Near the coast? Know your tsunami plan

If you are near the coast and feel an earthquake that is long or strong, don't wait for someone else to advise you – you need to get gone, says Auckland Civil Defence and Emergency Management.

A tsunami is a series of waves caused by large earthquakes. A tsunami wave can grow to become a fast-moving wall of water.

Natural warning signs of a tsunami

  1. A strong earthquake that makes it hard to stand up, or a weak rolling earthquake that lasts a minute or more
  2. A sudden rise or fall in sea level
  3. Loud and unusual noises from the sea.

If you are at the coast and experience any of these warning signs, move immediately to the nearest high ground, or as far inland as you can. Walk or bike if possible.

Do not wait for official warnings.

A local-source tsunami could arrive in minutes, meaning there wouldn't be time for an official warning. It is important to recognise the natural warning signs and act quickly.

Remember: Long or strong – GET GONE
