Last week, San Francisco joined millions of people around the world for the Great ShakeOut, an annual earthquake preparedness drill that encourages individuals, schools, businesses, and communities to practice how to stay safe during an earthquake. We gathered at Grattan Elementary School alongside Mayor Daniel Lurie, San Francisco Fire Chief Dean Crispen, DEM Executive Director Mary Ellen Carroll, and SFUSD Superintendent Dr. Maria Su to highlight the importance of earthquake preparedness and practicing lifesaving safety actions. When an earthquake strikes, remember to Drop, Cover, and Hold On: •DROP to your hands and knees to prevent being knocked over. •COVER your head and neck, and get under a sturdy table or desk if possible. •HOLD ON to your shelter and stay in place until the shaking stops. Preparedness doesn't end with a drill! Learn about other ways to prepare at sf.gov/earthquake
