Are you ready for Hawaiʻi's next big earthquake?
September 22, 2017

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

We encourage you to participate in the Great Hawaii ShakeOut earthquake drill at 10:19 a.m., HST, on October 19, 2017.

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

"Earthquakes in Hawaii: What you need to know" is a slide show about Hawaii's long history of damaging earthquakes and what you can do to protect yourself and your family when the next one happens.

For more info on how to minimize the risk of injury during an earthquake, go to: "Recommended Earthquake Safety Actions in Hawaii."
