Nearly 10 million businesses, schools, organizations and neighborhoods will participate in the largest earthquake drill ever.
On November 20, the Great California ShakeOut will take place at 10:20 a.m. The annual event offers individuals an opportunity to learn and prepare for the next earthquake.
"The best way to instinctively and immediately do the right thing when the shaking begins is to practice," according to Mark Benthien, Communications Director of the Southern California Earthquake Center at the University of Southern California.
The shakeout.org website includes guidelines for what to do before, during and after an earthquake. The goal the organizers say is to make sure everyone has a plan.
The organizers of the event include several government organizations like the U.S.G.S. and other organizations like the American Red Cross.
