that the best strategy for earthquake survival could also be different, however for the United States, "Drop, Cover, and Hold On" is recommended. An Iranian peer-reviewed article analyzed and compared both methods in detail, considering their application, the extent of people who are under the coverage, simplicity in transferring concepts, and the probability of reducing casualties and damage in developing countries such as Iran. It argued that "Drop, Cover and Hold on" was useful advice for people who experience smaller earthquakes without total building collapse, which is the vast majority of earthquake survivors. It found that the "Triangle of life" theoretically could be a better strategy during larger earthquakes in buildings with a skeleton (wood or concrete) during a building pancake-type collapse, but acknowledged the possible problems of large objects shifting and crushing the person from horizontal movement, inability to predict which side of an object would create a survivable space, and that the triangle of life method is also difficult to teach and communicate. It concluded that the "Triangle of Life" could harm individuals who attempted to follow the advice in buildings that did not collapse. Neither strategy was useful for the majority of the population in rural Iran because of the mud-brick architecture which has no structure. Based on the simplicity of teaching and the fact that 12,000 times more people are affected by smaller earthquakes and injured, they concluded that "Drop, Cover and Hold On" is still regarded as a better option for people during an earthquake. Testing In 1996, Copp claims to have made a film to prove this methodology and to have recreated a model school and home, filling them with 20 mannequins. The buildings were collapsed by earthmoving equipment that knocked the supporting pillars out. Half the mannequins were in "Duck and Cover" positions and the others in Copp's "Triangle of Life" positions. When Copp and his crew re-entered the building after the blast, they calculated that there would have been no survivors among the mannequins in "Duck and Cover" positions, but 100% survival for those hiding in the triangles beside solid objects. Copp is categorical about the importance of this technique, saying "Everyone who simply ducks and covers when buildings collapse is crushed to death – every time without exception." However, a critic of Copp has stated that this was a rescue exercise rather than an experiment. Additionally, the exercise did not simulate
