Tsunami
A tsunami (plural: tsunamis or tsunami; from Japanese: 津波, lit. "harbor wave";[1]English pronunciation: /suːˈnɑːmi/ soo-nah-mee or /tsuːˈnɑːmi/ tsoo-nah-mee[2]), also called a tsunami wave train,[3] and at one time incorrectly referred to as a tidal wave, is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean, though it can occur in large lakes. Tsunamis are a frequent occurrence in Japan; approximately 195 events have been recorded.[4] Owing to the immense volumes of water and the high energy involved, tsunamis can devastate coastal regions.
Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides glacier calvings[5] and othermass movements, meteorite ocean impacts or similar impact events, and other disturbances above or below water all have the potential to generate a tsunami.

Tsunami in Japan
Japan was hit by an enormous earthquake on March 11, 2011, that triggered a deadly 23-foot tsunami in the country's north. The giant waves deluged cities and rural areas alike, sweeping away cars, homes, buildings, a train, and boats, leaving a path of death and devastation in its wake. Video footage showed cars racing away from surging waves. The United States Geological Survey reported the earthquake and on Monday revised its magnitude from 8.9 to 9.0, which is the largest in Japan's history. The earthquake struck about 230 miles northeast of Tokyo. The Pacific Tsunami Warning Center issued warnings for Russia, Taiwan, Hawaii, Indonesia, the Marshall Islands, Papua New Guinea, Australia, and the west coasts the U.S., Mexico, Central America, and South America. As of Tuesday, March 22, more than 8,600 were confirmed dead. That number will likey continue to rise with more than 13,000 people still missing.
