Experts' Expert: Where to go during an earthquake (if you want to survive)
Doug Copp's credentials which lead me to call him an expert on earthquake survival: "I am the Rescue Chief and Disaster Manager of the American Rescue Team International (ARTI), the world's most experienced rescue team."
More: "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."
Below, his earthquake survival guide.
Where To Go During an Earthquake
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.
10 Tips for Surviving an Earthquake
1) Most everyone who simply "ducks and covers" when building collapse is crushed to death. People who get under objects — like desks or cars — are crushed.
2) Cats, dogs, and babies often naturally curl up in the fetal position. You should too in an earthquake. It is a natural safety/survival instinct. You can survive in a smaller void. Get next to an object, next to a sofa, next to a bed, next to a large bulky object that will compress slightly but leave a void next to it.
3) Wooden buildings are the safest type of construction to be in during an earthquake. Wood is flexible and moves with the force of the earthquake. If the wooden building does collapse, large survival voids are created. Also, the wooden building has less concentrated, crushing weight. Brick buildings will break into individual bricks. Bricks will cause many injuries but less squashed bodies than concrete slabs.
4) If you are in bed during the night and an earthquake occurs, simply roll off the bed. A safe void will exist around the bed. Hotels could achieve a much greater survival rate in earthquakes simply by posting a sign on the back of the door of every room telling occupants to lie down on the floor, next to the bottom of the bed during an earthquake.
5) If an earthquake happens and you cannot easily escape by getting out the door or window, then lie down and curl up in the fetal position next to a sofa or large chair.
6) Most everyone who gets under a doorway when buildings collapse is killed. How? If you stand under a doorway and the doorjamb falls forward or backward you will be crushed by the ceiling above. If the doorjamb falls sideways you will be cut in half by the doorway. In either case, you will be killed.
7) Never go to the stairs. The stairs have a different "moment of frequency" (they swing separately from the main part of the building). The stairs and remainder of the building continuously bump into each other until structural failure of the stairs takes place. The people who get on stairs before they fail are chopped up by the stair treads — horribly mutilated. Even if the building doesn't collapse, stay away from the stairs. The stairs are a likely part of the building to be damaged. Even if the stairs are not collapsed by the earthquake, they may collapse later when overloaded by fleeing people. They should always be checked for safety, even when the rest of the building is not damaged.
8) Get near the outer walls of buildings or outside of them if possible — it is much better to be near the outside of a building than the interior. The farther inside you are from the outside perimeter of the building, the greater the probability that your escape route will be blocked.
9) People inside of their vehicles are crushed when the road above falls in an earthquake and crushes their vehicles [picture above], which is exactly what happened with the slabs between the decks of the Nimitz Freeway. The victims of the San Francisco earthquake all stayed inside of their vehicles. They were all killed. They could have easily survived by getting out and sitting or lying next to their vehicles. Everyone killed would have survived if they had been able to get out of their cars and sit or lie next to them. All the crushed cars had voids 3 feet high next to them, except for the cars that had columns fall directly across them.
10) I discovered, while crawling inside of collapsed newspaper offices and other offices with a lot of paper, that paper does not compact. Large voids are found surrounding stacks of paper.

Listed below are links to weblogs that reference Experts' Expert: Where to go during an earthquake (if you want to survive):
When I lived in the San Francisco Bay area, I worked in a one-story "slab" building (made of precast concrete slabs that are stood on end and framed with a roof etc.). We'd get substantial earthquakes and while everyone else hid quivering under their desks or in doorways I walked through a fire exit and stood about 50 feet away from the building outside. People were astonished - "why do that? You should stay in a doorway or under a desk!!". I explained that a 25' tall building isn't likely to fall 50 feet sideways and there was nothing taller to fall on me. I had a lot of company during quakes after that.

The excellent Equipped to Survive site discusses Copp's advice in a very reasoned manner: http://forums.equipped.org/ubbthreads.php?ubb=showflat&Number=194781 Summary: You probably won't have enough time to assess which way to go.
But are you willing to listen to a guy who lied to the 9/11 Special Compensation Fund? http://www.abqjournal.com/terror/196540nm07-11-04.htm
