A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. The effects of tsunami will bring a lot of problem to the nation and community. The effects of tsunami will bring a lot of problem to the nation and community . The general cause of tsunami is earthquakes and it will makes environmental impact and destruction. Firstly,the main cause of tsunami is from the effect of earthquakes. Tsunami, also called seismic sea waves or, incorrectly, tidal waves, generally are caused by earthquakes.
Earthquakes can brings volcanic eruptions following to produce a truly awesome tsunami waves . For example ,the Great Kratatau Volcanic Eruption of 1883 generated giant waves reaching heights of 125 feet above sea-level, killing thousands of people and wiping out numerous coastal villages . Actually not all earthquakes generate tsunamis. To generate tsunamis, earthquakes must occur underneath or near the ocean, and must be large . Tsunami can happened in everywhere in the world , but in the Pacific Ocean there is a much more frequent occurrence of large because of the many large earthquakes along the margins of the Pacific Ocean.
On the other hand,the effect of tsunami is it will brings environmental impact. Tsunami will destroy all the living things and then brings unbalanced of environment. The up root of trees and plants will destroys animal habitats. Land animals are killed by drowning and the sea animals are killed and poisoned by pollution if dangerous chemicals are broken and washed away into the sea . Besides, the solid waste and disaster debris also be a part of critical problem that have to face by government .
Contamination of soil and water will affect the soil fertility of agricultural lands . For example, it may happened radiation resulting from damage to nuclear plants as it happened in Japan in March 2011. It will require a big cost and very long of time to government to recover the whole environment. The following effect by tsunami is detrimental destruction. The amount of energy and water contained in a huge tsunami can cause extreme destruction when it strikes land. The initial wave of huge tsunami keeps rising fast and floods powerfully into the coastal area.
When the giant breaking waves of a tsunami batter the shoreline, they can destroy everything in their path such as boats, buildings, bridges, cars, trees, telephone lines, power lines – and just about anything else in their way. Once the tsunami waves have knocked down infrastructure on the shore they may continue to travel for several miles inland, sweeping away more trees, buildings, cars and other man made equipment. In conclusion, all of the people should be educated and improve the knowledge on tsunami issue in order to protect themselves.
