Subject: Expert could be lying...

I have been looking into this big time, and it seems many people who research volcanoes and Yellowstone have evidence that recent records of Harmonic tremors have been removed from USGS site, but they are still on other sites. The swarms have slowed down some, but they are still happening. And there is no mention of the harmonic tremors at all. Then they remove them from the sites soon after being posted???

Ok, current facts are these;

1 - For the last twenty years, the magma chamber has been filling up.

2 - Earthquakes worldwide are right off the scale!

3 - There is a prominent bulge under the lake, that has been studied extensively recently.

4 - The recent swarms of earthquakes are directly under the lake.

5 - The main thing to watch for around the lake is Harmonic tremors, because that signifies that the magma is moving. But they haven't admitted that there have been records of these since the 26th of December. Records that have been removed from USGS site.

6 - So.. if they know there are harmonic tremors, why haven't they told us?

7 - Watch the movie Supervolcano, and you will see glaringly obvious similarities to what is going on right now. Especially the parts about them having the evidence, yet not alerting the public and evacuating. Is it because they don't want the panic seen in the movie? That would be my guess.

I've been told that the GF are watching Yellowstone closely, and the second it starts to blow, they push the button to start full-scale evacuation. The only safe place to be during a Yellowstone major eruption is on the starships. And they also said this could get bad.

Naturally, the explosion would start the pole shift.

Dear T:
   
    The Yellowstone volcano caldera covers the entire area within the Yellowstone National Park in Wyoming, USA.  Since recorded history this area has shown many signs of instability.  The geologic record shows that this supervolcano has blown many times at intervals of six hundred thousand years, with the last eruption of, guess what, six hundred thousand years ago!
 
    Yesterday I received word from a person living in Wyoming, who has been following the "activity" of Yellowstone, who said that even though it is mid-winter with much snow and not melting in the area, the flow of water from Yellowstone Lake into the Yellowstone River has greatly increased, but no one is talking about it.  This would indicate that the magma dome under Yellowstone Lake is rising and pushing the water from the lake.
 
    Here in Rapid City, South Dakota, we are about three hundred and fifty miles from Yellowstone.  We have both local and national T.V. advertising (CNN) encouraging tourists to come to Yellowstone National Park for great winter sports and scenic beauty.  The Park Service does not tell you about the dead fish in Yellowstone Lake that have died due to sulfur gas and rising water temperatures.
 
    They do not tell you about the bear, elk, moose, deer and wolves that have moved to the perimeter of the park or of the dead animals that have died for unknown reasons.  The Park Rangers do not tell you of the areas of the park they have closed to the public due to the hot walkways, where the shoe soles melt to the walkway.  It is all about money and propaganda and fool the public.
 
    Geophysicist Soltec and his crew aboard the Phoenix are in charge of monitoring earth changes.  They are keeping a very close watch of the Yellowstone Supervolcano, and will know well in advance when "she blows".  With that and a pole shift, we are out of here!  Just know that all is well, and a planetary evacuation is imminent.
 
                            In Love and Light,
                            Patrick H. Bellringer

Scientists Eye Unusual Swarm Of Yellowstone Quakes
December 30th, 2008 By MEAD GRUVER , Associated Press Writer in Space & Earth science / Earth Sciences
 
(AP) -- Yellowstone National Park was jostled by a host of small earthquakes for a third straight day Monday, and scientists watched closely to see whether the more than 250 tremors were a sign of something bigger to come. Swarms of small earthquakes happen frequently in Yellowstone, but it's very unusual for so many earthquakes to happen over several days, said Robert Smith, a professor of geophysics at the University of Utah.
 

"They're certainly not normal," Smith said. "We haven't had earthquakes in this energy or extent in many years."

Smith directs the Yellowstone Seismic Network, which operates seismic stations around the park. He said the quakes have ranged in strength from barely detectable to one of magnitude 3.8 that happened Saturday. A magnitude 4 quake is capable of producing moderate damage.

"This is an active volcanic and tectonic area, and these are the kinds of things we have to pay attention to," Smith said. "We might be seeing something precursory.

"Could it develop into a bigger fault or something related to hydrothermal activity? We don't know. That's what we're there to do, to monitor it for public safety."

