Rogue waves are considered rare, but potentially very dangerous, since they can involve the spontaneous formation of massive waves far beyond the usual expectations of ship designers, and can overwhelm the usual capabilities of ocean-going vessels which are not designed for such encounters. Rogue waves are, therefore, distinct from tsunamis. [1]
The ship's operating at reduced speed when the waves hit probably limited the damage." [47] Aleutian Ballad, (Bering Sea, 2005): Footage of a rogue wave appears in an episode of Deadliest Catch from Season 2, Episode 4 "Finish Line" (Original airdate: 28 April 2006). While sailing through rough seas during a night time storm, a "freak wave ...
A tsunami, a series of water waves in a body of water caused by the displacement of a large volume of water, although this usage of "tidal wave" is a misnomer and is disfavored by the scientific community. A megatsunami, which is an informal term to describe a tsunami that has initial wave heights that are much larger than normal tsunamis
The unpredictability of sneaker waves and their tendency to arrive suddenly after lengthy periods of gentle, lapping waves makes it easy for them to surprise unwary or inexperienced beachgoers; [6] because they are much larger than preceding waves, sneaker waves can catch inattentive swimmers, waders, and other people on beaches and ocean jetties and wash them into the sea.
An example of this was the July 17, 1998, Papua New Guinean landslide tsunami where waves up to 15 m high impacted a 20 km section of the coast killing 2,200 people, yet at greater distances the tsunami was not a major hazard. This is due to the comparatively small source area of most landslide tsunami (relative to the area affected by large ...

[2]: 1036 Meteotsunamis, rather, are triggered due to extreme weather events including severe thunderstorms, squalls and storm fronts; all of which can quickly change atmospheric pressure. Meteotsunamis typically occur when severe weather is moving at the same speed and direction of the local wave action towards the coastline.
Wave breaking also occurs in plasmas, [2] when the particle velocities exceed the wave's phase speed. Another application in plasma physics is plasma expansion into a vacuum, in which the process of wave breaking and the subsequent development of a fast ion peak is described by the Sack-Schamel equation.
