I live in an area with alot of faultlines but for the most part their "dormant" so when we get a quake we feel it. I will never forget my first one. 4 AM and it was as if a large freight train was running right through the area. (vertical rather then horizontal shaking) It even sounded like one. Once it stopped we turned on the lights and checked the damage. Suprisingly little had been damaged. My sisters vanity mirror had jumped up in the air, flipped 360 degrees, and landed on the carpet leaning against her bed with nary a scratch.