The strongest of dozens of tremors Monday was a magnitude 3.3 quake shortly after noon. All the quakes were centered beneath the northwest end of Yellowstone Lake.

A park ranger based at the north end of the lake reported feeling nine quakes over a 24-hour period over the weekend, according to park spokeswoman Stacy Vallie. No damage was reported.

"There doesn't seem to be anything to be alarmed about," Vallie said.

Smith said it's difficult to say what might be causing the tremors. He pointed out that Yellowstone is the caldera of a volcano that last erupted 70,000 years ago.

He said Yellowstone remains very geologically active - and its famous geysers and hot springs are a reminder that a pool of magma still exists five to 10 miles underground.

"That's just the surface manifestation of the enormous amount of heat that's being released through the system," he said.

Yellowstone has had significant earthquakes as well as minor ones in recent decades. In 1959, a magnitude 7.5 quake near Hebgen Lake just west of the park triggered a landslide that killed 28 people.

A comment on the site, a bit worrying.
 
Quote:
People out here in Yellowstone-land are reporting weird pet and human behavior - moodiness, restlessness, etc. Also some strange wildlife encounters, such as a fox that will not quit barking, flying squirrels very active in daylight and a bull elk running down the highway (should have migrated down the mountain weeks ago, but it came back for some reason), grizzly bears that have not hibernated yet. Waiting to hear from friends in the park about wolves, bison, elk, wintering birds, etc. Adds another dimension to small talk - usually it's just about how much snow we have, how many plows are broken down, etc.

More questions from Rufus the layman: Numerous postings on other sites claim that the outflow from Lake Yellowstone has increased dramatically the last few days..Is that true???.Might that not indicate that the bulge under the lake is growing and displacing more water???....Other posters allege that rivers in various locations around YNP are showing higher temps then normal??.....I notice that activity has really quieted at Yellowstone today..I was a teenager living in Portland when Mt St Helens blew in 1980, ( I could actually see it from my porch in Portland's SW hills)..As I recall the activity; steam & ash columns and the formation of the bulge, started in late March and continued, more or less continously until May 14, when, as I recall, activity ceased...Then four days later the Mountain blew...Is that a normal pattern for explosive eruptions??.

Thanks for your answers to my previous questions....

Most of the post was cut off... what I said was that they can only claim lack of concurrent eruption indicators because they're not looking for them. There's no camera on the Lake to see gas emmisions. There's no temperature sensors to see increases. They won't do a bathymetric survey to compare to the 2003 survey to detect Lake bed deformations. Their seismographs are too dispersed to resolve magma chamber deformations

Posted by: KYAGB | January 6, 2009 3:54 PM

I have found the spot of the next Super-eruption. It is the Huckleberry Ridge Tuff Fault.The first caldera. It runs through the middle of the lake, precisely where the swarm began. On top of the fault is the West Thumb lava flow. This cap has fractured. The first caldera rim also intersects with the Sour Creek Dome. The next eruption will begin just north of the Lake along the Huckleberry Ridge Tuff and Sour Creek fissures.The Elephant Back fissures also intersect the original caldera. The fault under the lake will allow water to enter the subterranean aquafiers. This will lead to the collapse of the geyer systems which will trap steam on top of the chamber. The system will be in a cascade once the process begins. Link to my small scale experiment to see what will happen. It will happen soon. In fact it may have already started.

Dear Pyre,

Sorry for the confusion. To clearify, I have found the precise location of where the next Super-eruption will begin. The next Super-eruption will begin along the Huckleberry Ridge Tuff where it intersects with the Sour Creek Dome.

Experts are watching, and probably sipping their coffee, too.

