Participants who signed up received text messages, emails, automated phone calls or other notifications telling them that it was a drill and giving them an opportunity to practice earthquake safety drills.
“The Great California ShakeOut is an annual opportunity to practice how to be safer during big earthquakes: ‘Drop, Cover and Hold On,’” says the ShakeOut website, which lists the participating agencies. “The ShakeOut has also been organized to encourage you, your community, your school, or your organization to review and update emergency preparedness plans and supplies, and to secure your space in order to prevent damage and injuries. ShakeOut is also a reminder for Californians to be prepared financially, such as by exploring earthquake insurance. The not-for-profit California Earthquake Authority offers earthquake insurance throughout California for homeowners, renters, mobile home owners and condo-unit owners.”
