The giant wave runup of 1,720 feet (520 m) at the head of the Bay and the subsequent huge wave along the main body of Lituya Bay which occurred on July 9, 1958, were caused primarily by an enormous subaerial rockfall into Gilbert Inlet at the head of Lituya Bay, triggered by dynamic earthquake ground motions along the Fairweather Fault.

The magnitude 9.5 earthquake of 22 May 1960, the largest earthquake ever recorded, generated one of the most destructive tsunamis of the 20th century. The tsunami spread across the Pacific Ocean, with waves measuring up to 25 metres (82 ft) high in places. The first tsunami wave hit Hilo, Hawaii, approximately 15 hours after its origin. The ...
It was the first detailed documentation of a tsunami in Indonesia and the largest ever recorded in the country. [1] The exact fault which produced the earthquake has never been determined, but geologists postulate either a local fault, or a larger thrust fault offshore. The extreme tsunami was likely the result of a submarine landslide.
In February 2000, the British oceanographic research vessel RRS Discovery, operating in the Atlantic Ocean over the Rockall Trough west of Scotland, encountered the largest waves ever recorded by scientific instruments in the open ocean, with a significant wave height of 29.1 metres (95 ft) and individual waves up to 18.5 metres (61 ft).

A tsunamis recorded along the eastern coast of North America in 1755 may have been linked to the massive earthquake struck the Portuguese capital city. That quake likely registered between a ...

Amplitude, Wave Height, or Tsunami Height: Refers to the height of a tsunami relative to the normal sea level at the time of the tsunami, which may be tidal High Water, or Low Water. It is different from the crest-to-trough height which is commonly used to measure other type of wave height.