 
Seismologists have recorded 900 quakes
 

By BRETT FRENCH

Of The Gazette Staff

According to the latest information from the Yellowstone Volcano Observatory, about 900 earthquakes occurred between Dec. 26 and Jan. 8 in the Yellowstone Lake area.
Five hundred of the quakes have been reviewed by seismologists. There were 111 earthquakes with magnitudes greater than 2.0 and 18 earthquakes greater than 3.0. About 400 smaller earthquakes have yet to be reviewed.
The largest earthquake during the swarm, on Dec. 28, was of magnitude 3.9. One of the measurements that seismologists use to talk about earthquakes and swarms is the cumulative seismic moment, which is a measure of the earthquake energy. The cumulative moment (the energy from all the analyzed earthquakes in the swarm) for the Yellowstone Lake Swarm is equal to the energy of a single magnitude 4.5 earthquake.
Earthquakes with magnitudes less than 3.4 are generally not felt by people unless the quakes are very shallow, and then only close to the epicenter. For perspective, earthquakes of magnitude 3.4 to 4.5 are often felt and there were multiple reports of felt earthquakes during this swarm. A magnitude 5 or greater is generally required to cause damage to buildings or other structures.
It doesn't have to be a large quake, it only needs to destabalize the magma chamber!

Seismic activity at Yellowstone Lake in Yellowstone National Park increased in late December 2008. As of January 8, 2009, the seismic activity has markedly decreased (Listen to a podcast with YVO's Scientist-in-Charge about the recent swarm). It is possible that the swarm has ended, although a return of activity may occur as previous Yellowstone swarms of this size have lasted for tens of days to many weeks. Swarms are common at Yellowstone. The last notable swarm occurred in 2004, please see our 2004 article, Yellowstone Earthquake Swarms for more background on earthquakes and swarms at Yellowstone.

Seismologists continue to review the earthquakes

About 900 earthquakes occurred between Dec. 26, 2008 and Jan. 8, 2009 in the Yellowstone Lake area. Five hundred of the earthquakes (including all greater than magnitude 2.0) have been reviewed by seismologists. There were 111 earthquakes with magnitudes greater than 2.0 (> M2.0)and 18 earthquakes > M3.0. About 400 smaller earthquakes have yet to be reviewed. [A new Frequently Asked Question about earthquake analysis will be posted here soon]. The largest earthquake during the swarm was a magnitude 3.9 on Sunday, December 28, 2008. One of the analyses seismologists use to talk about earthquakes and swarms is the cumulative seismic moment, which is a measure of the earthquake energy. The cumulative moment (the energy from all the analyzed earthquakes in the swarm) for the Yellowstone Lake Swarm is equal to the energy of a single magnitude 4.5 earthquake (see Image 3).

Depths for shallow earthquake hypocenters (the point within the earth where an earthquake rupture starts) are difficult to determine accurately unless the seismic stations are spaced much more closely than those in the Yellowstone Seismic Network. The best located earthquakes have hypocenters (depths) of 3 to 10 km (1.8 to 6.0 miles). From Dec. 26 through Jan 2, the hypocenters appear to have migrated northwards, starting southeast of near Stevenson Island, with many of the latest events occurring near Fishing Bridge.

Swarms are normal at Yellowstone

The recent swarm is well above typical activity at Yellowstone. Nevertheless it is not unprecedented during the last 40 years of monitoring. Earthquake swarms within the Yellowstone caldera are typical, with magnitudes occasionally ranging above 4.0. The 1985 swarm on the northwest rim of the caldera lasted for three months, with earthquakes up to M4.9 and over 3000 total events recorded.

The magnitudes of earthquakes in this swarm range from zero to 3.9. Earthquakes with magnitudes less than 3.4 are generally not felt by people unless they are very shallow and you are standing very close to the epicenter (point on the earth's surface above the hypocenter). For perspective, earthquakes of magnitude 3.4 to 4.5 are often felt and there were multiple reports of felt earthquakes during this swarm. A magnitude 5 or greater is generally required to produce damage to buildings or other structures.

number of earthquakes; the steep slopes correspond to increase in earthquake number. The

red line in the figure on the right gives the cumulative moment, or energy; its sharp

increase in the first few days is due to a greater number of large earthquakes with their

greater energy release. The total cumulative moment is equivalent in energy to about one

M 4.5 earthquake. Click on the image for a full-size version.

