For the USC and Exposition Park neighborhoods in Los Angeles
Don't run for the door. A real earthquake will be too violent. Just get under your desk, next to the wall or chair. That will break the full force of anything falling that may hit you.
Most people are injured by falling objects, often after leaving the building.
Tune to KNX 1070 AM radio for a live earthquake drill broadcast to kick off the drill or download the broadcast audio from www.shakeout.org/drill/broadcast/index.html.
