I think Zombie's could happen. In the orignal NIGHT OF THE LIVING DEAD (the best zombie movie IMO) it is explained, I think, a probe returning from venus exploded and strange radiation it brought back is bringing the recently dead people back to life....

I could totally see that happening!!!

I wouldn't worry about zombies, just check your targets though. There is an urban legend that some backwoods militia types made the mistake of watching a DVD of a Romero pic, the night a short bus flipped over on the highway. Well, you had bloodied folks shambling out of the treeline, hittng their chests with the backs of their hands and moaning.

"uh...uhhh."

BANG!


Then there was the poor soul who coughed, sneezed, hiccuped and broke wind all at the same time. Due to the lack of air pressure, he collapsed in on himself to form a singularity. He imploded so hard it took the tailgate off the truck with him. There is still an air-pocket on 79 hiway where the beercans still circle


Two guys once emerged from this during the shortest day of the year-- one man wearing a turtleneck--the other had huge sideburns.

"Same time tomorrow Issac?"

"Same time tomorrow, Carl."


Back on topic. Anyone with interests overseas better pay attention to this

Thank you for the explanations

It could be pretty depending upon what kind of basalt is there. If it is andesitic we could all be sucking dust for a long time. If it is theolitic, which I have read in a paper that I cannot remember, then it may be more like a Hawaii flowing eruption. Either way it would not be pleasant. The whole midwest would be covered in meters and meters of ash.

Given the thickness of the continental crust there's no way that the lava will be basaltic or even andesitic (there would be a lot of magma differentiation and incorporation of the host rock). The Lava Creek tuff from a previous Yellowstone eruption is a rhyolitic tuff so any eruption would be extremely explosive.

I agree, I'll have to dig out that reference. It has to be continental that far inland.

On a related note. Some congressman, worried about the over population on Guam, is really worried, and I mean he's serious, that the island might tip over.

I must have been thinking about the Columbia River basalts. I did enough thin sections of those in undergrad petrology. Here we go,the following was copied from the USGS website.

An additional difference between Yellowstone and Columbia River/Newberry (CR/N) is that Yellowstone's magma is rhyolitic and CR/N's magma is basaltic. Rhyolitic magma is a lot more explosive than basalt, and indeed Yellowstone's eruptions have been among the most powerful observed in the geologic record. (The Huckleberry Ridge tuff, which erupted from Yellowstone 2.1 Ma, is deposited over something like half of the Lower 48!) CR/N, on the other hand, appear to be gentler eruptions more like Hawaii's oozing of basalt. I suppose this too can be explained by Derek's model: partial melting of the more-felsic crust under Yellowstone (as hot plume magma heats that thicker slab of continental crust), but a shallower Moho to the west, producing mafic magma a shorter vertical distance from the surface.

Please, tell us you are kidding. At the very least, tell me he's not from NEW YORK.

Actually there are some plant masses that might actually become 'floating islands' of a sort: http://en.wikipedia.org/wiki/Floating_island

Needless to say, Guam isn't one of them.

I think there was a Voyage to the bottom of the Sea Episode where the Seaview 'sunk' an island
