If you are ever in a tsunami situation, your priority is to get to safety fast: move immediately to higher ground or far inland, stay there until authorities say it is safe, and never go back toward the coast to “look at the waves.”

⚠️ First: Life‑or‑death basics

  • If you feel a strong or long earthquake near the coast, protect yourself from falling objects (drop, cover, hold), then as soon as shaking stops, evacuate uphill or inland without waiting for any official warning.
  • Natural warning signs of a tsunami include:
    • Strong or long ground shaking.
* Sudden, unusual **retreat of the sea** (water racing away, exposing seafloor).
* A **loud roar** from the ocean like a train or airplane.
  • If you notice any of these, RUN to higher ground immediately , even if nothing has been announced yet.

If it’s long or strong, get gone : don’t wait, don’t watch, don’t film.

Before a tsunami (preparedness)

Think of this as work you do now so you don’t have to think later.

  • Know your risk zone
    • Find out if you live, work, or vacation in a tsunami evacuation zone from local disaster management or civil defence maps.
* Identify safe places at least **30 m (100 ft) above sea level and about 3 km (2 miles) inland** if possible.
  • Plan your evacuation routes
    • Walk your route to higher ground so you know how long it takes, and have a backup route.
* Note any nearby **concrete, reinforced multi‑storey buildings** you could use to reach upper floors if open ground high enough is not nearby.
  • Prepare a grab bag
    • Pack a small backpack with: water, canned/ready‑to‑eat food, flashlight, battery radio, phone power bank, medications, copies of important documents, basic first aid, a whistle.
* Keep it where you can grab it in seconds, not minutes.
  • Home readiness
    • Learn how to quickly turn off gas and electricity in your home.
* Keep important documents in **waterproof containers** on high shelves.
* Consider insurance that covers flood/tsunami damage if available.
  • Family and children
    • Decide a family meeting point on safe high ground and who is responsible for young children or elderly relatives.
* Explain to kids, in simple terms, the rule: “If the shaking is strong or the sea acts strange, we go **up and away** right away.”

During a tsunami warning or natural signs

If you are on land near the coast

  • Act immediately
    • As soon as you get an official warning or see natural signs, move to the nearest high ground or as far inland as you can.
* Do **not** wait to confirm, do **not** go to the shore to watch or film.
  • How to evacuate
    • Walk, run, or cycle if you can; this avoids traffic jams and damaged roads.
* If you must use a car (mobility issues, long distance), drive directly out of the evacuation zone and **keep going** so others can still follow.
* Follow marked tsunami evacuation signs and official routes if they are clearly passable; if they are blocked or crowded, take the fastest safe route that gains height.
  • If no hill is available
    • Go to an upper floor or roof of a strong, reinforced concrete building , at least the 3rd floor or higher.
* As a last resort, climb a very strong tree if water is rushing in and no building or hill is reachable.
  • Stay informed
    • Keep your phone on and charged to receive alerts.
* Listen to local radio, TV, or official online channels for instructions and “all clear” messages.
  • Do not return too soon
    • A tsunami usually comes as a series of waves ; later waves can be higher than the first and may arrive for hours. Stay in a safe zone until authorities declare it safe.

If you are on a boat or at sea

  • At dock or on shore in a boat
    • If you feel a strong quake or see/hear tsunami signs, leave the boat and evacuate on foot to high ground.
  • In shallow water (less than about 50 m depth)
    • Stop fishing or operations and free your vessel from any gear or anchors that tie it to the bottom.
* If you can **reach shore, beach or dock and evacuate on foot within about 10 minutes** , that is usually best.
* If you cannot get ashore safely in time, head **directly out to deeper water (greater than about 50 m)** and away from the coast, keeping separation from other vessels.
  • In deep water already (greater than about 50 m)
    • Continue heading toward deeper open water outside harbours and channels, which is safer from destructive currents and surges.

After a tsunami

Even after the waves pass, danger remains in debris, contamination, and unstable buildings.

  • Wait for the official all clear
    • Do not return to low‑lying coastal areas until emergency officials say it is safe.
  • Help safely
    • If you are safe, assist injured or trapped people only if you can do so without risking yourself , and call emergency services.
  • Avoid hidden hazards
    • Stay out of stagnant or flood water; it can be contaminated or hide sharp debris and open manholes.
* Stay away from damaged buildings, downed power lines, unstable bridges, and landslide areas.
  • Home and hygiene
    • When allowed back, open windows and doors, and remove wet mud while it is still moist so buildings can dry.
* Throw away any food that has touched flood water; assume it is contaminated.
* Check for damage to sewer and water lines; if water quality is uncertain, treat it as unsafe until tested or cleared.
  • Emotional recovery
    • Children and adults may show fear, sleep problems, or clinginess; listen carefully, reassure them, and explain that the situation is temporary and you are working to stay safe.

Short, story‑style example

Imagine you are on holiday at a beach resort.
You feel a long, rolling earthquake that makes it hard to stand, and a few minutes later you notice the shoreline pulling far back, exposing rocks you have never seen. You grab your small backpack , shout to nearby people that a tsunami might be coming, and you all run up the marked evacuation route toward a hill behind the town, not stopping for photos or luggage. You reach a lookout higher than the rooftops and stay there for several hours, listening to emergency updates on a battery radio until officials announce the all clear, then return carefully, watching for damaged buildings and contaminated water.
