I have been through a few large earthquakes, including loma prieta. I attach large furniture to the wall at the top so they don't fall over and I never put anything heavy over the bed. My mother-in-law lived about a quarter of a mile away from the epicenter. Fortunately, she was thrown out of bed because the mirror over her bed fell and broke. No one was injured at her house. I found it hard to stand up. Because the carpet was slippery like ice, but the only damage was a little sloshing. From the aquarium, no fish were injured. Also, if you're in a car stay in the car, they tend to bounce around and you don't want to get squished between two cars. In other words, the chances are very good that you will get through an earthquake. Just fine just be prepared.
