Experts weigh super-volcano risks

I've been telling people about this for years; perhaps this will get their attention. Yellowstone has a history of an eruption about every 600,000 years; it's been 640,000 years since the last one. The article doesn't mention the uplift of Yellowstone that's currently going on, nor about the 1,000 foot tall 'bulge' in the bottom of Yellowstone lake, both very worrisome signs.

As the article says, it's not a matter of 'if', just 'when'.
