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.
I’ve got three baby food jars full of Mt. St Helens I collected from my front yard when I lived in Spokane - 350+ miles away from the mountain.
The sky turned dark in the middle of the afternoon. Street lights were controlled by photo-cell switches and the lights came on at 3pm. The birds and dogs fell silent then all of a sudden the only sound heard was a soft hiss as the ash began to fall.
it isn’t over until the fat lady stops singing.

LOL...yeah, we had her in the green room a few times already.
Did you notice that guy on youtube who is posting like their is a conspiracy going on with the UTAH geologists in not giving out the right information regarding this swarm?
I hope he’s wrong!....lol!
I'm on the coast of Maine - but I still remember the summer that wasn't - after Pinatubo let go in the Philippines.
And I have a lamp made from Mt.St. Helen's ash.
I'm not liking this.
Boots - that is a mighty fine memory. I’m glad I mentioned the sea shells.
I was within 10 miles of Mt. St. Helens the day before it blew. I think nearly 50 people died in the vicinity. Something 500 times as big would kill thousands at the least. This is even considering the fact that Wyoming, eastern Montana, western South Dakota and Nebraska are sparsely populated.
I’m not real knowledgeable about volcanos. I live in the northwest and got to see Mt St. Helens go but I can’t say I understand enough about vulcanism to be anything more than an onlooker. Still, when the movement rises from 10 km to 0.5 km in a few days I have to worry. Someone on here already said that the shallow movement was probably steam and I have no reason to doubt that but what made the steam move hard enough to cause an earthquake?
You are bad! I’ll tell her you said that!
You suppose that ash layer is that grey layer we see in limestone cutouts on our way to work on 1431 and 360?
Yes a swarm is a series of small earthquakes that means lava is moving underground. In this case it seems to be moving closer to the surface. From 10 to 7 miles depth. I’ll be back tomorrow with some data from the Pinatubo eruption, the book “Volcano Cowboys” has a lot of detail. Also look for increased activity at times of the full and the new moon. We have just had a full moon.
My grandmother brought back some. In the last 3 decades it’s gotten lost.
Bookmark (again) to pick up reading here.
¿¿¿ Might be..... There are a lot of places I've seen that grey stuff.
IIRC correctly lots of little shakes in the ground due to magma movement.
Yep, if such happens the USA will have to commission a new flag cause a goodly number of states will cease to exist as far as human habitation goes.
(Too bad Washington DC is so far away from Yellowstone...)
I suppose it would be worse then a nuclear bomb. Ah well, can’t do anything about that, just pray and leave it in the hands of God.
