Millions of people worldwide participate in this annual earthquake and tsunami drill to build muscle memory to Drop, Cover, and Hold On at 10:17 a.m. on Oct.  17.

This is a FREE event, where you practice at home, school or work. Drop, cover and hold on for a minute, then do one more thing like build an emergency kit and talk to family about what to do after a disaster.

Feel free to take a picture of you, friends and family under a desk or table and use #ShakeOut on social media.
