I live in California. It's a ticking time-bomb, and the result isn't going to be a tipped-over styrofoam cup. I'm ready to hide under the counter in such an event to avoid exploding glass. The last large-ish earthquake we got was in October a few years back. It felt and sounded like someone fired a cannon under the foundation.
Yes I am bragging about the uber-badas earthquakes we get.
