Earthquake – Tsunami Fukushima, Japan! (Compilation)
Tsunamis (Japanese: 津 波 tsunami) is a series of waves created when a large volume of ocean water was swift shifting on a large scale. Earthquakes along the great geological move above or below the water surface, volcanic eruptions and meteorite impacts have the potential to cause a tsunami. The disastrous consequences of the tsunami may be at very large, killed by immersion in water to hundreds of thousands of people in a few hours.
The term tsunami (tsunami) is derived from the Japanese word for “wharf” (津 tsu, Sino Vietnamese: “neo”) and “wave” (nami 波, “three”). The term is due to the fishermen set out at that time they did not know whether the cause is the wave comes out offshore. Tsunami originating from deep sea bottom; while outside offshore, wave amplitude (wave height) is quite small, but the length of waves up to hundreds of kilometers. So far shore when we hardly recognize it, but just felt a wave of dunes stretching.
In the West before the tsunami once considered a tidal wave (English: Tidal wave) because when carried to shore, wave acts as a powerful rising tide, unlike common types of waves generated by offshore wind . However, since not match reality, so the term is no longer used.
