Note: The National Oceanographic and Atmospheric Association (NOAA), marine radio and local radio, television stations, and outdoor sirens will broadcast official warnings when a tsunami is possible. Sign up for NOAA text and phone alerts to stay informed.
PREPARING BEFORE A TSUNAMI
Being prepared can help increase your chances of staying safe during a tsunami.
- Identify safe evacuation routes in your area. Know where to find higher ground and how to reach designated evacuation sites. Familiarize yourself with the local emergency management plan and adhere to the instructions provided by authorities.
- Create a family emergency plan. Designate a safe meeting place, establish a communication plan, and assign responsibilities to each family member. Ensure everyone knows the evacuation routes and how to stay safe.
- Assemble a disaster supply kit. Include non-perishable food, water, a first aid kit, batteries, flashlights, a battery-powered radio, and essential medicines. Regularly check and update your supply kit to ensure everything is functional and not expired.
- Consider buying flood insurance. Tsunamis can lead to catastrophic property damage, and most standard homeowners policies do not cover damage caused by floods. If you live in a coastal area, talk to your local independent agent about protecting your protecting your property with flood insurance.
WHAT TO DO DURING A TSUNAMI
Act quickly and follow official guidelines if you receive a tsunami warning or expect one may be possible.
- Regularly check local news or radio for updates. If an official warning is issued, follow the instructions provided by authorities, including evacuation orders.
- Evacuate. Leave coastal areas immediately if an evacuation order is issued. Remember to grab your emergency kit and vital documents before you go.
- Shelter in place. If evacuation is not possible, seek higher ground or move to the upper floors of a sturdy building. Avoid windows—they could shatter under wind, rain, and water strain.
- Safety precautions for boating. Head to deeper waters if you are out at sea or boating near the coast when a tsunami warning is issued. Avoid harbors, rivers, and estuaries, as they can become hazardous during a tsunami.
STAYING SAFE AFTER A TSUNAMI
Continue to take precautions and follow guidance from local authorities on areas to avoid and places to take shelter.
- Stay tuned for emergency alerts. Earthquake aftershocks could generate another tsunami.
- Return home only after local officials confirm it is safe.
- Be aware of electrocution risks. Do not touch electrical equipment if it is wet or standing in water, and avoid downed power lines.
- Stay away from damaged structures, including buildings, roads, and bridges.
- Be aware of fire risks. Do not light matches or turn on lights or appliances until it’s confirmed there are no gas leaks or flammable liquids nearby.
- Don’t drink contaminated water. Tsunamis can contaminate water supplies. If available, drink bottled water until local authorities confirm tap water is safe to consume.
- Document any property damage. Take pictures of damaged property when authorities confirm it is safe. Contact your independent agent or insurance company for assistance.
Tsunamis can be unpredictable, so staying informed is crucial. Remain calm and take immediate action when necessary.
