"EXTRACT FROM DOUG COPP'S ARTICLE ON 'THE TRIANGLE OF LIFE'
I have crawled inside 875 collapsed buildings, worked with rescue teams from 60 countries, founded rescue teams in several countries, and I am a member of many rescue teams from many countries. I was the United Nations expert in Disaster Mitigation for two years, and have worked at every major disaster in the world since 1985, except for simultaneous disasters.The first building I ever crawled inside of was a school in Mexico City during the 1985 earthquake. Every child was under its desk. Every child was crushed to the thickness of their bones. They could have survived by lying down next to their desks in the aisles. It was obscene -- unnecessary.
Simply stated, when buildings collapse, the weight of the ceilings falling upon the objects or furniture inside crushes these objects, leaving a space or void next to them - NOT under them. This space is what I call the 'triangle of life'. The larger the object, the stronger, the less it will compact. The less the object compacts, the larger the void, the greater the probability that the person who is using this void for safety will not be injured. The next time you watch collapsed buildings, on television, count the 'triangles' you see formed. They are everywhere. It is the most common shape, you will see, in a collapsed building."more http://www.davidicke.com/headlines/46512-what-to-do-in-an-earthquake-good-advice
