Here is what to do before, during, and after a tsunami:

Before a Tsunami

• Learn the natural signs of a tsunami, such as a strong earthquake, a loud roar from the ocean, sudden rise or fall of the sea, or unusual ocean behavior

• Know your community’s tsunami evacuation zones and routes. Plan multiple evacuation routes from home, work, and other places you frequent, aiming for shelters at least 100 feet above sea level or one mile inland

• Create a family emergency communication plan with an out-of-state contact and decide on meeting places if separated

• Assemble an emergency kit with essentials like water, food, medications, flashlight, portable radio, warm clothes, and important documents

• Sign up for local warning systems and understand official tsunami alerts and warnings

• Practice tsunami evacuation drills and familiarize yourself with evacuation routes and safety zones

• Consider appropriate insurance for earthquake and flood damage, as standard homeowner’s insurance usually does not cover these

• Secure your home by learning how to turn off utilities (water, gas, electricity) and prepare for possible infrastructure outages

During a Tsunami

• If an earthquake occurs and you are in a tsunami hazard area, first protect yourself from the earthquake by dropping, covering, and holding on until shaking stops

• Immediately move to the nearest high ground or as far inland as possible after the shaking stops or if you observe natural tsunami warning signs, without waiting for official warnings

• Take your emergency kit and pets with you if it is safe to do so

• Use evacuation routes marked by tsunami signs and avoid driving unless necessary; walking or biking is preferred to keep roads clear

• If you cannot evacuate, seek refuge in an upper floor of a sturdy building, climb a tree, or grab a floating object if in water

• If in a boat, head out to deep water away from shore if time allows; otherwise, secure the boat and evacuate to higher ground

• Never go to the shore to watch the tsunami waves

After a Tsunami

• Continue listening to emergency broadcasts and do not return to evacuated areas until officials declare it safe

• Be aware that multiple waves may occur over several hours; the first wave is not always the largest

• Check yourself and others for injuries and provide first aid if trained

• Avoid floodwaters and debris, as they may be hazardous

• Inspect buildings carefully for structural damage, gas leaks, and electrical shorts before entering

• Document property damage with photos and notes for insurance claims, and contact your insurance or landlord as appropriate

• Follow official guidance on returning home and cleanup

These steps help reduce risk and improve survival chances before, during, and after a tsunami event
