Great ShakeOut Earthquake Drills

Every October, millions of people worldwide practice how to Drop, Cover, and Hold On during Great ShakeOut Earthquake drills

More than 10.7 million Californians participated in the 2016 Great California ShakeOut earthquake drill and practiced how to "Drop, Cover, and Hold On." Each year's drill creates new record numbers, and the registration numbers are expected to continue to grow for 2017.
