Are you ready for Hawaii's next big earthquake?

Earthquakes in Hawaii graphic The probability of a destructive magnitude-6.5 or higher earthquake striking the Hawaiian Islands in the next 10 years is 50 percent. Are you ready for it?

"Earthquakes in Hawaii: What you need to know" provides an overview of Hawaii's long history of damaging earthquakes and what you can do to protect yourself and your family when the next one happens.

We encourage you to participate in the
Great Hawaii ShakeOut earthquake drill
at 10:17 a.m., HST, on October 17, 2013.

This drill is a great opportunity to practice
"Drop! Cover! Hold on!"—actions that will
reduce injury during Hawaiʻi's next earthquake.
