A tsunami is a deep ocean wave usually caused by large scale disturbances of the ocean such as:

  • Earthquake
  • Landslide
  • Volcanic Eruption
  • Meteorite Strike

You can learn more by visiting the Bureau of Meteorology's Tsunami web page.

The Victorian Coast’s greatest tsunami risks are from an earthquake off the coast of New Zealand or a landslide on Australia’s continental shelf in the Tasman Sea.  Tsunami can reach several kilometres inland if the topography is flat and not very high above sea level and the tsunami wave is large. 

The Australian Tsunami Warning System has been established by the Federal Government to warn Australians of approaching tsunami.  It is linked to the Pacific Tsunami System which detects tsunami generating events and tsunami in the Pacific.
