Yellowstone might go on first stage alert soon.

Since January 17, 2010 Yellowstone has had the second largest swarm ever recorded. The swarms have been steady at about 10 miles in depth and they have subsided a few days ago.

In the past two days the depth has raised up to around 7 miles and in the past couple hours quakes vastly increased.

Remember this doesn’t mean we will see an eruption and it most likely means a normal volcano. It is very unlikely we will see a caldera eruption.
But these changes are significant and cannot be over looked

Some history:
Since the most recent giant caldera-forming eruption, 640,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Of these eruptions, at least 27 were rhyolite lava flows in the caldera, 13 were rhyolite lava flows outside the caldera and 40 were basalt vents outside the caldera. Some of the eruptions were approximately the size of the devastating 1991 Pinatubo eruption in the Philippines, and several were much larger. The most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau, occurred 70,000 years ago.

Frantzie,

SatinDoll meant her post #638 for you (not me).

Oh, so sorry I sent it to the wrong address. Must be old age...

[ETL]

Lol! That’s OK.

On the other hand, we are all youngsters compared to the Yellowstone Hot Spot! :)

If the caldera blows, all of our present worries are over.

[Unrepentant VN Vet]

I’m about 90 miles north of the Park, so if she blows, I probably won’t have time for the last half of the “Oh, ****!”.

....does seem to be an awful lot of fuss to get one little old sinner like me, though.

[Frantzie]

I wish the caldera was very close to Chicago and the white hut.

If this blows it should fix unfunded liabilities in most states.

[Frantzie]

Sh*t poor old dinosaurs. La Garita 100,000 megatons?!

bttt

[Errant]

Thanks for the ping. Things are getting more active in Iceland as well.

Many more Iceland volcanoes seem to be stirring

[Quix]

HMMMMMMMMMMMMM THANKS.

[Steve Van Doorn]

It doesn’t seem to be a great deal of pressure in my opinion at YMR. I don’t expect a huge event at Yellowstone with this swarm, but things could change.

[bog trotter]

Run? Which way!
We had a teensy one here in MI once and our chickens and horses ran in CIRCLES.

[Smokin' Joe]

Nope. Can’t erupt. The EPA hasn’t issued a permit. That settles that. Move along, now, folks...(/s, as if...)

[GregB]

Would I love to go back to Yellowstone!!!

sorry, only democrats vote in their after life.

[Steve Van Doorn]

yellowstone YMR area is acting really odd. The last few days the quakes were at under 5 km now they are down PAST the level they started around at a months ago when the swarm started and it has picked up in frequency. They are now at 11 km down.

I can only assume it is a new wave coming up it is something to keep an eye on.

[winoneforthegipper]

YMR has been down for me since yesterday....

But there were a few today located on the other webicorders in the area.

[Steve Van Doorn]

yes, it is down today but as you said you can view it on other locations.

Costa Rica just had a 6.2. Cocos plate.
