On July 29th, a powerful earthquake struck beneath the Pacific Ocean. Then tsunami alerts were issued for coastal areas in Japan, Russia, Hawaii, and elsewhere across the Pacific, going as far as parts of the United States Western seaboard . For those who live near the water, it was a terrifying but maybe familiar moment. Some grabbed their bags and ran for higher ground. Others waited, not super sure what to do. The warnings eventually lifted in some areas, but the danger and the message stays regardless.
If you live anywhere near the Pacific Ring of Fire, being prepared for natural disasters like tsunamis and earthquakes is not just a good idea. It's a necessity.
Tsunamis are not like hurricanes or wildfires. They do not just give you days of warning. They don't arrive slowly. They are sudden, powerful, and sometimes devastating. That is why preparing in advance is the best defense.
This is about responsibility, awareness, and survival. It is a guide for people who live in coastal communities or at the very least plan to travel to them, on what they can do to stay ready. Because when the next wave comes, you never know how much time you'll have to pack a bag or make a plan.
What Is a Tsunami and Why Are They So Dangerous?
A tsunami is a series of powerful waves caused by an underwater disturbance — usually an earthquake, but sometimes a volcanic eruption, underwater landslide, or even a meteorite strike. But it's important to know that not all tsunamis are 100+ feet tall like in the movies, more likely than not they'll be between 5-15 feet tall but don't think that means they're harmless. When these events displace a large amount of water, that energy travels outward in all directions at high speeds. In deep ocean water, a tsunami may only rise a few feet high, but it can travel faster than a jet airplane. When it reaches shallower coastal waters, it slows down and rises dramatically in height, slamming into shorelines with tremendous force.
These waves can easily destroy buildings, sweep away roads, knock out power grids, and more. But what makes tsunamis especially dangerous is how quickly they happen. In many cases, there is only a small window between the triggering earthquake and the wave's arrival, sometimes hours or sometimes just ten or fifteen minutes.
That means unless you are already prepared, your chances of acting in time are hard.
Why the Pacific Ring of Fire Matters
The Pacific Ring of Fire is a massive belt of seismic and volcanic activity that stretches from the western coasts of North and South America across to Japan, Southeast Asia, and the islands of the South Pacific. This region is where several of the Earth's tectonic plates meet and grind against each other, making it the most earthquake-prone zone in the world (also where the majority of volcanoes are.)
Japan, Indonesia, Chile, Alaska, and the U.S. West Coast have all experienced major tsunamis in modern history. If you live on or near any part of this ring, whether it is a beachfront home in Hawaii, a coastal town in California, or a city like Sendai in Japan, the risk is unfortunately real. And not just once every 100 years, tsunamis have struck multiple times within a generation.
If You Live on the Coast, Have a Plan
Let’s say you live in a seaside town. Maybe it is your permanent home or maybe just a weekend beach cottage. Either way, ask yourself right now: If a tsunami alert was issued in the next fifteen minutes, would you know what to do?
If the answer is no, it is time to change that. Living on or near the coast requires a serious commitment to readiness. Here are essential steps everyone should take.
1. Know the Warning Signs
Even before an official alert goes out, there are signs that a tsunami may be coming. Learn to recognize them.
-
A strong or long-lasting earthquake felt near the coast. Even if it lasts just 20 seconds, it could trigger a tsunami.
-
The sudden and unusual receding of the ocean. If you see the shoreline pulling back a lot, exposing the ocean floor, that's a massive red flag. It often means a tsunami wave is on its way.
-
A loud roaring sound coming from the sea.
If you notice any of these, do not wait for a siren or an alert. Evacuate immediately to higher ground if you're near the water.
2. Identify Your Evacuation Route in Advance
Every coastal community should have a tsunami evacuation route. It is your responsibility to learn it before you need it. Know where the nearest high ground is and how to reach it as quickly as possible. In a tsunami situation, time is of the essence.
