During an earthquake, you should need to know a thing or two on what to do. If the earthquake strikes while you’re inside a house, you should lie on the floor and take cover under a strong table or other furniture. If there is no furniture you can cover your head with your arms and keep still in the corner of the room. You should remain away from windows, glass walls, or anything that can fall.

If you are in bed, stay still. Hold firmly onto your bed and make use of a pillow (枕头) to safeguard your head. You may use a doorway or shelter but only when it is close to you. It should also be considered whether it is strong enough to deal with the load. Do not use lifts, even when they work. Electricity may go out at any time. Many injuries happen when people try to rush out. This means you ought to stay still in your house or perhaps wherever you are.

When you are outdoors, you should be far away from buildings, power wires or lights. You should be in the open until the quake stops. Remember that many earthquake deaths outside the house come from debris (碎片), falling walls, flying glass and other falling objects. If an earthquake strikes and you are driving, you pull up to the side of the highway and stop as quickly as possible. You ought not to stop under trees, buildings or power wires. Don’t stop in the middle of the street since it could trouble others.

When trapped, you shouldn’t move. Your mouth should be covered with a piece of clothing or handkerchief. Do not shout whenever possible. Shouting should be employed at last to get help from rescuers. This is because it is possible for you to breathe some dirty dust.
