Yellowstone super-volcano has a different history than previously thought

“...propagated northwestward.”

Not sure how much credence I give to an article that can’t get cardinal directions right.

[ETL]

Not only do the subducted plates move,

Here, I believe they're talking about a section of an ancient oceanic plate which had apparently snapped off long ago but still, presumingly under its own weight, continues sinking (subducting) beneath the NA Plate.

[ETL]

I never bought the plume theory either.

Why not? Just a hunch?

[Lazamataz]

Correct. Any Yellowstone eruption needs a federal permit to cross any state borders.

Not only do the subducted plates move, but they have changed where our states are located. Oregon, Idaho, and Wyoming are now in the Midwest. People in Chicago, St. Louis, and Minneapolis need to keep an eye out for new volcanos in their neighborhoods.

And there is this, too: "The process started at the Oregon-Idaho border about 16 million years ago and propagated northwestward, forming a line of volcanoes that are progressively younger as they stretched northwest to present-day Wyoming," Zhou added.

Hhmmm...I’m sitting about where that black arrow points right now..

I think Zhou needs to put sticky notes on the sides of her monitor labeled "East" and West".

Wow...missed that one. Guess I was laughing too hard at the “Midwest” idiocy.

[Chickensoup]

since when?

Lol! I just now caught what you two are referring to.

"The process started at the Oregon-Idaho border about 16 million years ago and propagated northwestward"

You a re going to have to get off your butt in a few billion years. Keep your bug-out bag fresh.

At first I thought she perhaps got confused over the direction the *plate* is moving vs the direction the trail is moving. But then realized the plate is moving to the southwest, not northwest.

[sphinx]

Yes, any day now, but women and minorities will be most affected so I’m not going to worry about it.

[IYAS9YAS]

since when?

Not sure what you're asking. I was just pointing out the article writer wrote something was moving northwest when it's clearly northeast.

[rockrr]

"This evidence was in direct contradiction to the plume model," Zhou said.

Wait, what? And all this time they've been telling us the "Science Is Settled™"?!!

[onedoug]

I may be wrong, but there is only one plume system to my immediate knowledge, and that’s Hawaii. Thus I’d find it odd for one to be so far in from the western continental margins, which have definitely demonstrated active tectonic activity over the past several hundred million years.

Rather, it’s plausible that some or most of Yellowstone’s heat sources are remnants of these earlier - and ongoing - subduction systems...but I’d have to review the geology and geophysics of the region to be more sure.

[ETL]

Iceland is a combo plume + sits atop a spreading center.

[ETL]

Iceland is above a plume + sits atop a spreading center. The spreading center supposedly drifted over the plume.

Just move your mouse a little bit and you get a different black arrow.
There.
Safe again!!
Any other problems?
