Natural warning signs

  • Feel the ground shake near the coast: a strong earthquake may have caused a tsunami (a distant one may not be felt).
  • See the sea drop suddenly or the tide go out.
  • Hear an unusual roaring from the ocean, like a plane or train.
  • A tsunami is a series of waves; the first is often not the largest.

Any of these: tell people nearby and move to higher ground.

Marine and immediate foreshore threat

  • Get out of the water and away from the water’s edge of beaches, harbours, estuaries and rock platforms.
  • Boats in harbours, estuaries and shallow water: return to shore, secure the boat, move away from the waterfront.
  • Boats already at sea: stay offshore in deep water until advised.
  • On a patrolled beach a warning siren may sound: leave the water and the area.

Land inundation threat

  • Do all of the above, and go to higher ground at least 10 m above sea level, or at least 1 km away from beaches and the water’s edge of harbours and estuaries.
  • Can’t leave? Shelter at least 10 m up in a sturdy brick or concrete building.
  • Act on the first warning. Walk if asked to evacuate, and take your emergency kit (only what you can carry).
  • If you don’t evacuate, SES is unlikely to be able to rescue you. If trapped, find a safe spot and stay there.

Afterwards

  • Stay put until emergency services say it is safe to return. Dangerous conditions may continue; impacts can last for days.
  • Throw out food and drink (including water) that touched tsunami water. Have fresh drinking water.

Prepare

  • Know where and how to turn off electricity, gas and water. Secure loose outdoor items.
  • Plan where you would walk to and tell family and neighbours. Staying with friends outside evacuation areas is best.
  • Check your insurance. Pack your emergency kit.
