Last November, California took part in the largest earthquake preparedness drill in U.S. history. Called the Great California ShakeOut, it was based on the notion of a magnitude 7.8 earthquake, one that originates at the Salton Sea on the San Andreas Fault and rupturing northward 190 miles. Participating experts (and there were many) estimated that such a quake would kill 1,800 people, injure 50,000, and cause $200 billion in damage.
