Could “The Impossible”
happen here in Hawaii?
• Many resorts and tourists in both places.
• Similar education and evacuation challenges.
• Similar tropical climates.
• Hawaii has no subduction zone nearby. Large local
tsunamis are extremely unlikely here.
• Most large tsunamis in Hawaii come from far away and
give ample time to evacuate.
• Hawaii has a well-developed tsunami warning system.

Tsunami Safety Tips
• If you are near the beach and feel strong earthquake shaking, that is
your warning. Head to higher ground.
§ Walking mauka for 15-20 minutes or going to the 4th floor of a strong
building is usually sufficient. Do not drive!
• An unusual draining of the sea is a natural tsunami warning sign,
although this doesn’t happen in every tsunami situation.
• A tsunami is a series of waves, and the first wave may not be the
§ Since the time between waves is 5-60 minutes, the danger can last for
several hours. Be prepared with food, water, and a radio.
• Tsunami waves wrap around islands, so all coastlines are at risk.
• If a warning is issued, follow instructions.
§ Local warnings (for tsunamis generated in Hawaii) require immediate
action, but warnings from distant events are less urgent.
• If you are in a boat at sea, make sure you’re in deep water and stay
there. Bays and harbors, however, are dangerous places.
Stay safe and enjoy the beach!
