What_is_Megatsunami_or_Global_Flood.jpgMegatsunami (often hyphenated as mega-tsunami, also known as iminami or “wave of purification”) is an informal term used to describe a very large tsunami wave beyond the typical size reached by most tsunamis (usually around 10 m).
A mega tsunami is a huge wave starting from over 40 meters (131 feet) up to giants over 100 meters (328 ft) tall. Note that the waves are often much higher when they meet land, as the water often floods upwards from the force of impact.
Mega tsunamis may be caused by rock fall and landslide phenomena, explosive volcanic events, or meteor impacts. Underwater earthquakes do not normally generate such large tsunamis; typically tsunamis caused by earthquakes (such as the 2004 Indian Ocean earthquake) have a height of less than ten meters at the shore (depending on how much water was displaced by the earthquake and on various natural factors such as tree cover and the general shore characteristics) but can affect thousands of kilometers of coastline and reach many kilometers inland.
