Disasters happen all the time somewhere in the world. Are you ready if one hits your neighborhood next week? Find out what you need to do now before it is too late. Let’s take an earthquake for example.

During an earthquake, get under a strong object like the kitchen table. Don’t leave the building during the shaking, or you might be hurt by falling objects from the outside of the building.

When you are in bed during the night and an earthquake happens，simply roll off the bed. There will be a safe void around the bed.

If you are watching TV and you cannot easily run away by getting out through the door or window, then lie down and curl up(蜷伏) next to a sofa, or a large chair.

Never go to the stairs. The stairs are likely part of the building to be broken. Even if the stairs are not destroyed by the earthquake，they may fall down later when people run down.

Try to get into an open area away from trees，buildings，walls，advertisement boards and power lines if you are outdoors.

If you are driving when an earthquake suddenly happens，just stay in your car until the shaking ends. However, if the footbridge falls and breaks your car，get out of it and sit or lie next to it. All the broken cars have voids 3 feet high next to it.
