While some areas of California are more likely to have earthquakes than others (see below), all of California is at higher risk compared to the rest of the country. You could be anywhere when an earthquake strikes: at home, at work, at school, or even on vacation.
The Great California ShakeOut is an annual opportunity to practice how to be safer during big earthquakes: "Drop, Cover and Hold On." 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.
