They can have extremely high initial wave heights of hundreds and possibly thousands of metres, far beyond any ordinary tsunami, as the water is splashed upwards and outwards by the impact or displacement.Īs a result, two heights are sometimes quoted for megatsunamis the height of the wave itself (in water), and the run-up, which is the height to which it surges when it reaches land, which, depending upon the locale, can be several times larger. Ordinary tsunamis have shallow waves out at sea, and the water piles up to a wave height of up to about 10 metres (33 feet) as the sea floor becomes shallow near land.īy contrast, megatsunamis occur when a very large amount of material suddenly falls into water or anywhere near water (such as via a meteor impact ), or are caused by volcanic activity. Most tsunamis are caused by underwater tectonic activity (movement of the earths plates) and therefore occur along plate boundaries and as a result of earthquake and rise or fall in the sea floor, causing water to be displaced. This was the most likely scenario of the event the PC model that was adopted for subsequent mathematical modeling studies with source dimensions and parameters provided as input. Its also possible to recover lost, and stolen licenses, as well as those located on damage storage devices.
