How you might be warned about a Tsunami
The natural warning signs of Tsunami
In Australia you may receive an official Tsunami Warning, however it is also important to be aware of the natural warning signs:
- FEEL the earth shake. If you are near the ocean and you feel the ground shake, a strong earthquake may have occurred and possibly caused a tsunami. However, you may not feel the earth shake if the earthquake occurred long way away.
- SEE the ocean drop. Before a tsunami arrives, the ocean level may (but not always) drop dramatically before returning as a wall of water. If you notice that the water is disappearing, tell your family and friends and prepare to move to higher ground.
- HEAR an unusual roaring sound. If you hear a loud roaring sound from the ocean (a bit like an aeroplane or a train), tell your family and friends. This sound may be heard before a tsunami arrives.
