How to survive a tsunami


What is a tsunami? A tsunami is a very large destructive wave originating from the sea. Most tsunamis are created by underwater earthquakes where the tectonic plates shifts and collide with each other, like an earthquake on land. When the tectonic plates shift, they move up quickly, sending thousands of gallons of water up to the surface. This results in a tsunami, tsunamis are just really big waves, the difference is that normal waves are formed by wind, this gives them a limited amount of height and speed. Tsunamis on the other hand can get as big as they can due to the fact that they are created by earthquakes or underwater landslides it depends on how high of a magnitude the earthquake is. Most tsunamis occur on fault lines since most tsunamis are created by earthquakes.

The word “tsunami” originates from the japanese meaning “harbor wave”. =harbor

How does it affect landforms? Tsunamis affect landforms due to the fact that most tsunamis are created by earthquakes which force the ocean floor up a few feet which moves a large piece of ocean floor up. This is most of the time a permanent movement. When a tsunami hits land, it can affect hills, cliffs and other large natural things. This could cause landslides and/or large pieces of land to fall off and float in a tsunami.

Safety Tip; When you see there is large pieces of debris in a tsunami wave, get out of the the way of the debris so you don’t get injured.


How are physical features affected? Physical features will be affected by tsunami due to the fact that tsunamis could reach speeds of up to 1,295 kilometers per hour, speeds of this fast are faster than an Airbus A380 flying at top speed (1,020 kilometers per hour). Tsunamis this fast will uproot trees, rocks in the ocean will likely be pulled out and come hurtling towards the shore.


How are natural resources impacted? Natural resource could be affected by tsunami not only on land, but in the ocean. When a tsunami drags back out to the ocean after the disaster, it takes debris like sticks, dirt, and other factitious and natural material back into the ocean. This causes water contamination and ocean pollution. A country most likely gets its water from the ocean will be drinking polluted, unsanitary water, especially in third world countries like Sri Lanka. on land, a tsunami would uproot trees from their roots which could be devastating for countries that use trees that bear fruits like coconut and their coconut tree supply would be largely depleted. The high waters could also drown livestock like cows, pigs, chicken, etc. Rice paddocks and fields used for harvesting foods like rice, wheat, and other grains could be unedible or lost due to the fact that when a tsunami comes in from the ocean, it distributes dirt, garbage, and other harmful debris around where the tsunami covers land.

History flashback: The 2004 Indian Ocean Tsunami claimed the lives of more than 230,000 people from all the way from thailand, to Sri Lanka, even claiming lives in Somalia in Africa. It is also one of the most costliest tsunamis in history, it costed 2.9 billion USD. 7

Evacuation Plan When you see the water has “disappeared” or moved back far into the ocean, this is a sign that a tsunami is on it’s way. Get to higher ground or move closer into the city, an average tsunami will reach into a country about 1 mile, try to move 1.5 or 2 miles into the city and away from the ocean. Follow the instructions announced by the authorities. Only return home once the autorites say it’s safe to return.

Safety Tip: When you see this warning sign, be warned, there is a good chance a tsunami can form there. Don’t ignore the warnings given out by the authorities.


Immediate impact A tsunami will most likely force businesses and schools to close. If you have children at school during the tsunami, don’t go to pick them up, the teachers and staff are trained to deal with children during disasters. If you are at work, get down underneath a desk or a sturdy object until the shaking stops, after the shaking stops, move quickly up to the top of the building.if you have pets, make sure your pets are with you at all times.

Safety tip: Since tsunamis come in multiple waves, even if you think the tsunamis over, stay where you are until the authorities tell you it’s safe to return.


After the tsunami After the tsunami has concluded and the authorities have told you it’s safe to return home, if you have children, go pick them up from school immediately. When you arrive home, try to get the water and debris outside to make your house easier to access. If your house has sustained any damage, stay outside until an official says your house is safe to live in again.


Are you at risk of tsunamis? There are many countries that are prone to tsunamis. If you see your country flag on this page, your country is at risk for tsunamis.