New equipment allowed us to monitor the swarm

Improved volcano and seismic monitoring at Yellowstone gives us a greater ability to locate earthquakes, understand their source process and identify anomalous sources of seismic activity. New equipment including precise measurements of ground motion by GPS receivers and borehole strainmeters provided by the National Science Foundation's EarthScope and Continental Dynamics Program have been used extensively during the last week of intense earthquake activity. Ground motions accompanying the swarm, from the GPS instruments will take two or more weeks to fully process. It is worth noting that in 2004 the Yellowstone caldera began a period of accelerated uplift measured by GPS instruments that was as large as 7 cm/yr (2.7 inches/yr), three times as fast as recorded in the recorded history but has now reduced to about a maximum rate of 4 cm/yr. Scientists have modeled this deformation as due to magmatic recharge of the Yellowstone magma chamber at a depth of ~10 km (6 miles). The area of the swarm is on the eastern side of the uplift area. For more information on the uplift, please see our article Recent ups and downs of the Yellowstone Caldera.

There are several causes for earthquakes

Earthquakes at Yellowstone are caused by a combination of geological factors including: 1) regional stress associated with normal faults (those where the valleys go down relative to the mountains) such as the nearby Teton and Hebgen Lake faults, 2) magmatic movements at depth (>7 kms or 4 miles), and 3) hydrothermal fluid activity caused as the groundwater system is heated to boiling by magmatic heat.

At this time, no one has noted any anomalous changes in surface discharges (hot springs, gas output, etc.).

We continue to monitor Yellowstone Volcano

YVO staff from the USGS, University of Utah and Yellowstone National Park continue to carefully review all data streams that are recorded in real-time. At this time, there is no reason to believe that magma has risen to a shallow level within the crust or that a volcanic eruption is likely. The USGS Volcano Alert Level and Aviation Color Code for Yellowstone remain at Normal and Green.

Yellowstone National Park is evaluating infrastructure near the north end of Yellowstone Lake to assess if any damage has occurred to facilities.

Winter visitor activities and staff operations have not been impacted and continue as normal.

The Yellowstone Volcano Observatory (YVO) is a partnership of the U.S. Geological Survey (USGS), Yellowstone National Park, and University of Utah to strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

Ominous Increase in Water Flow from Frozen Yellowstone Lake, 6th Day of Tremors Below Lake
 
 
The current situation at the Yellowstone Super Volcano is playing out along almost the same general plot line as the 2005 made for TV action thriller movie Supervolcano about an eruption at Yellowstone. The problem is this is real. In the movie the USGS and Federal Government could not come to grips with the shear level or potential of the disaster. (Katrina x10,000) In the end they buried their collective heads in the sand until it was too late to make any constructive preparations.

Today just like in the movie we get snippets of information from the team monitoring the situation at Yellowstone saying this is a different from any events they have seen at Yellowstone before and they are not sure what is causing it.

The facts:

The tremor swarm is still going on for the 6^th^ day. It will sometimes calm for a few hours but as soon as you think it is over the seismographs yet again start beating out a tempo of small tremors. And when coupled with other disturbing signs such as an increase in water flow from the frozen Yellowstone Lake directly above the tremors we know that the ground has become restless. Something is undeniably happening at Yellowstone.

Do a web search on Yellowstone and you will see a pattern of concern over the last several years at new and different events have happened and sometimes baffled scientists. All of the events when taken as a whole could point to something happening at Yellowstone.

The fact is now something is happening; earthquake swarms of this size and duration at known volcanoes often precede events at those volcanoes. .

A great quote from the movie Supervolcano was made by Michael Riley playing the role of Richard 'Rick' Lieberman

"When Mt. Vesuvius erupted, the people of Pompeii stayed in their homes, how do we know that Ken?"

Alaska quake altered Yellowstone hydrothermal system
 
June 9, 2004
A powerful earthquake that rocked Alaska in 2002 not only triggered small earthquakes almost 2,000 miles away at Wyoming's Yellowstone National Park, but also changed the timing and behavior of some of Yellowstone's geysers and hot springs, according to a new study published in the June issue of Geology. 
 
"We did not expect to see these prolonged changes in the hydrothermal system," said University of Utah seismologist and study co-author Robert B. Smith. 
 
While other large quakes have altered the activity of nearby geysers and hot springs, the Denali fault earthquake of Nov. 3, 2002 in Alaska is the first known to have changed the behavior of hydrothermal features far away. The magnitude-7.9 quake was one of the strongest of its type in North America in the past 150 years. 
 
Within 18 hours of the Denali earthquake, scientists at University of Utah seismograph stations reported the major jolt had triggered more than 200 small quakes in Yellowstone. 
 
