A megatsunami is a tsunami with an initial wave amplitude ( height) measured in many tens or hundreds of metres. A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms. Normal tsunamis result from displacement of the sea floor due to plate tectonics.

How tsunamis form and why they can be so dangerous

The rockslide impact generated a giant tsunami at the head of Lituya Bay resulting in an unprecedented tsunami runup of 524 m on a spur ridge in direct prolongation of the slide axis.
