I don’t want to get involve in a long-drawn out discussion on this, since I never heard of this “Triangle of Life” thing before today, but in the interests of sharing information, here is what the American Red Cross (apparently) actually said about it (unless this is a fake):
“The Red Cross is not saying that identifying potential voids is wrong or inappropriate. What we are saying is that ‘Drop, Cover, and Hold On!’ is NOT wrong — in the United States. The American Red Cross, being a U.S.-based organization, does not extend its recommendations to apply in other countries. What works here may not work elsewhere, so there is no dispute that the “void identification method” or the “Triangle of Life” may indeed be the best thing to teach in other countries where the risk of building collapse, even in moderate earthquakes, is great.”

I guess now all we have to do is work out whether the “the risk of building collapse, even in moderate earthquakes, is great” or not…
