Tsunami Preparation

Go to community meetings and discuss what to do if a tsunami is coming. Do not go near the ocean. Instead, find the highest elevated ground possible. If you are in a boat near the coast, sail out to sea if you hear a tsunami warning.
If you are in a boat or at sea, stay in the ocean, away from shore that may be one of the safest places to be.
  • Prepare an evacuation route and know it well.
  • Keep listening for tsunami warnings and further updates or instructions on the radio.
  • Get to higher ground and wait for further instructions.
*Stock up on necessary food, water, and emergency supplies for safety
  • Evacuate if necessary.
  • Wait for a signal before returning home.

Tsunami Watches and Warnings for Australia

The Joint Australian Tsunami Warning Centre (JATWC), jointly operated 24 hours a day by the Bureau and GA detects, monitors, verifies and warns of any tsunami threat to the coastline of Australia and its offshore territories.
The first stage of the tsunami warning process is a 'tsunami watch' phase, where seismologists have determined that there is the potential for an identified undersea earthquake to cause a tsunami threat to Australia. If there is a threat, the Bureau would issue a National Tsunami Watch. If there is no threat, a National Tsunami No Threat Bulletin would be issued.
The National Tsunami Watch may be reissued if a tsunami remains unconfirmed by sea level observations and any potential first point of impact on Australia is more than 90 minutes away (the minimum time criteria for warning).
If sea level observations and further data confirm the tsunami threat, or if any potential first point of impact is less than 90 minutes away, the Bureau, on behalf of the JATWC, will use its severe weather communication infrastructure to issue Tsunami Warnings for the States and Territories under threat. The Bureau's Regional Forecasting Centres (RFCs) in capital cities are the main liaison point for emergency services during tsunami events.
Once separate tsunami watches or warnings are being issued for individual States and Territories, a National Tsunami Warning Summary will also be issued listing all the watches, warnings and cancellations that are in effect for the current tsunami event. The JATWC website www.bom.gov.au will provide a complementary coastal threat graphic showing the regions currently under threat.
