Dunno if this is the right section or not but anyone live near?
Should give the doom sayers something to worry us about besides man made global warming!
I read about it years ago in the readers digest but this is the latest.

The seismologist interviewed on NPR that i heard yesterday was of the opinion that this particular type of swarm does not indicate an imminent eruption. Then again, they haven't quite locked down all the warning signs yet hehe.

If I see a mushroom cloud on the northern sky I'll try to send a warning.

If you read "Man and Impact in the Americas", Chapter 2: Getting to the Crossings, you'll learn that the effects of super-volcanic on man were not as severe as those of the largest asteroid and comet impacts.

A lot of this has to do with the type of particulates, and it should be mentioned that several years ago Russian scientists looked at ways of precipitating those particulates out of the atmospher. Of course, as there's now 6 billion people living on planet Earth, the effects of any supervolcanic eruption today are not likely to be "pretty".

A lot of this seems to be fear displacement activity from the economic and middle eastern mess which we are now in, which can not be discussed in polite company - thus all the nonsense about 2012 as well.

Roy, if you're any good perhaps you can write up a book linking supervolcanic eruption with 2012, go on late night talk radio, and spend the next several years on some tropical beach.

Some of the latest news.
From todays Salt Lake City newspaper

http://www.sltrib.com/news/ci_11409304

The max size of the region is huge.
Yellowstone is on the very north edge.
It covers about 1/3 of the US.
I will see if I find the map.

I think I am starting to hyperventilate.

First the much dreaded yearly ordeal at my ob-gyn's (today!) and now this?!

Excuse me while I go find a paper bag to breathe into!

[kbs2244]

I wouldn't worry about it too much.
It is kind of like the next impact event.
Not much you can do about it.

You have a talent for understatement, kb!

[Leona Conner]

During the "cold war" people around here worried about someone bombing Oak Ridge (just up the road a spell.) Now if this thing blows; according to the maps, we here in Tennessee will be right in the path. I know I should have stayed in Los Angeles, all I had to worry about there -- earthquakes.

[Minimalist]

earthquakes.

Fires. Mud slides. Traffic. Prices. Congestion.

Actually, kb, the next impactor can be diverted away from the Earth with existing technologies. That it can't is a lie promoted by
1) Mars Nuts, who think we have nothing better to spend our money on than flying a few men to Mars
2) Anti nuke folks, who would rather see mankind perish then nukes peacefully used in space
3) NASA, who doesn't really want to handle the problem.

To use the exact word, they're lying to you.

We can always call on Billy Bob and Bruce.
They have some experience.

I just saw something (Science Channel?) which suggests that using a nuke to blast an asteroid would merely result in having a number of smaller pieces bombarding earth and given the relatively small size of the objects which caused Tunguska and Meteor Crater in Arizona this is hardly a favorable outcome.

It is possible to deflect an asteroid by slowing its speed but the key is in early detection - something which could use a lot of work as a pre-cursor to designing a deflection system.

Money well spent in my humble opinion.

I've always had some doubts about that Min, The greater the number of pieces surely the greater the surface area that can oblate during entry, and the lower the surface impact and less ejected material from the surface of the Earth?
Also some must also logically be put into a different orbit?

Hi Min, Roy, kb,

If you go over to Old World, I have posted links to work on impacts over the last 13,000 years. Free reading for cold winter days - I think you''ll find it interesting, and your own insights will probably be interesting as well.

The way you deflect an asteroid or comet is by either using a stand off nuclear explosion, or by using a Solid State Heat Capacity Laser to ablate its surface. The key is early detection, as a small change in direction out there means missing the Earth by several diameters here.

Otherwise you can be sure that everyone will, just throw every nuclear charge they can at one, which may or may not work, depending on size, speed, and a number of other factors.

NASA leadership has been letting us down in dealing with this, with the current NASA Administrator ignoring the explicit instructions of the Congress, but I do have the audacity to hope for a change.

Back to volcanoes, my impression is that generally people have been able to get out of the way, and survive interruptions to food supplies.
