A tsunami hitting a coastline. This article lists notable tsunamis, which are sorted by the date and location that they occurred..

The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) on 22 May 1960 was the most powerful earthquake ever recorded. Most studies have placed it at 9.4–9.6 on the moment magnitude scale, [1] while some studies have placed the magnitude lower than 9.4.
As it approaches land, the wave height of an ordinary tsunami increases dramatically as the sea floor slopes upward and the base of the wave pushes the water column above it upwards. Ordinary tsunamis, even those associated with the most powerful strike-slip earthquakes, typically do not reach heights in excess of 30 m (100 ft). [3] [4]
Nearly two decades have passed since the deadliest tsunami in history, which killed more than 225,000 people. National Geographic is set to release a powerful four-part documentary series, called ...
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]
After the earthquake the majority of the Severo-Kurilsk citizens fled to the surrounding hills, where they escaped the first wave. However, most of them returned to the town and were killed by the second wave. [10] According to the authorities, out of a population of 6,000 people, 2,336 died. [1] The survivors were evacuated to continental Russia.
