Tsunami (Japanese: 津 波; tsu = harbor, nami = wave, literally means "big waves in the harbor") is the transfer of water bodies caused by changes in sea surface vertically with a sudden. Changes in sea level can be caused by an earthquake centered under the sea, underwater volcanic eruptions, underwater landslides, or meteor in the sea or blow. Tsunami waves can propagate in all directions. Energy contained in the tsunami wave height is fixed to the function and kelajuannya. In the deep ocean, tsunami waves can propagate with the speed of 500-1000 km per hour. Equivalent to the speed of the aircraft. Deep-sea wave height is only about 1 meter. Thus, the rate of the waves are not felt by the ships which were in the middle of the sea. As they neared the shore, tsunami wave speed decreases to about 30 km per hour, but its height was increased to tens of meters. Tsunami waves hit can go up to tens of kilometers from the shoreline. Damage and casualties due to Tsunami can be caused due to hit the water and the material carried by the flow of tsunami waves.
The negative impact caused by the tsunami was damaging anything in its path. Buildings, plants, and resulted in human casualties and cause flooding, saltwater contamination of agricultural land, soil, and water.
The Greek historian Thucydides was the first name that associates with the undersea earthquake tsunami. But until the 20th century, knowledge about the cause of tsunami is still very minimal. Research is still underway to understand the causes of tsunami.
Texts of geology, geography, and oceanography in the past called tsunamis as "seismic sea waves".
Some meteorological conditions, such as tropical cyclones, storm surges can cause the so-called meteor tsunami height several feet above normal sea waves. When the storm reaches land, the shape can resemble a tsunami, although not a tsunami. Wave could inundate the land. This storm surge had inundated Burma (Myanmar) in May 2008.
The area around the Pacific Ocean has the Pacific Tsunami Warning Centre (PTWC) issued a warning that if there is a tsunami threat in this region. The area around the Indian Ocean Indian Ocean were building Tsunami Warning System (IOTWS) will be based in Indonesia.
Historical evidence suggests that megatsunami may have occurred, which caused some islands to sink
