生命三角理论（Triangle of Life）是由道格·库普（Doug Copp）所提出的争议性地震逃生理论，此理论与大多数公信力机构所提倡的防震建议背道而驰，其理论声称：「在大地震来临时，人们可以躲进由坚硬物品及坍塌物所产生的三角形保护空间（即生命三角），以避免人员因建筑主体结构如一张大饼般平塌（pancake collapse）造成伤亡，并建议不要躲在桌子底下。」
****消防署、美国国土安全部及许多国家具公信力的机构并不采信生命三角理论，并建议民众于地震发生且在室内时,遵循地震保命三步骤才可以有较高的生存机率，其三步骤为：

The Triangle of Life is a controversial theory about how to survive a major earthquake, typically promoted via viral emails. The theory advocates methods of protection very different from the mainstream advice of "drop, cover, and hold on" method widely supported by reputable agencies. In particular, the method's developer and key proponent, Doug Copp, recommends that at the onset of a major earthquake, building occupants should seek shelter near solid items that will provide a protective space, a void or space that could prevent injury or permit survival in the event of a major structural failure, a "pancake collapse", and specifically advises against sheltering under tables.
