How much of a threat is it there? Portland's sounded like an attractive place to try to move to, having the best bicycle transport "infrastructure" in the country. Seems like the side-effects like mudslides are worse than the direct effect of the earthquakes themselves in that region. I moved back from Japan just a few months before the 2011 disaster.
