To stay safe during a tsunami, the most crucial action is to get to higher ground or move inland immediately if you sense any natural tsunami warning signs, such as a rapid sea water recession or a strong earthquake near the coast. Do not wait for official warnings. If higher ground is not accessible, head to the upper floors of a concrete and reinforced building. Avoid going to the shore to watch the tsunami. Follow official guidance and stay away from danger zones until an "all clear" is issued, as tsunamis often come in multiple waves that can last for hours. Preparing ahead is essential:
- Have emergency equipment and supplies such as flashlights, radios, first-aid kits, canned food, clean water, and medicine ready.
- Prepare and practice an evacuation plan with family members and know your local evacuation routes.
- Keep important documents in waterproof containers and learn how to turn off gas and electricity at home.
- Stay informed via weather radios or local alerts.
After a tsunami, only return when authorities say it is safe, avoid downed power lines and damaged buildings, and help injured people if possible. In summary:
- Move quickly to higher ground or inland, at least 30 meters above sea level or 3 km inland if possible.
- Recognize natural tsunami signs and do not wait for official alerts.
- Have a plan and emergency kit ready.
- Follow evacuation routes and official instructions.
- Stay away from the coast until official confirmation of safety.
