Huge ocean waves gif series#
"harbour wave" is a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake.Įarthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami. Here is the wikipedia description for reference, with a few more detailsĪ tsunami (plural: tsunamis or tsunami from Japanese: 津波, lit. Seismic sea waves is also another term to describe tidal waves. The French word for tsunami is raz de maree, which means the power, cutting of the sea. The German word for tidal wave is Flutwelle that literally means flood wave which is perhaps a good description. Although again historically people in harbour areas were/are most at risk of these devasting waves. The word tsunami comes from the Japanese word meaning "harbour wave" but does not have much to do with harbours. Although it is understandable to use the term since historically it looks like the tide suddenly rushes away and crashes back down as a large wave. Scientists don't like the expression tidal wave because tides are caused by the moon.
There is sometimes a bit of an argument about what is the correct term to use. An animation of the earthquake waves in 1833 similar to the Indonesia tsunami of 2004 Image: adapted from Geoscience Australia simulation
