Six Safety Tips on How to Survive a Tsunami

Tsunamis are a powerful natural force demonstrating the earth’s raw and unpredictable strength. These monstrous waves, unleashed by seismic disturbances beneath the ocean’s surface, can race across the water at incredible speeds, causing catastrophic damage to structures and landscapes. 

While the occurrence of a tsunami is beyond human control, our preparedness and response to such a catastrophe are not. This article aims to provide you with critical safety recommendations for surviving a tsunami, empowering you with the knowledge that could make the difference between life and death.

How to Survive a Tsunami

1. Have an Evacuation Plan

In the event of a tsunami, having a well-prepared evacuation tactic can be key. These tactics should include the quickest path to a safe, elevated location from prominent locations such as your home, workplace, or school. 

All members of your family should understand this process. Regular exercises help ensure everyone understands what to do in an emergency, facilitating a quick and effective evacuation.

The plan should also consider other scenarios, such as obstructed routes, and recommend alternatives. If separation occurs, establish a safe meeting spot. 

Additionally, have a communication mechanism in place to call out to one another and assure your safety.

2. Learn about Tsunami

Learning about tsunamis is vital for coastal areas to keep prepared and safe. With the growth of technology, education is now widely accessible through various resources, including videos and even higher education programs like an Online Masters of Homeland Security.

These resources contain in-depth information about home security, safety precautions, leadership, and policymaking skills to reduce their impact. Enrolling in such online programs enables individuals to obtain skills in disaster management, emergency response, and risk assessment, enabling them to protect their communities effectively.

3. Understand the signs 

Understanding tsunami warning indicators may drastically enhance your odds of survival. There are two types of warning signs: natural and official.

Natural Warning Signs: These are nature’s own alerts that a tsunami is on the way. Below are a few warning signs:

  • Earthquakes: Because tsunamis are frequently produced by undersea earthquakes, sensing an earthquake could be your first warning. If you live near the coast and witness a significant earthquake, this could be a harbinger of a possible tsunami.
  • Sea-level Withdrawal: Another powerful natural indicator of a near tsunami is the rapid withdrawal of the sea, exposing the ocean floor. This strange water behavior could indicate that a tsunami wave is gaining strength offshore.
  • Unusual ocean Sounds: People frequently describe a deafening roar, comparable to that of a train or airplane, before the arrival of a tsunami. If you hear this near the coast, especially after an earthquake or sea withdrawal, it’s best to assume a tsunami is coming.

Official Warn Signs:

Official warning signals are issued by municipal, national, or international institutions that monitor earthquake activity and ocean behavior. These organizations harness gadgets to identify earthquakes and ocean disturbances that might generate tsunamis. They then issue notifications to advise people in potentially affected areas.

  • Tsunami Warnings: These are the most serious notifications, suggesting that a tsunami is impending. They will frequently indicate the expected arrival time and the regions that must be evacuated immediately.
  • Tsunami advisories: are issued when a tsunami is possible, but the amount of hazard is unknown. People in these locations should remain vigilant and ready to move if required.
  • Tsunami Watches: These are preliminary warnings indicating that an earthquake has occurred, perhaps resulting in a tsunami. A watch is a call for people to be alert to further updates.

These warning indicators are often delivered via SMS, emails, TV and radio broadcasts, outdoor sirens, and other communication channels.

4. Move to Higher Ground

When a tsunami warning is issued, evacuating promptly and seeking higher ground is vital. Because tsunamis are powerful and rapid and may sweep away areas. Therefore, elevation and distance from the coast are your best defenses.

Elevation acts as a basic yet efficient tsunami barrier. Aim for a place at least 100 feet above sea level. This altitude is generally considered safe from even large tsunamis. If you cannot properly estimate altitude, your goal should be to reach as high as possible because every foot of elevation reduces your danger.

If you’re in a flat area and can’t get to higher ground, distance should be your priority. Strive to travel at least two miles inland from the beach. Tsunamis can reach a long distance inland, particularly in coastal locations with bays, inlets, or rivers. As a result, traveling as far inland as feasible is critical.

If these locations are beyond reach, or if time is short, look for a substantial, multi-story building nearby. Go to the highest possible floor or even onto the roof if it’s safe. 

In some areas, specially designated tsunami vertical evacuation buildings are developed to provide safe, high ground where the natural high ground does not exist.

5. Stay away from the shore

If a tsunami warning has been issued, resist the urge to stay and watch the waves or snap photographs. It’s a normal human instinct to be drawn to the extraordinary and visually magnificent, and a tsunami certainly meets this definition. 

However, it’s crucial to remember that tsunamis are dangerously powerful natural phenomena, not sights to be witnessed up close.

Often, the first wave of a tsunami is not the most powerful. The subsequent waves, which could arrive minutes or even hours later, could be substantially larger and more damaging. 

Even if the initial wave appears tiny, don’t think staying near the coast or returning if you’ve already evacuated is safe.

Another deceiving feature is that tsunamis are unlike regular waves; they do not crash at the water’s edge and retreat. Instead, they behave more like quickly rising waves that can surge inland for many miles, particularly in coastal locations with flat ground.

6. Prepare a Disaster Kit

A well-stocked disaster kit is crucial in the aftermath of a tsunami, providing necessary supplies when usual resources might be unavailable. It should contain sufficient bottled water and non-perishable food to last at least three days for each family member. 

Include a first-aid kit with essential medicines, bandages, antiseptics, and prescription medications. 

Other key items are a flashlight and a battery-powered or hand-crank radio for news updates. Important documents, cash, and a fully charged cellphone with backup chargers should also be included. All these items should be packed in a waterproof, easily transportable bag.


While the power of a tsunami cannot be controlled, your response can be. Preparing in advance, recognizing the signs, and acting swiftly during a tsunami can make all the difference in your survival and safety. 

Every second counts, and knowing what to do can save lives—possibly even your own.
