a few back?
It talks about MarysBay and what you are talking about

Here is a segment,

I tend to agree that there won't be a "big one", though rather than "thinking" it I'm just "hoping" it , because I'm not expert enough to know. Problem is, I'm not sure if even the experts really know exactly how big the eruption will be or even if an eruption is definitely imminent.

What we do know is that the series of quakes is tending in a pattern more-or-less NNW from the starting point and if this behaviour continues (and we have no way of knowing), then it gets worrisome because of all those smallish fault lines that are clustered around the mid-line of the big dome/bulge. And it's also worrisome because of the harmonic traces at YML, which became very strong from the latter half of DEc 29 into Dec 30 (UTC). They died down again but...just a minute...I'll check... Uh-huh. The activity there is picking up again. Now it's showing volcanic traces there, very clear ones -- and very similar to those I posted for Mt St Helen's a little while ago.

Hard to know what to make of this. I would like some expert input on what I think have been traces of long- and ultra-long-period events that show on some of the helicorders. They are extremely important as accoding to the scientist who discovered their significance, they only show up in large numbers just before a volcano blows and are a definitive precursor. But I lack the knowledge to be sure I'm reading the traces correctly on that score, so I'll repeat my plea from yesterday: if anyone can give a definitive answer on the possible traces for "long-period" or "ultra-long-period" events on those Yellowstone helicorders, please post and say so.

Edited to fix a very stupid typo!

Just found this video representation of the swarm of earthquakes at Yellowstone

Thanks for that, I should copy/pasta more often

Yep, I'm almost certain that this is what we're seeing.

Now the question remains, what kind of damage can we expect from this?

The evidence suggests an 18 mile radius of debris.

I think if we are about to see a Hydrothermal explosion the panic would cause more damage than the event itself, simply through people not understanding what is happening.