Practice the route with your family. If you have kids, teach them what to do and where to go, even if you are not together. If you live in an area without formal evacuation maps, identify a safe location at least 100 feet above sea level or 2 miles inland.
3. Prepare a Go-Bag
A tsunami go-bag should contain the essentials to survive for at least 72 hours away from home. This includes:
-
Bottled water
-
A flashlight and extra batteries
-
A battery-powered or hand-crank emergency radio
-
Non-perishable food (this is where a shelf-stable option like OMEALS can make a big difference)
-
A first aid kit
-
Personal hygiene items
-
Copies of important documents
-
A phone charger and power bank
-
Extra clothes and a blanket if space allows it
If you have pets, make sure to include food and items for them too.
Keep this bag by the door or in your car so it is ready to grab and go.
4. Stay Informed
Sign up for local emergency alerts from your city or region. Download emergency apps that provide tsunami and earthquake alerts in real time. When traveling to coastal areas, familiarize yourself with the local alert system. Many communities have sirens or loudspeakers that sound during a tsunami warning. Always take them seriously.
You should also keep a battery-powered or crank radio in your emergency kit so you can receive updates if the power or internet goes out.
5. Build a Home Emergency Supply
In some cases, it may be safer to shelter in place if evacuation is not possible. That means your home should always be stocked with basic emergency supplies. Have enough food, water, medications, and power sources to last at least a week.
This is especially important for people who live slightly inland or in tsunami buffer zones. Earthquakes and secondary disasters can knock out infrastructure even if your home is not directly hit by the waves.
6. Understand Local Protocols
Different regions handle tsunami alerts in different ways. Learn how your area classifies alerts. For example, some warnings are issued as watches, which mean a tsunami is possible but not confirmed. Others are full warnings, meaning a tsunami is imminent or already occurring.
Do not wait for confirmation. If there has been an earthquake and you are near the ocean, assume a tsunami may follow. Get to safety first, then look for official information later.
What About Tourists and Visitors?
Many coastal areas rely on tourism. But tourists are often the least prepared. If you are traveling to a region known for tsunami risk, take a few minutes to do your research.
When you check into a hotel or rental, ask about tsunami evacuation procedures. Note the elevation of your location. If you are on the beach, know where to go if the sirens sound. Download a tsunami alert app before you arrive.
It may feel paranoid, but it could save your life.
What to Do After a Tsunami Warning Ends
Just because the initial wave has passed does not mean the danger is over. Tsunamis often come in multiple waves, and the second or third can be even larger. Stay on high ground until officials give the all-clear.
Be cautious when returning home. Roads may be washed out. Buildings may be structurally unsound. Avoid wading through water, as it may be contaminated or hide sharp debris.
Check in with neighbors. Help those who may have been stranded or injured. Community recovery depends on mutual support.
What We Hope for, and What We Must Prepare For
Our hearts go out to everyone impacted by the recent tsunami alerts. From the people of Japan and Russia to the families in Hawaii and the Pacific Islands who spent the night on edge, we wish you safety, strength, and quick recovery the best. These events are deeply unsettling. But they are also reminders of how interconnected we all are and how fragile coastal life can be.
Natural disasters are not always predictable. But preparation is. The more you know, the more you plan, the better your odds. Talk to your family. Run drills. Check your supplies. Do not wait until the sirens start to take action.
Preparedness is not fear. It is responsibility. It is wisdom. It is what protects the people and places we love.
Among your essential supplies, be sure to include ready-to-eat, shelf-stable meals. In disaster scenarios, access to groceries or cooked food may be unavailable for days. Meals like OMEALS, which self-heat without needing electricity or fire, can be life-saving. Just a pouch of water is enough to get a hot, nutritious meal. Add a few to your emergency kit so you are never caught off guard.
The sea is beautiful, but it can also be brutal. Living near the ocean offers a connection to nature that few other places can match. But that connection comes with risk.
Do not let comfort turn into complacency. If you are on or near the Pacific Ring of Fire, tsunamis and earthquakes are part of life. You cannot control them, but you can control how ready you are when they come.
