Guam is taking part in the world’s largest earthquake drill, the Great ShakeOut, today Oct. 17, at exactly 10:17 a.m. (ChST).

Participants will practice the earthquake response procedure; “Drop, Cover and Hold On” from wherever they are. The drill will last for one minute.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) encourage all residents to increase earthquake preparedness and response by practicing how to protect themselves during an earthquake and how to ensure an earthquake disaster does not become a catastrophe.

The ShakeOut participation provides the opportunity to evaluate emergency plans, increase awareness of earthquake safety, and improve resiliency within your community.

To participate in this year’s ShakeOut, residents must register online at or call (671) 475-9600.

The ShakeOut website provides drill manuals, tips on earthquake safety and other resources for developing a disaster plan.

Residents may register as an individual, family, school, business, or other group and are encouraged to share photos of their ShakeOut experience on the Great Guam ShakeOut website.

Island residents will join over 60 million ShakeOut participants from across the world from U.S., Hawaii, British Columbia, CNMI, New Mexico, Puerto Rico, Southern Italy, and other various regions.
