Tsunami safety: what to do
A tsunami can reach the coast minutes after a large undersea earthquake. Strong or long shaking near the sea is a warning in itself.
What to do
- Move inland or to high ground immediately, at least 30 m (100 ft) above sea level if you can.
- Go on foot if roads are jammed. Do not go to the shore to watch.
- Stay away until officials say it is safe. Waves can keep coming for many hours.
