>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 ...

You are, however, right next door to the 3rd most dangerous volcano in the US.

You might be in luck though. Historically, mud flows have tended to go to the west.
