Natural hazards
Tsunami
Natural warning signs and what to do immediately.
- Natural warnings: a long or strong earthquake, a sudden rise or fall in sea level, or loud and unusual noises from the sea. If you notice any of these, move immediately.
- Go to the nearest high ground or as far inland as you can. If evacuation maps are available, follow them.
- Walk, run or cycle if you can, to avoid traffic.
- Stay away from the coast until officials tell you it is safe. A tsunami can be a series of waves.
- Official warnings may come through Emergency Mobile Alert, radio, and Civil Defence.
