Thats the unfortunate thing about living in Mountainous places, or along Tectonic Plates. Earthquakes are one of those things we never really think about until after they happen. I remember as a kid we used to do earthquake drills almost once a week, and then it stopped for some reason. But there is still a very good chance of Major Earthquakes happening here, since we're only a stones throw away from the Yellowstone Supervolcano, which averages between 1000-3000 Earthquakes of a Magnitude 1.0-4.0.
