scary that there are so many things on this earth that can kill you. scary that there are tiny things you can't see, and then there are these huge things that can spew scalding hot stuff out and burn you to death. and you can see those, but you don't really know if they are going to go off at any given second. weird. to me, anyway.

This photo really spoke to the tool wielding primate in me. Perched on the brink of oblivion these folks are using the machinery at hand. Its raw emotion and power. Add in the glare effects from the lights and lava and the blur of motion from the whirling Cats and it's just a great photo. The activity is no less primitive than some monkey trying to ease termites onto a stick, these guys are overmatched and they know it but with a little finesse, they might just pull it off.

The only reason we survive at all is that mother nature

I'd like a bigger version of this photo (although I'm sure if you knew where one was you would have posted that.)

Read John McPhee's The Control of Nature for a fascinating account of a small town in Iceland (redundant?) which had to divert the flow of a volcano to avoid their harbor being sealed off. Rather than backhoes, they used gallons upon gallons of seawater. Here are a couple of illustrative photos.

I think the subject says it all.

This is almost surreal. If we didn't really know it was actually happening we might think it was the latest Sci-Fi flick from James Cameron.

Thank Griff for this one, and dasviper for the excellent followup images.

A slightly larger version can be found at the Seattle Times. Its an AP photo by Villa Fabrizio so if anyone knows where to look...

All this talk of volcanoes reminds me of a Geology class I had a couple semesters ago. The teacher touched on something I thought was really cool: How do scientists <b>know</b> that the Earth's core is liquid? After all, they can't get to the center of the Earth. Are they just guessing or something?
Tobiasly Wednesday Nov 27 12:16 PM
That is pretty cool. Technology is awesome. I'm guessing they could then, based on that data, make a pretty decent estimate of the actual size of the liquid core.

I also neglected to mention that when seismic waves go through a material that is a different density than the one it was traveling through before, it refracts the waves, sort of like water refracts light. So that's how they know what the different layers of the Earth are like. Somehow they can calculate the angle of the refraction and figure the density of the new kind of rock.
