阅读下面短文，简略回答问题。
Earthquakes may happen in some areas every year. How can we save ourselves when an earthquake happens? Remember the following advice that can keep you safe.
Leave quickly
Leave the building quickly when the ground stops shaking. Don’t use a lift (电梯). It may be very dangerous. You should be careful and try not to fall down when you go downstairs. Accidents may happen when many people rush onto crowded stairs. Remember to run to an open area away from street lights and power lines.
Find a safe place
If you can’t leave a building in time, you should hide yourselves under a table and stay away from windows. If you are in a bus or car, stay inside it. If you are in the mountains, be careful of falling rocks.
Value lives
Some people care too much about valuable things. If you spend your time collecting these things, you will lose the best chance to run away. Anything is less valuable than your lives.
Keep calm
When you are caught in a building, you should keep calm. Don’t shout all the time. You should save your energy and try to find some food and water.
