A tsunami is a series of fast-moving waves produced by a submarine earthquake, subsidence or volcanic eruption.
As a tsunami crosses a deep ocean the length from crest to crest may be as much as 150 kilometres and the waves can travel at speeds of 1,000km/h.
Because of the limited warning time for a tsunami, it is important for you to plan and be prepared in advance.
What can you do to prepare?
- Familiarise yourself with information about tsunamis and the natural warning signs.
- Visit the Bureau of Meteorology website for more details.
- Develop an Evacuation Plan for your household.
- Make sure your Emergency Kit is current and easily accessible.
How will you be advised of a potential Tsunami?
The Joint Australian Tsunami Warning Centre (JATWC) is jointly operated by the Bureau of Meteorology and Geoscience Australia.
The JATWC detects and verifies any tsunami threat to the coastline of Australia.
Warnings will be relayed through Emergency Authorities via official channels.
