Oregon isn't as earthquake prone as California, but once it became clear that we're due for a powerful subduction zone quake of approx 9.0 on the Richter scale, we began keeping earthquake supplies in each of our vehicles and we have stored old camping gear, old clothes, food, water and various odds and ends on our property where they would probably be accessible even if our house became unsafe to enter. We'd still be miserable if it happened in winter, but we'd scrape by for several weeks.
