The word "tsunami" has its origin in the Japanese words for harbor "tsu" and wave "nami". A tsunami event is more likely to occur in the Pacific Ocean region. The most destructive part of a tsunami is traveling behind that initial wave. That accumulation of energy is what causes chaos and destruction. A Ruthless Wave Train It's impossible to predict a tsunami because you can't predict earthquakes, landslides all the other events that lead to its creation.
Here's what you should do when a tsunami warning is issued: 1. Don't Wait a Second Longer: Evacuate Once a tsunami alert has been issued, evacuate as soon as possible. Keep a Distance From Infrastructures Because tsunamis and earthquakes are often connected, try to evacuate to open areas with few man-made infrastructures.
Stay Informed: Listen to the Radio and Check Out the Internet Whenever possible, stay tuned to emergency information and alerts via local radio stations.

Caught in the swirling water, he clung to a piece of debris for hours before meeting another survivor and climbing onto the roof of a house as it floated by, he told interviewers decades later.
Meanwhile, the tsunami swept across the Pacific. But these mega waves can strike in any ocean , and travel across the sea to cause mayhem far from their source about twice per decade.
Most people do not survive being swept into a tsunami. But there are a few ways you can protect yourself from these natural disasters.
Your exact strategy will depend on where you are, and will go a lot more smoothly if you have planned in advance. Most tsunamis are triggered when earthquakes near the seafloor displace a large amount of water.
That water gets pushed out as a series of waves that move outwards in all directions. Undersea volcanic eruptions , landslides, and even meteorites can also spark tsunamis. Out on the sea, these waves can be hundreds of miles long but no taller than a few feet and travel at the speed of a jet plane, up to miles per hour. When the waves approach land, they will slow to about 20 or 30 miles an hour and begin to grow in height. Most tsunamis are less than 10 feet high when they hit land, but they can reach more than feet high.
When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger.
However, tsunamis can surge up to 10 miles inland. The tsunami could resemble a wall of water or, more likely , a rapidly rising flood. After a strong coastal quake, make sure you get to high ground even if an official tsunami warning has not yet been issued.
If a local tsunami has been generated it could be mere minutes away. There may be a roaring noise like a train or jet plane as well. So be on the lookout for official warnings , sirens, and directions from your local authorities. If you happen to be on a boat in the open ocean, stay there. Otherwise, your best course of action depends on how much time you have before the tsunami arrives.
Try to reach someplace feet above sea level or two miles away from the ocean. Take a disaster kit if you have one on hand, and bring your pets with you. But pay attention to any instructions from emergency personnel, since they may recommend a different evacuation route than you were planning to take. As you head for high ground, stay away from rivers and streams. And plan to evacuate on foot.
