     Many earthquakes (地震) happen without warning, so it is important to know what to do wherever you

are during an earthquake. Here are some top tips on how to stay safe in an earthquake. 

    ◆ Keep a cool head. Worry may make bad decisions. Think about what you should do. The first several

seconds are important. 

    ◆ If you are indoors during an earthquake, hide under a heavy desk and protect your head. Stay away from

windows and anything that could fall on you.

    ◆ If you are in a crowded hall away from the door, don't rush to the exit. You will find too many people

trying to get out at the same time. Instead, hide under a desk or a table. Do not get into a lift during an

earthquake!

    ◆Stay in a safe area until you are sure it's OK to leave. Some aftershocks (余震) may follow an earthquake.

These are as dangerous as the earthquake. 

    ◆If you are at home and you smell gas, open a window and leave the building quickly.

    ◆ If you are outdoors, find a clear place away from buildings, trees, street lights and power lines.

    ◆If you are buried in debris (埋在废墟), you may make noises by knocking at the rocks. Shouting will use

up your energy. You could be without help for up to 72 hours. Try to find some water and food. These are

important for you.
