THE ESSENTIAL ACTION
A strong or long earthquake, sudden ocean change, or loud ocean roar can be a natural warning. Move inland or uphill without waiting for an official alert.
Before: make the plan
- Study the local tsunami evacuation map. Walk your route and account for mobility needs.
- Know more than one way to reach safe ground. Keep a small bag ready to carry.
- Learn how local alerts are delivered and what the signs on your beach mean.
During: protect people
- After earthquake shaking stops, leave the coast immediately if you detect natural warning signs.
- Follow evacuation instructions. Do not go to the shore to watch or photograph waves.
- Stay away from harbours, estuaries, and waterways connected to the sea.
After: recover carefully
- Remain in a safe area until officials give the all-clear. More waves and strong currents can follow.
- Do not assume that a quiet sea or the first wave passing means the threat has ended.
