Good reminder, Mags, and glad to hear you and your wife are safe. I lived in Boulder and Longmont for many years and many of the photos of the area are hard to see.
The biggest looming threat to the PNW is a big earthquake, although we also have tsunamis, flooding, wildfires, the possibility of a volcanic eruption and now radioactive debris from Japan reaching the coastline. Whew!
I have to admit my own disaster preparedness comes down to having a few gallon containers of water in the garage and thinking I'll be able to access all of my camping/backpacking gear that's in bins there. For earthquakes, I also have good work gloves and a small crowbar in my garage.
Also, here's a link to a pdf for a simple solution to an overlooked problem (going to the bathroom) for anyone that might get stuck, especially in urban areas, for an extended period of time:
