The tsunami is a huge sea wave that suddenly comes in the coastal areas. It usually arises due to earthquakes at the ocean floor. When the layers of the earth below the sea slide and there is a heavy movement in the water, high waves are formed.
Tsunami: The word tsunami is once again in the headlines. Hearing the word tsunami, the bitter memories of the fierceness of 2004 are refreshed in the minds of the people. Who can forget that moment? Even today, the scene of destruction remains the cause of fear. According to the news agency PTI, a tsunami knocked in the coastal areas of Kuril Island in Russia and large North Island Hokkaido in Japan. The cause of the tsunami on these islands was a powerful earthquake of 8.8 magnitude on the coast of Russia. Half of the world is under threat of tsunami due to the most powerful earthquake of the decade. In such a situation, it becomes interesting to know which factor is that due to which tsunami comes.
When and why does a tsunami come?
The tsunami is a huge sea wave that suddenly comes in the coastal areas. It usually arises due to earthquakes at the ocean floor. When the layers of the earth below the sea slide and there is a heavy movement in the water, high waves are formed. Apart from this, volcanic eruptions, landslides or meteor shower can also cause tsunami. The tsunami comes when these waves travel fast in the sea and reach near the coast and become high and destructive. These waves are small and sharp in the deep sea, but due to the depth of water on the coast, their height increases. These waves can enter internal areas for several kilometers, causing heavy destruction. The main reason for the tsunami arrival is natural disasters, which are out of the control of humans. It destroys houses, roads, and crops, as well as causing heavy losses of life and property. Tsunami warning systems and awareness can reduce losses. Those living in coastal areas should be prepared for such a disaster.
How much is the speed and height of tsunami waves?
During tsunami, the speed of waves is up to 800 kilometers per hour. However, the speed of waves decreases until reaching near the coast, but their height and power increases. A strong collision on the coast of these waves also causes damage to life and property. If we talk about height, then these waves can be up to 10 to 18 meters high. Suppose these waves are like a vigorous wall on the water.
