When a tsunami warning is issued, there may be little time to make important decisions. The best way to protect yourself and your family is to prepare before an emergency occurs.

Whether you live near the coast or regularly travel to coastal destinations — including guides to coastal preparedness — having a simple preparedness plan can help reduce stress and improve safety during a tsunami event. This checklist covers the key steps every household should consider.

Why Preparedness Matters

Tsunamis can arrive with little warning, especially following nearby earthquakes. Preparedness helps you respond more quickly, reduce confusion during emergencies, communicate with family members, access important supplies, and follow evacuation plans confidently.

Preparation does not need to be complicated. Small steps taken today can make a significant difference when it matters most.

Understand Your Local Risk

The first step is understanding whether you live, work, or travel in a tsunami-prone area. Research your local tsunami hazard maps, evacuation zones, designated evacuation routes, and nearby high ground locations. Many coastal communities provide this information through local emergency management agencies — it is worth finding out before you ever need it.

Find Your Hazard Zone

Search for your local or regional emergency management agency online. Most coastal authorities publish official tsunami hazard maps and evacuation zone information that is free to access.

Know Your Evacuation Route

Every household should know where to go, how to get there, the alternative routes available, and roughly how long evacuation may take. Practice your evacuation route occasionally so it becomes familiar — ideally with all household members.

If possible, identify multiple evacuation options in case roads become blocked or congested during an event.

Prepare an Emergency Kit

A basic emergency kit should be easy to access and ready to take if evacuation becomes necessary. Key items to include:

  • Water — at least several days' supply where practical
  • Non-perishable food — items that require no refrigeration
  • Flashlight — with spare batteries
  • Portable phone charger — a fully charged power bank
  • First aid supplies — basic medical and first-aid items
  • Important documents — copies of ID, insurance, and emergency contacts
  • Medications — an adequate supply of essential medications

Create a Family Communication Plan

Families may become separated during emergencies. See our detailed guide on creating a family communication plan. Discuss emergency meeting points, contact numbers, an out-of-area contact who can relay messages, and communication methods if phone networks become overloaded.

Children should know who to contact and where to go if family members become separated. A written plan — even a simple card — can be invaluable when stress is high and thinking clearly is difficult.

Stay Informed

Access to reliable information is critical during emergencies. Monitor local emergency management agencies, official warning centres, emergency broadcasts, and trusted alerting services.

Receiving alerts directly on your mobile device can help you stay informed as conditions change — often faster than broadcast media or word of mouth.

Real-Time Alerts with Tsunami Shield

Learn Natural Warning Signs

Not all tsunamis arrive after an official warning — particularly when the source earthquake is very close to shore. Natural warning signs to know include:

**Strong coastal earthquake** — If the ground shakes strongly near the coast, move to higher ground immediately without waiting for an official warning.

**Sudden ocean retreat** — Rapid withdrawal of water from the shoreline can indicate an approaching tsunami wave.

**Unusual ocean behaviour** — Unexpected currents, surges, or sudden changes in water levels should be treated seriously.

If you observe any of these signs, do not wait for official confirmation before seeking safety.

Consider Pets and Vulnerable Family Members

Emergency planning should include pets, elderly relatives, young children, and individuals with mobility challenges. Consider transportation requirements and any additional supplies that may be needed for each person — and practice evacuation with all household members so everyone knows the plan.

Review Insurance and Important Records

Preparedness also includes protecting important information. Store insurance records, property information, identification documents, and emergency contacts somewhere accessible. Consider secure digital backups where appropriate — cloud storage or a password-protected app can provide a reliable second copy.

If You Travel Frequently

Travellers visiting coastal destinations should take the same approach as residents — read our guide on traveling with Tsunami Shield: understand local tsunami risks, identify evacuation routes, know where higher ground is located, and install trusted alerting tools before departure. Preparation is just as important while travelling as it is at home.

Set Up Travel Mode Before You Fly

In Tsunami Shield, add your destination countries to Travel Mode before you board. The app will then monitor those regions and notify you of any tsunami or earthquake alerts — even if you are not yet familiar with local warning systems.

Annual Preparedness Review

Preparedness is not a one-time activity. Set aside time each year to update emergency contacts, replace expired supplies in your kit, review evacuation routes for any changes, and discuss the plan with all family members. Small updates help keep plans effective as circumstances change.

How Tsunami Shield Supports Preparedness

Tsunami Shield helps users stay informed through official tsunami alerts, earthquake monitoring, saved locations, regional monitoring, and emergency assistance features. Preparedness starts with awareness — and timely, reliable information can support more confident decisions during coastal emergencies.

Your Tsunami Preparedness Checklist

Use this checklist as a starting point and adapt it to your household's specific needs:

  • Research your local tsunami hazard zone and evacuation routes
  • Identify your nearest high ground and multiple exit routes
  • Practice your evacuation route with all household members
  • Prepare and store an emergency kit in an accessible location
  • Create a family communication plan with meeting points
  • Identify an out-of-area emergency contact
  • Install a trusted tsunami alerting app and set up your key locations
  • Learn the natural warning signs of a tsunami
  • Include pets and vulnerable family members in your plan
  • Store digital and physical copies of important documents
  • Review and update your plan annually

Final Thoughts

Preparedness is one of the most effective ways to reduce risk during a tsunami emergency. By understanding local hazards, preparing emergency supplies, planning evacuation routes, and staying informed, individuals and families can respond more confidently when warnings occur.

You do not need to do everything at once. Start with a few simple steps and build your preparedness plan over time — every step forward matters.
