from where can i get some information on tsunami the killer wave?

Answer 1

The Wikipedia article on tsunamis is pretty comprehensive. It describes the history of the name, the mechanisms that cause tsunamis, the effects and behavior of tsunamis on land, and information about historically significant tsunamis.

Answer 2

Tsunamis and killer waves are not the same thing.

Tsunamis are caused by seismic events and landslides. A tsunami traveling over deep water has a crest from a few inches to a few feet, and is usually not recognizable because it has a long wavelength.

Killer waves are waves on the open ocean with a crest of up to 100 ft. or 30 meters. Some are believed to be caused by wind or counter-flowing ocean currents, and some appear to be completely random events which are only explainable afterwards by application of Schrodinger Wave Equation. Only a few ships have encountered them and survived the encounter. Many have been reported in the very South Atlantic, and west of the Cape of Good Hope, but the largest recorded occurred in the North Atlantic during a severe storm.
