Strong earthquake near the coast, unusual ocean behavior (rapid rise or drain of water), loud roaring sound from the ocean. If you notice any of these, don't wait for an official warning - move to high ground immediately.
🗺️ Know Your Evacuation Route
Plan a route to ground at least 100 feet above sea level or 2 miles inland. Practice walking the route so you can do it quickly. If you can see the wave, you are too close to escape.
During a Tsunami
✓ Do
Move inland or to high ground NOW
Go to 3rd floor or higher if trapped
Stay away until official all-clear
Grab onto something floating if caught
✗ Don't
Go to the beach to watch waves
Wait for official warning after quake
Return after the first wave
Stay in low-lying coastal areas
🌊 Multiple Waves
Tsunamis arrive as a series of waves that can continue for hours. The first wave is often NOT the largest. Stay away from the coast until authorities give the official all-clear, which may take many hours.
🏢 Vertical Evacuation
If you cannot reach high ground, go to the upper floors (3rd floor or higher) of a sturdy concrete building. Move as far from the ocean-facing side as possible. This is a last resort - always try to move inland first.
After a Tsunami
✓ Do
Wait for official all-clear signal
Avoid disaster areas if possible
Check yourself and others for injuries
Listen to authorities for instructions
✗ Don't
Return home until declared safe
Drink tap water until tested
Enter damaged buildings
Touch downed power lines
🏚️ Returning Home
Wait for authorities to declare the area safe. Watch for debris, damaged roads, and weakened bridges. Check your home for structural damage before entering. Be alert for gas leaks - if you smell gas, leave immediately and call authorities.
🧹 Cleanup Hazards
Tsunami debris may contain hazardous materials, sewage, and sharp objects. Wear protective clothing, gloves, and sturdy boots. Take photos of all damage for insurance claims before cleaning up.
