The extraordinary type of ocean wave not related to the wind or tidal wave is often referred to as the Tsunami. It is produced due to the seductions of the ocean floor or due to the eruption of the volcano, meteorite impacts etc., in the seabed. Due to the reduction of a large amount of area the disturbance to seawater can be high leading to larger waves. Occasionally banks of the larger lakes can also suffer from massive tidal wave or the tsunami.
Tides are normally generated from the gravitational pull of the moon and the earth. The waves of the tsunami are larger than thirty meters and can last from several minutes to hours. Series of the wave is often referred to as wave train occurs at the time of Tsunami occurrence. Due to the humongous nature Tsunami is the cause of the massive destruction of life and property of the low-lying coastal areas.
Tsunami is the word originates from Japanese. Sometimes seismic sea wave is often used to describe the tsunami before the wide use of the name.

3. Prediction of Tsunami
Tsunami is mostly due to the earthquake on the ocean floor. Despite all the advancement of technology tsunami cannot be predicted with the precise certainty. A team of the Geologist, oceanographers, seismologist jointly makes the decision about the occurrence of Tsunami.
4. The warning system in Tsunami
The place that is prone to the Tsunami has the Tsunami warning system in order to avoid the casualty. Proper education about the tsunami to the people lying in the coastal area can be effective. Evacuation of the people in the time of occurrence of the tsunami is done to minimize the casualty.
5. Ring of Fire
More than eighty percent of the Tsunami happens to the Pacific Ocean that has higher tectonic shift due to earthquake and volcano. The coalition of 26 nations has given rise to The Pacific Tsunami Warning system headquartered in Hawaii.
