Cap on the kettle

" that it's where it is now, there is considerably more mountainous mass overhead, so hopefully major eruptions will happen less frequently." -torquewrench

Less frequently... yessss... then, when it blows, it will be all that much more powerful for having been capped, with lots more stuff to blast into the upper atmosphere when it does.

(And won't those solar panels work great covered with ash in a long volcanic winter!)

Srsly u guyz: torque, I hadn't heard of Yellowstone's possible migration. (Thanks.) I had heard that "they" think Madrid's source (whatever) had drifted a bit, West IIRC. A little closer to me, oh joy!