Smith said the triggered quakes at Yellowstone numbered more than 1,000 within a week of the Denali quake — if the count includes tiny temblors that were not "located" (i.e., their epicenters and depths were not determined). The quakes ranged in magnitude from minus 0.5 to just under 3.0, according to Smith. (Tiny quakes have negative magnitudes because today's seismic equipment can detect quakes smaller than was possible when the logarithmic magnitude scales were devised.) 
 
Most of the triggered quakes were centered near geysers and hot springs. 
 
Strong earthquakes as seismic and geothermal triggers
 
Scientists once believed that an earthquake at one location could not trigger earthquakes at distant sites. That belief was shattered in 1992 when the magnitude-7.3 Landers earthquake in California's Mojave Desert triggered a swarm of quakes more than 800 miles away at Yellowstone, as well as other temblors near Mammoth Lakes, Calif. and Yucca Mountain, Nev. 
 
The magnitude-7.5 Hebgen Lake, Mont. quake northwest of Yellowstone — a 1959 event that killed 28 people — triggered changes in Yellowstone's geysers and hot springs, something not unexpected for a strong quake nearby. 
 
The Denali fault ruptured in such a direction — from northwest to southeast — that the brunt of its energy and its powerful surface waves were aimed southeast toward Yellowstone, Smith pointed out. As a result, the stresses rippling through the ground at Yellowstone were 200 to 300 times greater than if the Denali quake's waves were aimed elsewhere, he said. 
 
As the Denali quake's surface waves arrived at Yellowstone, changes in hydrothermal activity first were noted at the 100 Spring Plain hot spring system in Norris Geyser Basin. 
 
"Several small hot springs, not known to have geysered before, suddenly surged into a heavy boil with eruptions as high as 1 meter (about 39 inches)," Smith and colleagues wrote in Geology. "The temperature at one of these springs increased rapidly from about 42 to 93 degrees Celsius (about 108 to 199 degrees Fahrenheit)" and became much less acidic than normal. "In the same area, another hot spring that was usually clear showed muddy, turbid water." 
 
Additionally, some geysers erupted more frequently than normal, while others erupted less frequently. 
 
Yellowstone has more than 10,000 geysers, hot springs and fumaroles (steam vents) and scientists monitored how often 22 of the geysers erupted during the winter of 2002-2003. Eight of the 22 "displayed notable changes in their eruption intervals" after the Denali quake, 10 showed no significant changes and the other four were too erratic in the timing of their eruptions to determine if the quake changed them, the researchers wrote. 
 
Geysers that erupted more frequently following the Denali quake included Daisy, Depression, Plume and Riverside geysers in Upper Geyser Basin and Pink Geyser in Lower Geyser Basin. Geysers that erupted less frequently after the Denali quake included Castle and Plate geysers in Upper Geyser Basin and Lone Pine Geyser in West Thumb Geyser Basin. 
 
Most geysers returned to their normal timing days to months after the Denali quake. 
Interestingly, geysers affected by earlier nearby earthquakes — most notably Old Faithful and Grand Geyser in Upper Geyser Basin — were not affected by the Denali earthquake. 
 
How the Denali quake sparked Yellowstone activity
 
Instead of the strong surface waves from the Denali quake independently triggering Yellowstone's small quakes and changes in geyser activity, Smith believes the Denali quake's waves affected the geysers by changing water pressure in underground conduits or "pipes" that feed the geysers. Such changes — which in some cases would have made hot water "flash" explosively into steam — would have altered the pressure on adjacent faults, triggering small earthquakes nearby. This would explain why the quakes were clustered around geyser basins. 
 
Researchers believe that when the Denali quake waves rippled through Yellowstone, they jarred loose minerals that had sealed some underground hot water conduits, causing some geysers to erupt more often and others less often. 
 
In some cases, that allowed superheated, pressurized water to flow more freely to make geysers erupt more often. In other cases, the rupturing of subterranean mineral seals enlarged the size of the conduits supplying geysers, reducing water pressure so those geysers erupted less often. Smith speculated that yet other geysers remained unchanged because they did not have pent-up gas and water pressure and were not affected by the Denali quake's surface waves. 
 
