A serious earthquake can be a terrible experience，and it is easy to forget safety measures（措施） in disorder（混乱）． Fortunately，most earthquake safety measures are common sense，but if you forget everything else，remember the following instructions：drop，cover，and hold on．Also，most of earthquake deaths happen after the earthquake，so remember that the danger does not end when the shaking does!

If you stay indoors during an earthquake，move away from unsupported areas and windows．Try to get under a doorway or another area of the building which is held up by strong beams（梁）．Stay under a table or desk only if it is very strong．Do not rush to lifts，because it is far safer to stay where you are．Cover your head with your arms around it and curl （蜷缩） into a ball，and wait for the shaking to stop．

If you stay outdoors during an earthquake，move to an area which is as open as possible．Don’t move to buildings，electric poles and other objects which may fall during an earthquake and injure you．Protect your head and stay low to the ground till the shaking ends and it is safe to move．

After an earthquake，many buildings are less strong，although they appear safe．If you stay indoors，move people from the building quickly and help disabled or injured people．Once outdoors，move well away from the building so that if it falls down，you will not be injured．Wait till public safety officials announce that it is safe to stay indoors．

By planning ahead and keeping calm during an earthquake，you can greatly increase your chances of survival（生存） without injury．
