The Triangle of Life is a controversial theory advocated by Doug Copp about how to survive a major earthquake. It is intended to replace the traditional "drop, cover, and hold on" tactic. 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". Such failures are rare in western communities where opponents argue the drop, cover and hold on tactic will prevent the vast majority of gravity-induced injuries that occur more frequently. [wikipedia]
