Last night on the History Channel, "How the Earth Was Made", they had an episode on Yellowstone National Park. I picked up more info then I had before and it looks scarier than I thought. In 2006 they discovered a hugh reservoir of molten lava under the previous known reservoir that extends hundred of miles. An indicator of activity before an eruption is a spike in earthquakes which was experienced earlier this year; 4 times the normal number of earthquakes. Also a rise in the earth is another indicator. A boat that had sunk a hundred years ago has resurfaced, an indicator that the ground is rising under the lake where the volcano is located.
The real surprise for me was that the hotspot has had a continual history of eruption, not just the last three times but many times. The last three have 600,000 years between eruptions. It has been 640,000 years since the last major eruption. On a regular basis about every million years it erupts and has a track going back hundreds of miles. The hotspot is not moving but rather the geologic plate (North American Plate), is moving over the hotspot.
All this doesn't bode well.
The link above will take you to the website. However, the particular episode is not featured. Maybe later.
I record this series, so I'll get to this episode eventually. It's a great show.
As for Yellowstone, I'm not horribly concerned about it blowing any time soon. It may be "about" to erupt, but in geologic time frames, that really doesn't mean much for the average person. It could happen tomorrow, but it could also happen in the year 3200 and it would still be in the right time frame...
I visited Yellowstone Park in 1957. I witnessed a small plane crash in the park and also somebody got to the blue hole before we got there and put soap suds in the water. It was really bubbling.
In 1960, we had members of our church that visited Yellowstone and they were in the midst of a major earthquake in the park. Luckily, they were not hurt, but everyone was really concerned about them.
My parents and sister went to the park in 1988 during the major forest fire.

Yes, the boat was a steamship brought on to the lake in the 1920's. After a mishap it sank to the bottom of the lake never to be seen again until recently with the uplift of the bottom of the lake due to volcanic activity, or at least a bulge in the mantel due to pressure. It was featured on the program last night. I recorded the show and sometime I'll play it back and see if I can get the name for you.
Yea, the rest of us would be back in the Stone Age. No cars, no tv, no internet, no space program, no science, no doctors, no law---every man, woman and child on his own. Survival of the fittest!!! Might wind up being like Native Americans. I can say that, I'm Cherokee and Chickasaw. Partly. In a 1,000 years, the United States would be liken to Atlantis, or the fallen Roman and Greek Empires.
