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 ...
A megatsunami is a tsunami with an initial wave amplitude measured in many tens or hundreds of metres.The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high. [2]

A piece of wood from the excavated area, above the tsunami layer, was radiocarbon dated to 930±80 years before present, suggesting the layer may be evidence of the June 16, 1026 event. [5] A water tank experiment suggest the tsunami was triggered by an undersea landslide , and a preserved landslide topography in the Sea of Japan may represent ...

The extreme tsunami was likely the result of a submarine landslide.
