There are many natural disasters that occur in the world. But one of the deadliest natural disasters that destroy everything comes in their way and kills millions of people is Tsunami. It is the most powerful and savage natural disaster that the world has ever seen.
So what is a Tsunami?
The tsunami is also known as Seismic sea waves that occur with a series of continuous ocean waves generated by underwater disruption by earthquake, volcanic eruption or giant meteorite strike. A Tsunami is also known as tidal waves. A tsunami occurs when the tectonic plates move with respect to each other. The tectonic plates are so huge that their movement causes huge tsunamis.
- Tsunami waves can reach up to a height of 100 feet or more than that.
- The wavelength of a tsunami can reach up to a distance of 200 kilometers which is more than that of a normal ocean waves
- The killer waves travel up to a speed of more than 500 miles per hour.
- A tsunami is not actually one big wave but it is a series of wave called Wave train.
- Before the tsunami hits the shore it creates a huge vacuum effect sucking a huge amount of water from the beaches.
- The first wave of a tsunami is not actually the strongest but the waves follow it are stronger than it.
- Around 80 % of the tsunamis occur in the ring of fire region that lies in the Pacific region.
- Hawaii, Alaska, Washington, Oregon, and California are U.S states that are in greatest risk for tsunamis.
- At the time of tsunami occurs the huge wave losses only less energy.
- That means they can travel around the entire ocean with limited energy by retaining their energy.
- Normally the wave period of tsunami varies from a minimum of one minute sometimes a maximum of up to hours.
- Comparing with the middle of the ocean when the Tsunami waves near the shore slow down.
- But it hits with more strength and reaches maximum height.
- In Japanese Tsunami is called as Harbour waves.
- Though no one ever heard of a giant meteor strikes that cause a tsunami, Scientists still believe that a giant meteorite strike happens way back 3.5 million years ago which wipes out the entire human race.
The most powerful Earthquake
- On December 26, 2004, a massive undersea earthquake with a magnitude of 9.1 hits the coast Sumatra of the Indonesian island.
- The series of ocean waves start reaching the coast of Indian shores which causes a devastating effect.
- It is known to be the most powerful undersea earthquake that occurs till date.
- The killer wave killed at least 225000 people and destroys the livelihood of people around 12 countries.
- Indonesia, Maldives, Srilanka, India, and Thailand are the most affected countries during this massive disaster.
- More than 20000 reported missing particularly in the Srilankan and Indian region after the killer waves hit the region.
- The lack of food, drinking water and less availability of medical facility also killed many people.
How to predict a Tsunami
- Nowadays with the development of science and technology, it is easy to predict the occurrence of a tsunami.
- Half an hour before the tsunami strikes, the ocean suddenly starts to drain away. This effect is known as Drawback.
- To identify and predict the size of the tsunami, Scientists look at the size of the underwater earthquake.
- This may be helpful but not up to the full extent because the seismic waves travel faster than the tsunami and the earthquake triggers the tsunami in less than a minute.
- In 2004 researchers at the National Oceanic and Atmospheric Administration (NOAA) realize that the tsunami could probably be detected by observing the water turbulence at lower atmosphere.
- People who live in seashore must immediately vacate the place even if the observe a small amount of earthquake. Even seconds matter when you are about to get affected by the tsunami.
- Deep ocean tsunami detection buoys are one of the instruments used to find the tsunami waves undersea due to an earthquake.
Do’s and Dont’s during a Tsunami
- The first point one should ever remember during any natural disaster is to remain calm and do not panic.
- Immediately try to reach a place which is higher.
- If the Tsunami waves are accompanied by an earthquake, try to make sure that the debris won’t fall on you.
- Know whether you are in a Tsunami hazard area or not.
- Try to plan an evacuation route from the place where you are in.
- And try to distance yourself from the seashore.
- Be in touch with your local radio station to get information about any natural disasters.
- Talk to your insurance agent and know about the policy.
- Also ask whether your house, place covers under natural hazard or not.
- Some of the insurance may not cover natural disasters.
- Do not rush to the beach to see the big tidal waves.
- It may be entertainment, but a report says that the people who see the killer waves without evacuating the place are the first to lose their lives.
- Stop packing your valuable items before you evacuate the place.
- Because nothing is as valuable as your precious life.
- you can earn what you lost in the waves but no the life.
- Stop taking video footage of the tsunami, it may be cool but you may not be available to upload the video.
- If you feel that any wave lasts for a minute, you should immediately vacate the place and not wait for the official warning.
- When you stuck in the Tsunami do not try to swim.
- Rather try to grab any items that float to survive.
The killer waves don’t show mercy to anyone. It destroys everything that comes in its way. Many people lost their lives to this killer wave. The structural and economic damage causes due to the tsunami are still irreparable in many countries. We can’t stop the Tsunami but at least we can take precautionary action to avoid devastating effects. People who live in the seashore should be more aware and should listen to their local radio station and television constantly. Gather more information about the Tsunami. Every year people around the world pay homage to the people killed by Tsunami. We will constantly update more information about other natural disasters.
