Thanks for the response Roald. I shall have to research further.

I already had the quakefinder site address.

You know Putterman, the gradual uplift of Yellowstone’s caldera adds energy to the whole system. It adds to the whole deformation and expands the Great Basin to the west, and as the crust expands, it affects the rotation of the various tectonic plates underlying the region well beyond Yellowstone.

I also believe that there are local zones of molten magma in the upper crust. Near the northeast part of the caldera, because seismic velocities are lower to within about 2 miles of the surface; this for me indicate a more continuous magma body that extends from the northeastern part of the caldera to about 10 miles beyond it. Down below the crust and in the mantle at depths of 100 miles, lower than normal local seismic velocities may indicate thin rising columns of magma.

Earthquake data we both can study also suggest that soft or molten rock is close to the surface of Yellowstone. Minor earthquakes jiggle Yellowstone hundreds of times each year, but above the caldera the foci of these quakes are extremely shallow, less than three miles below the surface. These clues could suggest that the material underlying Yellowstone is still very hot and ductile, as would be expected if a magma chamber still exists.

Yup...and a few up in my little corner of the world.

Looking at THIS map, you'll notice our own little 'ring of fire' is starting to fill back in again.

New Yellowstone Research from the University of Utah

Recent research on the 2008-2009 Yellowstone Lake earthquake swarm and 2004-2010 extraordinary caldera deformation episode.

University of Utah researchers recently published two new articles in the journal Geophysical Research Letters that emphasize the active nature of the Yellowstone volcanic and hydrothermal system. The first article by Ph.D. candidate Jamie Farrell and colleagues summarizes research on the Yellowstone Lake swarm of late 2008 and early 2009. Besides a full summary of the characteristics of the swarm, they describe how the largest, deepest earthquake had an unusual volumetric (explosive) behavior, consistent with movement of fluid from depth and into the shallower hydrothermal system (less than 4 km or 3 miles deep).

Excellent catch!!!

That bit about the explosive EQ being indicative of magma moving up into the chamber is a bit scary though.

reply to post by PuterMan

quote:
Toba does exhibit some activity in the form of fumaroles but it is nothing by comparison to Yellowstone, It has had many fewer earthquakes and those that occur close to it do so because of the subduction zone close by and not because of the calder
-----------------------------------------------------------------------------------------------------------------------------------------------------< br />
Toba does has less activity comparing to yelly.......
but... is that an good sign ??
yellowstone was formed 640.000 years ago and the soil must have an much moore compact structure than toba wich is only 70.000 years old...
i can imagine that smaller EQ's are absorbed by an softer soil structure...
ore perhaps..its the opposite and there will be so much stress on the ground that it will heading for an really big EQ............

I followed the link on the USGS site to try and find full article. But I couldn't find it. Did you find the full study?

reply to post by Robin Marks


No Robin - I tried for a short period but was interupted by dreaded work that I had to attend to which took me the rest of my day in the office. Now on the dreaded dial up - which trying to follow such things lead to flying computers - If the new snow storm predicted to hit tonight isn't ice and I can get into work tomorow, I will try and get the full articles -- otherwise it will be a few days before I can search them out. I'm hoping there will be no charge for them - but, we know how that goes.

You know I was right about what's going on down there. The whole reason I migrated to this site was to warn people. My hypothesis relates to the exact scenario they've come to suspect. With the last swarm, the January 15th swarm, (bite your tongue) I stated that it was very much like the 1985 quakes. It would seem that the Lake Swarm was similiar as well. What does this mean exactly?

Don't worry I'm just warming up. Went icefishing today. -27C with a real stiff Northwest wind. -39C with the windchill. Me and my friend don't have an ice shack. I've only been here for five years and even the locals think we're hardcore. I thought I had caught the biggest fish but Anmarie caught the biggest. There goes my manhood.

I've been waiting for a real report that has used all the data to make a full interpetation.

I'll be back to rehash my conclusions I developed at the time of the events, and I'll post my experiment which demonstrates what happened when magma met water.

It's amazing really. The injection of magma into the chamber that started in 2004 came incredibly close to punching through the bottom of the lake.

I'll be back.

I'm too tired to write. Here's my simulation. The swarms are explosive events. The explosions are caused when magma comes into contact with water. It's a steam explosion. My experiment shows what happens when two different liquids, having much different temperatures interact in a dynamic fashion. It's a cascade because I was able to pressurize the chamber. My hypothesis is based on what the geologists have found when magma breaks through dykes and enters the geyer system. My hypothesis is what happens when this is repeated over time, causing structural faults and large dykes. This undermined the crust. The lid on Yellowstone's cauldron is not like the lid on a pot on your stove. It's not a solid piece. If these explosions continue over time, large sections of the crust become unstable and break from the rest of the crust. These segments turn to magma. The gases are compressed and can start to migrate upward finding pockets, or dissolving into the aquifer. Steam explosions open up more pockets allow more water to enter the aquifer. When the system reaches a point that there is a multitudes of fracture areas, and a maze of wandering dykes and a larger channels for water, it starts to accelerate. Once the is a major fracture allowing water and magma to have large volumes interacting, the cascade begins. The more water entering and finding the magma, the more steam and more explosions. The more explosions, the more the water and magma can interact, and the more they destablize the crust and open up pockets. And so on and so on in a cascade..

BBRRRRR!!!! I figured if you could withstand that, I could withstand searching here on this dreaded dial up. Article 1 Seismic evidence for dilatational source deformations accompanying the 2004–2008 Yellowstone accelerated uplift episode

Don't think this is the one - i have multipal pages to go through - whoopsie - dates are wrong although put out recently

reply to post by Anmarie96


Don't hurt yourself looking. It's as we expected, you gots to pay.

