This guy dutchsinse really knows his stuff. His video reportings are excellent IMO.
He demonstrates just how large the Yellowstone magma pool under the earth may be beyond what has been reported by those who have recently measured it. And, how very connected the western U.S. volcanos appear to be.
I think that after all that I have learned today, I will go into deep meditation and get centered.

Hi Snowbird!
dutchsinse may know his stuff; however, it's only "his" as in the root of the word "idiom."
If he really knew a tiny bit about geology, he would know that the chemistry of the magmas underlying Yellowstone and the volcanoes of the Cascade Range are widely apart. Right there, and with only that, is the indication that the magma chambers have no connections.
These magma chambers are generated by totally different processes. Yellowstone is considered a mantle plume just as Hawaii is. The Cascade volcanoes are a result of the melting of subducted materials under the North American Continent.

Hence, I suggest you do a little Googgling of your own and check out some of the dutchnonsinse.
He demonstrates just how large the Yellowstone magma pool under the earth may be beyond what has been reported by those who have recently measured it. And, how very connected the western U.S. volcanos appear to be.
Here is another trouble, dutchsinse doesn't demonstrate anything; he just exposes his theory on the subject with the material from his mind (his own) without any respect to known data. Just consider that, in order to join Yellowstone to the seafloor volcanoes, there is a subducting plate to cut across.
His video reportings are excellent IMO
A good doom and gloom presenter... I agree! This guy is doing as much damage to true understanding with his well presented nonsense as does the 2012countdown guy with his bubbles/lava tubes.
You want something really scary to contemplate in your meditations? Consider this: the whole, complete, entire Earth crust --continental + oceanic -- is just floating around on a ball of molten rocks... has been so since Earth terraformed. Volcanoes and mantle plumes just get out through a path of least resistance.
Hope this helps in your reality-based quest for truth?

Which dutchsinse didn't seem to have read or understood as it states:
The resulting picture suggests that the molten rock of the mantle plume seen in seismic images is only the core of a much larger volume of hot crust. Although this area isn't molten, the high temperatures allow water to pick up elevated levels of salt, which enables its detection through the MT monitoring equipment. The plume itself seems to slope down a bit more gently, and extend much further under Idaho than the seismic data had suggested. The MT data also confirms suggestions that the rock within the plume doesn't become molten until it reaches a depth of about 250km.

Amzer Zo - If he really knew a tiny bit about geology, he would know that the chemistry of the magmas underlying Yellowstone and the volcanoes of the Cascade Range are widely apart. Right there, and with only that, is the indication that the magma chambers have no connections.
It doesn't require a geologist to recognize that I am not one. However, I find earthquakes and volcanos really interesting to study on a casual basis and from a distance. After reading a few sites about Yellowstone and its connections to the Snake River Plain which not only is the site of seven ancient calderas starting with the oldest or McDermitt Volcanic Field in the northeast corner of Nevada and ending with the youngest or Yellowstone, I found that this very area is where scientists have discovered the extended plume of molten rock. I also read that the concept of mantle plumes is scientifically controversial.

Well, I have to agree that dutchsinse is demonstrating his own opinion and states that somewhere within the video. I was not implying that he is geologically scientifically trained. I admire the work of many people who have no training whatever in the areas they produce. His credentials are not the point. The point, is that he made the effort to share information that we should all be aware of. And, certainly not fear. And, I don't consider this subject as doom and gloom. We have known about the possibility of the Yellowstone supervolcano for years. We are simply learning more about it. Knowledge is powerful even though it may or may not stem from one who is certified or licensed. The reason that we have these discussions on line is to learn from one another.
How do we know that there exist no arterial flows connecting these areas, such as bluestflame mentioned? Granted, I also thought it a stretch as dutchsinse attempted to connect the oceanic volcanos with those on land, but stranger things have happened.

Yellowstone Detectives Find Underground Column of Molten Rock
A plume of molten rock rising from deep beneath Yellowstone National Park is probably what is fueling the region's volcanic activity, as well as tectonic plate oddities across the Pacific Northwest, new research suggests.
Debates have long been waged over whether erupting and shaking in the area over the last few millions of years — and a track marked out by a chain of volcanic calderas along the Yellowstone Snake River Plain in Idaho — could be the work of a column of hot rock rising up from deep within the Earth's mantle. The mantle is the layer of hot, viscous rock beneath the planet's crust.
The plume is thought to be more or less stationary, with the North American plate — and the Juan de Fuca subducting beneath it — slowly sliding southwesterly over the plume. So what is now Oregon probably sat where Yellowstone is today about 17 million years ago, baking and breaking over a hot plume of rock, Camp said.

I also read that it is possible that the state of Oregon could have been positioned where Yellowstone is currently, seventeen million years ago. That's a lot of repositioning of the earth's crust over time. Which makes one wonder just whether or not the plumes of molten rock remained stable or traveled. There are ancient extinct calderas all over the U.S. There is at least one in New Mexico and another about 15 miles from Mt. Baker in Washington state, which was a supervolcano. Many of these extinct volcanos are not easily visible.

