Act now

If you are in immediate danger of a tsunami, seek higher ground as far inland and as quickly as possible.

  • First, protect yourself from an earthquake. Drop, Cover, then Hold On.
  • Get to high ground as far inland as possible.
    Be alert to signs of a tsunami, such as a sudden rise or draining of ocean waters.
  • Listen to emergency information and alerts.
  • Evacuate: DO NOT wait! Leave as soon as you see any natural signs of a tsunami or receive an official tsunami warning.
  • If you are in a boat, go out to sea.
