"...The American Red Cross has not recommended use of a doorway for earthquake protection for more than a decade. The problem is that many doorways are not built into the structural integrity of a building, and may not offer protection. Also, simply put, doorways are not suitable for more than one person at a time."
They do recommend "Drop, cover, and hold on to something." They also admit that the "triangle of life" is a valid strategy, just not the only one.
I'll vote for that.
Anyone else?