Good search job Snowbird!
Let's start with the ancient lore about wandering volcanoes:
During their voyages, sea-faring Hawaiians noticed the differences in erosion, soil formation, and vegetation and recognized that the islands to the northwest (Niihau and Kauai) were older than those to the southeast (Maui and Hawaii). This idea was handed down from generation to generation in the legends of Pele, the fiery Goddess of Volcanoes. Pele originally lived on Kauai. When her older sister Namakaokahai, the Goddess of the Sea, attacked her, Pele fled to the Island of Oahu. When she was forced by Namakaokahai to flee again, Pele moved southeast to Maui and finally to Hawaii, where she now lives in the Halemaumau Crater at the summit of Kilauea Volcano. The mythical flight of Pele from Kauai to Hawaii, which alludes to the eternal struggle between the growth of volcanic islands from eruptions and their later erosion by ocean waves, is consistent with geologic evidence obtained centuries later that clearly shows the islands becoming younger from northwest to southeast.... and the earliest contemporary idea about a plume:

J. Tuzo Wilson's original diagram (slightly modified), published in 1963, to show his proposed origin of the Hawaiian Islands. (Reproduced with permission of the Canadian Journal of Physics.)
I found that this very area is where scientists have discovered the extended plume of molten rock. I also read that the concept of mantle plumes is scientifically controversial.
Yes, indeed, the plume theory, even with Hawaii, was well into a coffin and nailed in... but, the fiery Goddess Pele resurrected and kicked that coffin lid off and away:
Hawaiian Hot Spot Has Deep Roots
ScienceDaily (Dec. 3, 2009) — […] Now, a sophisticated array of seismometers deployed on the sea floor around Hawaii has provided the first high-resolution seismic images of a mantle plume extending to depths of at least 1,500 kilometers (932 miles).
"This has really been an eye-opener," says Solomon. "It shows us that the anomalies do extend well into the lower mantle of the Earth."
Has the question of hot spots and mantle plumes been settled at last? "We believe that we have very strong evidence that Hawaii is underlain by a plume that extends at least to 1,500 kilometers depth," says Solomon. "It may well extend deeper, we can't say on the basis of our data, but that is addressable with global datasets, now that our data have been analyzed. So it's a very strong vote in favor of the plume model."

I totally agree that knowledge gives one more control/power over doom and gloom. My concern with the dutchsinse video is that he presents the diagram as a plume of molten rocks rather than of hot, salt saturated fluids (see original article).
For Yellowstone, here is the most recent seismic model (2009):
6955
Caption: Seismic imaging was used by University of Utah scientists to construct this 3-D picture of the Yellowstone hotspot plume of hot and molten rock that feeds the shallower magma chamber (not shown) beneath Yellowstone National Park, outlined in green at the surface, or top of the illustration. The Yellowstone caldera, or giant volcanic crater, is outlined in red. State boundaries are shown in black. The park, caldera and state boundaries also are projected to the bottom of the picture to better illustrate the plume's tilt. Researchers believe "blobs" of hot rock float off the top of the plume, then rise to recharge the magma chamber located 3.7 miles to 10 miles beneath the surface at Yellowstone. The illustration also shows a region of warm rock extending southwest from near the top of the plume. It represents the eastern Snake River Plain, where the Yellowstone hotspot triggered numerous cataclysmic caldera eruptions before the plume started feeding Yellowstone 2.05 million years ago.
6956
Caption: This is a cross section of the plume of hot and molten rock that tops out about 50 miles beneath Yellowstone National Park, and tilts downward to the northwest to a depth of at least 410 miles. The plume is mostly hot rock with about 1 to 2 percent molten rock. Researches believe "blobs" of hot rock slowly detach from the top of the plume and rise upward to recharge the magma chamber that lies from 3.7 to 10 miles beneath Yellowstone. The chamber is also mostly hot rock, but with a sponge-like structure containing about 8 to 15 percent molten rock.
I also read that it is possible that the state of Oregon could have been positioned where Yellowstone is currently, seventeen million years ago. That's a lot of repositioning of the earth's crust over time. Which makes one wonder just whether or not the plumes of molten rock remained stable or traveled. .
… a preliminary study by other researchers suggests Yellowstone's plume goes deeper than 410 miles, ballooning below that depth into a wider zone of hot rock that extends at least 620 miles deep.
They saw overlap, between the zones within the Earth where eruptions originated near the Oregon-Idaho-Nevada border and where the famed Columbia River Basalt eruptions originated when they were most vigorous 17 million to 14 million years ago.
Their conclusion: the Yellowstone hotspot plume might have fed those gigantic lava eruptions, which covered much of eastern Oregon and eastern Washington State.

There are ancient extinct calderas all over the U.S. There is at least one in New Mexico and another about 15 miles from Mt. Baker in Washington state, which was a supervolcano. Many of these extinct volcanos are not easily visible

These are the current recognized hot spots/plumes world wide. What's known with certainty is the relative displacement between crust and plume. What's unknown is if the plumes are totally fixed as in the 19 degrees latitude thing or wandering as in the shift of the magnetic poles would indicate. To be resolved.
My opinion on the Yellowstone threat is that it would be less explosive (but still catastrophic) than at the time of the original formation of the caldera, simply because the channels are already in place which wasn't the case at the time of the first intrusion. Now, in the case of a new crustal shift with respect to mantle, that would be another story... because that would require another outlet to be punched through.
Hope this helps clarify the matter better?
