汶川地震后余震不断，上网搜注意事项，发现有一篇文章很火，叫做《地震时应该躲在哪里》，说是美国国际搜救队长道格卡普提醒应该在地震时“不要躲在桌子、床铺下，而要以比桌、床高度更低的姿势，躲在桌子床铺的旁边。”在网上搜索了一下，发现有一些质疑的文章，先转一篇，方舟子的博客：http://www.xys-reader.org/blogs/fangzhouzi/?p=9330

至少美国官方提供的材料没有推荐这样做，来自FEMA（美国联邦紧急措施署）：

What to Do During an Earthquake

Stay as safe as possible during an earthquake. Be aware that some earthquakes are actually foreshocks and a larger earthquake might occur. Minimize your movements to a few steps to a nearby safe place and stay indoors until the shaking has stopped and you are sure exiting is safe.
If indoors
DROP to the ground; take COVER by getting under a sturdy table or other piece of furniture; and HOLD ON on until the shaking stops. If there isn’t a table or desk near you, cover your face and head with your arms and crouch in an inside corner of the building.
Stay away from glass, windows, outside doors and walls, and anything that could fall, such as lighting fixtures or furniture.
Stay in bed if you are there when the earthquake strikes. Hold on and protect your head with a pillow, unless you are under a heavy light fixture that could fall. In that case, move to the nearest safe place.
Use a doorway for shelter only if it is in close proximity to you and if you know it is a strongly supported, loadbearing doorway.
Stay inside until shaking stops and it is safe to go outside. Research has shown that most injuries occur when people inside buildings attempt to move to a different location inside the building or try to leave.
Be aware that the electricity may go out or the sprinkler systems or fire alarms may turn on.
DO NOT use the elevators.
