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 ...
The Lituya Bay megatsunami caused damage at higher elevations than any other tsunami, being powerful enough to push water up the tree covered slopes of the fjord with enough force to clear trees to a reported height of 524 m (1,719 ft). [9] A 1:675 recreation of the tsunami found the wave crest was 150 m (490 ft) tall. [14]
The possibility of a large collapse of this volcano causing a tsunami was known already before the 2018 event, [16] and the disaster drew attention to the dangers associated with non-earthquake tsunamis. [17] Other historically recorded examples include the 1929 Grand Banks earthquake, the 1958 Lituya Bay tsunami, [18] numerous tsunamis at ...

Smaller waves were recorded on tidal gauges as far away as the English Channel. [17] These occurred too soon to be remnants of the initial tsunamis, which owing to a wavelength of less than 7 km, failed to cause significant damage at large distance, [18] and may have been caused by concussive air waves from the eruption. These air waves circled ...
