The number and frequency of earthquakes in the Yellowstone Park area is increasing every day:

link.

"CHEYENNE, Wyo. (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."

Might be a good time to check your dust mask collection.

If you live on the East Coast. smirk

What kills me is this changes nothing about whether they can say something more will happen or not.

One big tell is that most of the activity is at the Northwest end of the Caldera. That is the leading edge of the suspected hot spot, and would seem to indicate more than anything that something bad may be coming. The tec plate moves west to east, so the east side of the caldera used to be over the hotspot. Had the storm been on the east side, it would've been more indicative of subsidence, but on the Northwest portion, it likely means the hotspot may be agitating.

Yeah, I can use conditionals just like the pros.

So what you are saying is it just might be a definite maybe?

Umm, could be. Then again it might not.

My question is, statistically how much of a variation from the norm over the past.. 20-30 years is this?

My other question is, other than don't breath the portland cement if you can avoid it, what do people expect to do during the ashfall?

Oh well, if it does pop, it should help take care of global warming for a while.

Imminent Yellowstone ‘Supervolcano’ Now ‘Unlikely’

NEW YORK (CBS) ― The recent “swarm” of small earthquake tremors happening in Yellowstone National Park are not likely to be a sign of a pending “supervolcano” eruption as some fear, according to a top scientist at the Yellowstone Volcano Observatory.

There is also this brief article in Scientific American that comes to similar conclusions (though it also points out that nobody can be absolutely certain):

http://www.sciam.com/blog/60-second-scie...e-ye-2008-12-30

Also, if your are interested, and perhaps only someone in Chris Kavanaugh's field would be, there is also an article on Scientific American's website -- that reports on research that has appeared in the journal Science -- about a North American meteor or comet strike. This strike could be an explanation for the die-off of the Clovis people as well as North American Mega-fauna. Most importantly for me, after reading this article, I can now say "nanodiamonds".

Since eruptions are tens to hundreds of thousands of years apart, depending on the size, I'm not sure such short time periods of 20-30 years are meaningful.

Probably wonder how much uncontaminated drinking water will remain west of the Mississippi in 72 hours...

I'm not sure the a 20-30 year record is terribly meaningful either- I just don't know if we have good, 24/7 logs of the activity there that goes further back. If we do, GREAT! Let's throw that into our analysis.

I know our numbers are very short term no matter what, but you decide your actions based on the data you have at the time. *shrugs*

Ancient irish warriors of my matrinlinear family created the family crest of a guy on horseback riding through the surf to escape his enemies. The truth is found in other accounts of celtic warriors attacking enroaching seawater on horseback with drawn swords.
I figure, if I'm at Yellowstone and anything happens I'll just stand with my RSK in hand and tell the forces of nature to knock it off, eruptions not in the brochure from AAA.
Meanwhile, last night had a lovely porgramme on Yellowstone in winter, including the narrater spending the night in a blizzard with a -20 rated down bag and a tarp shelter. He woke up to his film crew asking how he did.His comment, interrupted by deafening winds, was on flapping of his tarp kept him awake.
He then observed John Coulter only had a buffalo robe and probably slept better.
I must practice making my tarp knots tighter to reduce flapping and increase resistance to volcanic ash.ROTSLOL
