Explanation:
INTRODUCTION:
Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depth of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters. While tsunamis are often referred to as tidal waves, this name is discouraged by oceanographers because tides have little to do with these giant waves.
CAUSES OF TSUNAMI:
Some of the major reasons for formation of tsunamis are as follows:
A) Undersed earthquakes:
Although tsunami may be caused by landslides, volcanic eruptions or even by the impact of a large meteorite falling on the ocean, most destructive tsunamis are generated by massive undersea earthquakes, occurring at depth less than 50 km with the epicentre or fault line near or on the ocean floor.
B) Landslides:
Tsunami waves are also generated by displacement of seawater resulting from landslides as well as rock falls, icefalls etc. Construction work of an airport runway along the coast of Southern France in the 1980s caused an underwater landslide.
This triggered the destructive tsunami waves in the harbour of Thebes. Underwater landslides may also occur when a strong earthquake shakes the sea floor, thus forming tsunamis. These waves rapidly travel away from the source due to dissipation of energy, and create havoc in the nearby coastlines.
C) Volcanic Eruptions:
Whenever a violent volcanic eruption takes place under the sea, it causes sudden displacement of a large volume of seawater and tsunami waves are formed. Similarly, when the roof of a volcano collapses that has a large empty magma chamber owing to continuous flow of lava, a crater sometimes as large as one kilometer in diameter is formed. As the seawater gushes into this crater, the water column of the sea is disturbed which gives rise to tsunami waves.
D) Meteorites and Asteroids:
There is a potential danger of tsunami being formed by the fall of meteorites and asteroids in the ocean. Researchers in California have developed a computer simulation depicting the ocean impact of asteroid 1950 DA, a gigantic space rock that would be very close to the earth in 2880.
Although the possibility of such an impact is very remote, the computer model definitely gives the researcher an insight into the destructive power of tsunami caused by near-Earth object. Some of the meteorites have been uncomfortably close to the earth and could wreck havoc in different forms including tsunamis.
EFFECTS OF TSUNAMI:
- The effects of a tsunami are devastating. They are one of the world's worst natural disasters that can hit a country.
- Tsunami damage is first caused by the immense force of the tidal wave hitting the shoreline. Tsunami flooding then continues to cause damage for several more weeks.
- The effects of the tsunami on the country during this period range from destruction and damage, death, injury, millions of dollars in financial loss, and long lasting psychological problems for the inhabitants of the region.
- The initial impact of the tsunami is often publicised across the world through the news media. However, the actual effects continue for many years after the natural disaster strikes.
- For many of the people affected, they will never forget the terrifying ordeal of being caught in a tsunami. The scars that are inflicted on the land can be present for decades to come, and this only serves as a reminder to people living in the area of the terrible losses caused by the tsunami, and the lingering danger that yet another killer tidal wave could strike at any moment with very little warning.
REMEDIES OF TSUNAMI: (precautions)
To escape a tsunami, go as high and as far as you can – ideally to a spot 100 feet above sea level or 2 miles away.
Every foot inland or upward may make a difference.
If you can see the wave, you are too close for safety.
Avoid building or living in buildings within several hundred feet of the coastline.
If you do live in a coastal area, elevate your home to help reduce damage.
Take precautions to prevent flooding.
Have an engineer check your home and advise about ways to make it more resistant to tsunami water.
TSUNAMI PRONE AREA OF THE WORLD:
About 30% of Pacific tsunamis occurs in the region of Japan-Taiwan and the coasts of Japan are particularly prone to tsunami due to the occurrence of a relevant number of submarine earthquakes. Nevertheless, both destructive and minor tsunamis occur also in the Indian ocean, Atlantic ocean and in the Mediterranean sea.
