Īlso, given that there are no warnings for earthquakes, a person is more likely to be injured trying to move during an earthquake rather than immediately seeking a safe space by furniture, or near an interior wall, not doorways, as they are often not structural. Statistical studies of earthquake deaths show most injuries and deaths occur due to falling objects, not structures. It is also argued that this movement means that lying beside heavy objects is very dangerous. Critics have argued that it is actually very difficult to know where these triangles will be formed, as objects (including large, heavy objects) often move around during earthquakes. Criticisms Īccording to the United States Geological Survey (USGS), the Triangle of Life is a misguided idea about the best location a person should try to occupy during an earthquake. Such triangles are the most common shape to be found in a collapsed building. The larger and stronger the object, the less it will compact the less it compacts, the larger the void next to it will be. Copp terms this space for survival the "triangle of life". Īccording to Copp's theory, when buildings collapse, the weight of the ceilings falling upon the objects or furniture inside tends to crush them, but the height of the object that remains acts as a kind of roof beam over the space or void next to it, which will tend to end up with a sloping roof over it. Officials of many agencies, including the American Red Cross and the United States Geological Survey, have criticized the "Triangle of Life" theory, saying that it is a "misguided idea" and inappropriate for countries with modern building construction standards where total building collapse is unlikely. 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.
The theory advocates methods of protection very different from the mainstream advice of "drop, cover, and hold on" method widely supported by reputable agencies.

The Triangle of Life is an unsubstantiated theory about how to survive a major earthquake, typically promoted via viral emails. Most fatalities are caused by falling objects, against which the "Triangle of Life" method is ineffective.
