Top 5 Essays on Earthquakes Geography Article shared by: An earthquake is a major demonstration of the power of the tectonic forces caused by endogenetic thermal conditions of the interior of the earth.
The word tsunami is a Japanese word, represented by two characters: Tsunami is a set of ocean waves caused by any large, abrupt disturbance on the sea- surface.
If the disturbance is close to the coastline, local tsunamis can demolish coastal communities within minutes. A very large disturbance can cause local devastation and export tsunami destruction thousands of miles away.
Tsunamis rank high on the scale of natural disasters. Since alone, tsunamis have been responsible for the loss of overlives and billions of dollars of damage to coastal structures and habitats. Most of these casualties were caused by local tsunamis that occur about once per year somewhere in the world.
For example, the December 26,tsunami killed aboutpeople close to the earthquake and about 58, people on distant shores. Predicting when and where the next tsunami will strike is currently impossible. Once the tsunami is generated, forecasting tsunami arrival and impact is possible through modelling and measurement technologies.
The phenomenon we call tsunami is a series of large waves of extremely long wavelength and period usually generated by a violent, impulsive undersea disturbance or activity near the coast or in the ocean. When a sudden displacement of a large volume of water occurs, or if the sea floor is suddenly raised or dropped by an earthquake, big tsunami waves can be formed by forces of gravity.
The waves travel out of the area of origin and can be extremely dangerous and damaging when they reach the shore. It has been internationally adopted because it covers all forms of impulsive wave generation. Tsunami in the deep ocean may have very long wave length of hundreds of kilometre and travels at about km per hour, but an amplitude of only about 1 km.
It remains undetected by ships in the deep sea. However, when it approaches the coast its wavelength diminishes but amplitude grows enormously, and it takes very little time to reach its full height.
Computer model can provide tsunami arrival, usually within minutes of the arrival time. Tsunamis have great erosion potential, stripping beaches of sand, coastal vegetation and dissipating its energy through the destruction of houses and coastal structures. In the open ocean, tsunamis would not be felt by ships because the wavelength would be hundreds of miles long, with an amplitude of only a few feet.
This would also make them unnoticeable from the air. As the waves approach the coast, their speed decreases and their amplitude increases.Disaster Preparedness is for Everyone - Introduction Of the four phases of emergency management, mitigation, preparedness, response and recovery, perhaps the place that individuals can make the biggest difference in their own state of resiliency and survival of a disaster is in the preparedness phase.
