Tsunami
TSUNAMI
Introduction
1. Tsunami is a Japanese word meaning “Harbor water”. Tsunami is in most cases the result of sea-bed earthquake. The latest tsunami was the largest of its type since the magnitude Good Friday earthquake of Alaska in 1964. It took a death toll of about 200,000 people and immense property. Since last 100 years, this has been the greatest disaster that the Asian region suffered. It measured 8.9 in the Richter scale and generated a gigantic tidal surge that shuttered the coastal area of the region. The world seemed to have been stunned; lives seemed to have been startled.
2. 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. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calving, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.
3. Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves. Tsunamis generally consist of a series of waves with periods ranging from minutes to hours, arriving in a so-called "wave train". Wave heights of tens of meters can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous and they can affect entire ocean basins; the 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history with over 230,000 people killed in 14 countries bordering the Indian Ocean
