International ShakeOut Day

International ShakeOut Day, observed on October 16, is a worldwide earthquake-preparedness observance that encourages people to learn what to do before, during, and after an earthquake. It reminds individuals, families, schools, workplaces, and communities that a few minutes of preparation can make a meaningful difference when the ground begins to shake.

A central part of the observance is practicing the recommended response: **Drop, Cover, and Hold On**. Participants may also review emergency plans, secure heavy items, prepare supplies, and discuss communication steps with loved ones. International ShakeOut Day turns earthquake safety into a shared, practical activity—helping communities feel more informed, confident, and ready to protect one another.

International ShakeOut Day is a public earthquake-preparedness observance held on October 16. Its central message is the safety procedure “Drop, Cover, and Hold On”: people are encouraged to drop to the ground, take cover beneath a sturdy table or desk, and hold on until the shaking stops. The observance treats earthquake readiness as a practical skill that should be rehearsed before an emergency rather than improvised during one.

The event originated in the United States after earthquake scientists, emergency managers, government agencies, and community organizations developed the Great Southern California ShakeOut in 2008. The exercise was designed to test how millions of people might respond to a major earthquake and to draw attention to preparedness measures such as securing heavy objects, creating emergency plans, and assembling supplies. Its large-scale format demonstrated that an earthquake drill could involve entire communities rather than being limited to schools, workplaces, or emergency services.

Over time, the ShakeOut model expanded beyond Southern California and became an international campaign. Schools, businesses, public institutions, families, and governments in earthquake-prone regions began organizing drills and educational activities under the ShakeOut name. The observance evolved from a regional preparedness exercise into a broader public-awareness movement, using registration campaigns, instructional materials, and coordinated practice to encourage people to make earthquake safety part of their regular emergency planning.

The cultural significance of International ShakeOut Day lies in its emphasis on shared responsibility and collective readiness. Earthquakes can occur with little warning, so repeated practice helps replace panic with familiar actions and encourages communities to consider the needs of children, older adults, people with disabilities, and others who may require additional assistance. Observed on October 16, the day also reinforces the idea that disaster preparedness is not only the work of emergency professionals; it is a civic habit that individuals and communities can develop together.
