>>Yellowstone is about 500 miles, as the crow flies, from Ellensburg. I've read articles about Yellowstone's super volcano potential, spewing "a cloud of plant-killing ash would fan out and dump a layer 10ft deep up to 1,000 miles away". However, we wouldn't be downwind, so we'd most likely get nothing blown our way. I would also think that, being 500 miles away, earthquakes wouldn't be too bad either. We'd probably be ok ...

Yeah, I was going to mention Rainier. I don't think we'd need to worry about mud flows, but we'd most likely get a lot of ash if it ever blows. I didn't live here when Mount St. Helens blew, but there was plenty of ash here in Ellensburg (and even more in Yakima). And we're closer to Rainier than St. Helens.

But, I'd say you are probably too close to Yellowstone.
