Federal, state, and local emergency management experts and other official preparedness organizations all agree that "Drop, Cover, and Hold On" is the appropriate action to reduce injury and death during earthquakes.

With its fair share of earthquakes California agencies are participating in drills on Thursday. The 'Great ShakeOut' day is for schools, companies and agencies to take a serious approach to earthquakes by having drills. The drills are designed much like tornado or fire drills to educate employees, students and others on what to do should an earthquake hit your area.

The ShakeOut is our opportunity to practice how to protect ourselves during earthquakes.

Organizers say 10.2 million people are registered to take part in the "Great California ShakeOut" at 10:19 a.m. Thursday.

Participants include more than 6 million K-12 students and nearly 2 million people at colleges and universities as well as governments, businesses, faith-based organizations and individuals.

An additional 42 million people have registered for other ShakeOut drills across the United States and its territories as well as in British Columbia to Japan, Italy and New Zealand.

The ShakeOut drills originated in California in 2008.