The Denali quake also generated noticeable water waves in Seattle's Lake Union, Louisiana's Lake Pontchartrain and in swimming pools on the East Coast. It triggered small quakes in California's Geysers geothermal area north of San Francisco, and in eastern California's Long Valley, which, like Yellowstone, is a caldera, or giant volcanic crater created by cataclysmic prehistoric volcanic eruptions. 
 
The Denali quake also triggered a few small quakes in Utah. Smith said it is possible some of those quakes occurred near little-known hot springs along the Wasatch fault at the base of the Wasatch Range. 
The fact that the Denali quake triggered geyser and hot springs changes at Yellowstone raises an interesting question: "Could large earthquakes closer to Yellowstone trigger hydrothermal explosions?" 
Such steam-and-hot water explosions in prehistoric times blasted out a hole that now is Mary's Bay on Yellowstone Lake. One such explosion has occurred approximately every 1,000 years since the glaciers receded from Yellowstone about 14,000 years ago. 
 
However, there is no evidence prehistoric quakes triggered those blasts. Such explosions were not triggered by the magnitude-7.5 Hebgen Lake, Mont. quake in 1959 or the magnitude-7.3 Borah Peak, Idaho 1983 quake. 
 
Nevertheless, a big quake near Yellowstone with its surface waves aimed the right way conceivably might "cause large hydrothermal eruptions," said Smith.

Yellowstone Harmonic Tremors Causing Uplift Under Yellowstone Lake
 
A review of the tremor swarms below Yellowstone Lake and the Lake Outflow data show a correlation between the periods of Harmonic Tremors and the volume of water flowing out of the lake.

This correlation could mean that ground deformation (raising) is taking place under Yellowstone Lake as a direct result of the earthquakes and harmonic tremors ongoing since December 26th.

****(All data devices waterflow and sesmic resumed data feeds late this afternoon, per note below they were offline for several hours)*****

It is also interesting to note that the University of Utah and USGS started taking the web reports from many of many of the seismographs in Yellowstone off-line yesterday afternoon so the general public can no longer view them.

Harmonic tremors have started to show up again tonight (1-1-2009).

Take a look at the seismograph from the YML_EHZ_WY ( Mary Lake, Yellowstone Park, WY ):

http://www.seis.utah.edu/helicorder/heli/yellowstone/Uuss.YML_EHZ_WY.2009010100.gif

Some people are using the argument that a much large swarm occurred in 1985 and there was no eruption.

However, would I be correct in saying that they did not pick up harmonic tremors AND those occurred away from the lake near a fault line and so therefore, these situations are different?

I agree, these also look harmonic:

http://mbmgquake.mtech.edu/earthworm/wavef_disp/RLMT_BHZ_US.2009010200.gif

and from what little I know having read up on this but being no scientist: yes the swarm is unusually shallow, unusually intense, unusually long in duration and it is now accompanied by harmonics. Also the bulge has increased in height three inches a year for the last three years, where previously it had not raised at all.

Hi Elizabeth

Nice to see some of us are staying alert to the possibilities.

Interestingly, there is also abnormal activity around 40 miles south of the lake at Flagg Ranch. This is the only monitor in the Teton range that is showing activity.

http://quake.utah.edu/helicorder/heli/teton/Uuss.FLWY_SHZ_IW.2009010200.gif

After evaluating data by seismic intensity, a very clear picture is emerging of quiet areas of almost no activity to the north and east of the caldera and the area of highest seismic activity (constant harmonic tremors, short interval) on monitors all around the lake edge, going south to Flagg Ranch, extending WNW just beyond the caldera and NE, again just a little ways out of the caldera. Areas of medium activity are, as expected, generally between areas of high and areas of low activity. ALL monitors within the caldera are showing "hot" or "medium" activity.

WHY are no precautionary evacuations being initiated, at least for the park itself? I am reporting from England. My colleagues are as concerned as I am. We have NO media reports on these events over here whatsoever. I can't believe this!

We have JUST seen another swarm of quakes, with 3 quakes at 3.0 and higher inside of 11 minutes.

Check this link:

http://www.seis.utah.edu/req2webdir/recenteqs/Maps/Yellowstone.html

Look at the quake list below. They DO seen to be getting shallower. The magma is moving, possibly upwards.

Watching the data recorders with bated breath and VERY sweaty palms..
