Tsunamis

Tsunamis form from earthquakes, volcanic eruptions, or landslides that occur under the sea. When this event happens under the water, huge amounts of energy are released as a result of quick upward bottom movement. For example, if a volcanic eruption occurs, the ocean floor will quickly move upward several hundred feet. When this happens, huge volumes of ocean water are pushed upward and a wave is formed. A large earthquake can lift thousands of square kilometres of sea floor, which will cause the formation of huge waves. The Pacific Ocean is especially prone to tsunamis.
