The Great California ShakeOut: How to Participate:
- Drop, cover and hold on. On Thursday, Oct. 21 at 10:21 a.m., the website suggests drill participants to drop the ground, take cover under a table or desk and hold on as if a major earthquake were happening. It is important to practice now so you can immediately protect yourself during earthquakes. The website features an information page on what to do if you are in bed, outside, driving or in a tall building when an earthquake hits.
- Use your imagination. While you are participating in the drill, wherever you are, look around and imagine what would happen if a major earthquake were occurring. What would fall on you or others? What would be damaged?
- Text first, talk second. Once the "earthquake" has ended, send text messages to your friends and loved ones to make sure they're alright. The website suggests texting before calling, as texting enables you to send a mass text message and reach more people in a shorter amount of time.
