Start here to be included in the
2023 Great Guam ShakeOut!

This year's International ShakeOut Day is October 19, when millions of people worldwide will participate in earthquake drills at work, school, or home!

At 10:19 am (local time) on 10/19, you can join people across Guam practicing earthquake safety. While we encourage you to participate with everyone, you can register your ShakeOut drill for any day of the year, and drill at a time of your choice. You can also include people in multiple locations through video conferencing.

It's actually a good idea to practice earthquake safety in different situations each year, and ShakeOut Organizers are here to support you.
