Natural Warning Signs
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.