Clear skies tonight. Means all the heat is rushing toward the stars. It's going to dip to -32C with a wind chill, that's -44ish. I moved here because I wanted the cold. I got out of the fire on purpose. Never regretted it for a moment. I'm going out later to watch the stars. Earlier tonight I saw a metorite. Saw cross the sky leaving a smoke trail. It seemed to be corkscrewing and it dimmed once and then came back brighter with an red/orange colour. It burned out a brief moment later. It's not the biggest or closess I've seen. Once I saw one up close. It was green, with bits of red/orange flying off of it as it broke apart. That one was photographed and many people saw it.

I know it seems silly. But I think if I go outside and look I'll see another. Saw the space station the other night. Looking up is cool

One last marvel. The cold and the way it contracts. It's almost like listen to earthquakes when you hear some piece of metal suddenly start contracting. The sun had warmed it up, but as soon as the direct rays stop, it quickly cools and makes a racket as it snaps and pops.

On the ice it's like you feel a bunch of earthquakes. As trucks drive by you, there is a wave they make when they move. It preceeds the vehicle and you can feel trucks before you hear or see them. And when the pass you can hear the ice crack and buckle under you. It's a surreal experience. That, and the fact your out driving around on one of the biggest lakes in the world. With tens of thousands of islands. Old mountain ranges flooded by glaciation. That's enough.

We all talked about this in debth about 200 pages ago. Your u-tube video is an excellant example. You know Robin, these reports are items that we have all chatted on at length about here on this thread - as are alot of reports that They put out. -- You say no one is listening to you or us, - I think you are very wrong in that. And - If you look very closely at news items along with research - you will see that They and the news - report = it has been theorized or discussed etc. remember = read in between the lines

643 pages and 389 flags...just wondering why this thread isnt on the "Top Topics+" list...

reply to post by Prokopio


I think because it is an ongoing thread that waxes and wanes as the Caldera does her thing. When she is busy, we are busy and when she rests as she is doing now we just sharpen our skills relating to volcanism and quakes on other threads.

reply to post by Anmarie96


I understand what you mean. There's been a few times that I felt someone was paying attention. Peter from YVO says he lurks. You must be refering to the fact that people took my fracking idea and ran with it. I am still investigating the quakes and was scanning the headlines when I read some blogs. I then realized that they were forwarding my words. I kinda freaked me out. I then backtracked and found a thread you made. Thank you. There were at least two blogs that I know directly pointed to my hypothesis. I then realized when I heard news reports that were cruising the blogs and asking the Arkansas Wildlife people about some of the whackiest... I really didn't realize that I was the source of the gas theory. It's completely logical. I was the first because I was immediately on top of the story and start making the case immediately concerning my hypothesis.

Of course the resident would tell you that the earthquakes were caused by the fracking. But I don't think they understood exactly what happened to the birds and fish. That took detective work. Witness statements.

Fish were killed by a seep. The birds were killed by gas rupture which created a loud bang, "poof", followed by a gas release, the "whooshing noise". The sent the birds into a frenzy. That's the case solved and simplied.

So I'm impressed that my "whacky" idea made it off these pages and made it's way into the public arena. I hope I made people think about what's really happening in Arkansas. The drill pads are huge and there right on top of a major swarm.

Yellowstone. I pray the are fracking at a safe distance from Yellowstone. All I can say is that I definately do not have blind faith in our experts. Geologists and engineers, and execs doomed the Gulf. All experts, well paid and the government has entrusted them with our most precious resource. It's not oil. It's water.

They're fracking with our water.
We are water.
So they're fracking us.

Just stopping by with a hot cup of Coco and to say thanks for all you guys do to keep us warned and safe. Love to spy on your conversations and discussions but tonight figured I would bring this treat.

Since the caldera are relatively calm when it comes to quakes might just mean that we do have an uplift somewhere. Let's look for some data..

We know that there have been a caldera‐wide change to subsidence along with coincident changes in horizontal motions (e.g., from SE to NW at WLWY) during the first six months of 2010. And maybe as the caldera source continues inflating, the accumulated strain energy in the deformed crust could promote earthquakes with mechanisms such as hydrofracturing, migration of magmatic fluids, and brittle fracturing of rocks? If so, then maybe these events can depressurize the magmatic systems or release the accumulated strain energy, slowing the uplift or even influencing a change in motion to subsidence.

In January 2010 the Yellowstone caldera experienced a large earthquake swarm at its northwestern boundary, close to the location of the 1985 swarm. In the following five months the caldera experienced the first overall subsidence since the inception of its uplift in 2004. This scenario is similar to that in 1985 where a reverse of caldera uplift to subsidence was temporally correlated with the largest observed Yellowstone earthquake swarm.

I think that this observation provides evidence for the correlation between transient ground deformation and changes in seismic activity of the Yellowstone region.

I still believe that magmatic intrusions at 7–10 km beneath the caldera have been responsible for the uplift since mid‐2004, but that a decreased rate of magmatic replenishment from beneath the northeast caldera and an increase of seismic moment release could be a plausible mechanisms for the continuing but declining caldera uplift.

GPS data, to June 2010, reveal the beginning of a caldera‐wide subsidence following the January 2010 Yellowstone earthquake swarm.

Taking the Temperature of the Norris Geyser Basin

The Norris Geyser Basin has long been known as highly dynamic, and recent evidence implies that the area may be highly responsive to earthquakes and ground movements associated with inflation and deflation of the Yellowstone Caldera. In an effort to better document changes in water flow and heat discharge from different parts of the basin, YVO recently installed a series of radio-equipped temperature sensors. The equipment was purchased and installed with funds made available through the American Reinvestment and Recovery Act (ARRA).
