tsunami pictures A tsunami (plural: tsunamis or tsunami, Japanese: 娲 ユ 尝, “harbor wave” bed, English pronunciation:. / Your 藧 藞 n 萍 藧 km / soo-nah-mee or / tsu 藧 藞 n 萍 藧 km / Tsoo-nah-mee) is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean or a lake. tsunami pictures Earthquakes, volcanic eruptions and other underwater explosions (including explosions of underwater nuclear devices), landslides calving, meteor strikes and other disturbances above or below water have the potential to generate a tsunami.
Tsunami waves do not resemble normal waves, because its wavelength is much longer. Instead of appearing as a tidal wave, a tsunami may instead initially looks like a rapidly rising tide, and for this reason they are known as tidal waves often.tsunami pictures Tsunamis generally consist of a series of waves with periods ranging from several minutes to several hours to reach a so-called “wave train.” The wave height of several tens of meters can generate large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous and can affect the ocean basins, the tsunami in the Indian Ocean in 2004 was one of the worst natural disasters in human history, with more than 230,000 people in 14 countries around the Indian Ocean.tsunami pictures
The Greek historian Thucydides suggested in the late fifth century BC, History of the Peloponnesian War, the tsunami is related to earthquakes submarines , ,tsunami pictures but understanding the nature of a tsunami remained slim until the 20th century and still a lot of unknowns [CLEAR]. The main areas of current research include trying to determine why some large earthquakes do not generate tsunamis, while the smallest are,tsunami pictures trying to accurately predict the passage of tsunamis across the oceans, and also to predict how tsunami waves interact with specific costs.
