Tsunami

What Is A Tsunami?:-

A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced. Earthquakes, mass movements above or below water, some volcanic eruptions and other underwater explosions, landslides, underwater earthquakes, large asteroid impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami can be devastating due to the immense volumes of water and energy involved. Tsunami refers to "Seismic sea waves". The term tsunami comes from the Japanese meaning harbor and wave. Tsunamis are often referred to popularly as tidal waves although they have nothing to do with tides.

Signs Of A Tsunami:-

There is often no advance warning of an approaching tsunami. However, since earthquakes are often a cause of tsunami, any earthquake occurring near a body of water may generate a tsunami. Before a tsunami comes, there is a sudden drawback of water, which is the first sign of an approaching tsunami. If a person is in a coastal area where the sea suddenly draws back, their only real chance of survival is to run for high ground or seek the high floors of high rise buildings.

Destruction Caused By A Tsunami:-

Usually, a tsunami starts suddenly. It will begin as normal waves and change to a very big wave very quickly. The waves travel at a great speed across an ocean with little energy loss. They can remove sand from beaches, destroy trees, damage houses and even devastate whole towns.

Shocking Incident:-

The deadliest tsunami recorded was on December 26, 2004. It was caused by an earthquake. The earthquake was said to had magnitude 9.3 on the Richter scale. It was centered in the ocean near the coast of Sumatra, Indonesia. Over 225,000 people died from this disaster. The giant wave moved very quickly. Hundreds of thousands of people in Indonesia, Sri Lanka, Thailand, India, Somalia, and other nations, were killed or injured by it.

Preventions:-

Tsunamis cannot be prevented, but there are ways to help stop people from dying from a tsunami. Some regions with a high risk of tsunamis may use warning systems to warn the general population before the big waves reach the land. Because an earthquake that caused the tsunami can be felt before the wave gets to the shore, people can be warned to go somewhere safe.
