Tsunami

Language:

Before

Understand what a tsunami is:

  • it is not a single wave but generally a series of waves;
  • it may be a fast-moving wall of water; and
  • sometimes the only impact of tsunami will be dangerous rips and currents.

Things you can do to prepare for the unlikely event of a tsunami include:

  • being aware of the natural warning signs, such as an earthquake, rumbling or sudden changes in the behaviour of coastal seas;
  • if you live on, or regularly visit the coast, get to know the tsunami history and the coastal flood-prone areas of your community;
  • deciding where you will go if a tsunami warning is issued for your community; and
  • inviting the SES to present an awareness and education program to your community group.
Advice before a tsunami

During

  • If you receive an official tsunami warning, you may be asked to move away from the water's edge or low-lying coastal areas and move to higher ground inland.
  • For your own safety you should follow the advice given by emergency services personnel when a tsunami warning is issued.
  • Never go the beach or stay and watch once a tsunami warning has been issued.
  • For the most up-to-date warnings visit the TasALERT website, listen to your local ABC radio or visit the Bureau of Meteorology’s website.
  • Only return to the area when emergency services advise it is safe to do so.

The authority responsible for issuing tsunami warnings to Tasmania is the Joint Australian Tsunami Centre, not the Pacific Tsunami Warning Centre. For more information about tsunami warnings in Australia go to the Bureau of Meteorology website, www.bom.gov.au/tsunami.

Advice during a tsunami

After

  • Rips and currents may affect the marine environment for a period up to 48 hours after impact.
  • Do not go to the beach or into the water until you are told it is safe to do so.
