International Shakeout Day

Celebrated on 10/15/2026

Quick Fact

International ShakeOut Day started in 2008 in California, where over 5.4 million people participated in the first drill. It has since grown to involve over 60 million participants worldwide annually, making it the largest earthquake drill ever organized.

Origins and Establishment of International ShakeOut Day

International ShakeOut Day was first launched in 2008 by the Earthquake Country Alliance, a partnership of earthquake professionals, emergency managers, and community organizations in California. The initiative was inspired by the need to prepare for the anticipated 'Big One' along the San Andreas Fault. The first drill, held on November 13, 2008, involved over 5.4 million participants, setting a world record. The event was designed to promote the 'Drop, Cover, and Hold On' protocol, which is recommended by experts to protect lives during earthquakes.

Evolution and Modern Commemoration

Since its inception, International ShakeOut Day has expanded globally, with countries like Japan, New Zealand, and Italy adopting the drill. In 2010, the event became international, with participation from over 10 million people outside the United States. Today, it is held annually on the third Thursday of October, with over 60 million participants from more than 60 countries. The event has evolved to include workplace, school, and community drills, and many organizations incorporate additional preparedness activities such as checking emergency kits and updating communication plans.
