The safest place during a tsunami is an area at least 100 feet above sea level or two miles inland, away from the coast. If reaching this elevation or distance isn't possible, go as high as you can.
Understanding Tsunami Safety
When a tsunami strikes, the most important factor in survival is distance from the coastline and/or elevation above sea level. The further you are from the water and the higher you are, the safer you will be.
Key Safety Measures:
- Evacuate Immediately: When a tsunami warning is issued, don't hesitate. Evacuate to higher ground as quickly as possible.
- Head Inland or Upward: Aim for a location at least two miles inland or 100 feet above sea level.
- Every Foot Matters: If you can't reach the recommended distance or elevation, every foot you gain inland or upward can increase your chances of survival. Even climbing to the upper floors of a strong, multi-story building can offer some protection.
- Stay Informed: Monitor official alerts and information from local authorities through radio, television, or mobile devices.
Why Height and Distance Matter
Tsunamis are powerful surges of water that can inundate coastal areas. The further inland and the higher above sea level you are, the less likely you are to be impacted by the force of the wave and the resulting flooding. The destructive power of a tsunami diminishes with distance and elevation.
What if You Can't Evacuate Far Enough?
If you cannot reach high ground or move far inland, seek refuge in a sturdy, multi-story building. Go to the highest level possible. While not ideal, this is a better option than remaining at ground level.
Before a Tsunami
- Know your location: If you are near a coast, know the evacuation routes and high ground.
- Have a plan: Discuss and practice a family emergency plan.
- Listen to authorities: Heed warnings and advisories.
