A tsunami hitting a coastline. This article lists notable tsunamis, which are sorted by the date and location that they occurred.. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, [1] but are a worldwide natural phenomenon.
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]
The 1938 Banda Sea earthquake, an intermediate depth magnitude 8.5 event only caused a minor tsunami. [1] The Seram Trough is a zone of complex convergence between the Pacific, Australian, Sunda, and numerous micro tectonic plates. This megathrust fault is located north of Seram Island.

A tsunami that devastated the area around Indonesia's Sunda Strait, leaving at least 222 dead and hundreds more injured, struck fast and without warning on Saturday. While most tsunamis have ...
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]
“It requires an 8.7 to get a tsunami all the way to Japan,” Tobin said. The people who recorded the incident in Japan couldn’t have known that the ground had shaken an ocean away, in the ...
The first rudimentary system to alert communities of an impending tsunami was attempted in Hawaii in the 1920s. More advanced systems were developed in the wake of the April 1, 1946 (caused by the 1946 Aleutian Islands earthquake) and May 23, 1960 (caused by the 1960 Valdivia earthquake) tsunamis which caused massive devastation in Hilo, Hawaii.
