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 magnitude 9.2 temblor, the second most powerful earthquake ever recorded globally, caused widespread damage in the Anchorage area in 1964 and killed 131 people, including some in Oregon and California by the ensuing tsunami. Most destructive tsunamis. In 2004, a magnitude 9.1 earthquake occurred off Sumatra, an Indonesian island in the Indian ...
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]
Studies of the earthquake has placed the moment magnitude (M w ) of this earthquake at 9.0 to 9.3 and the surface-wave magnitude at 8.3 to 8.5. [3] [4] The tsunamis generated by this earthquake is thought to be the most destructive and largest ever sourced from the region, alongside the 1952 earthquake. It is thought to be similar in size or ...
A 3-metre (9.8 ft) tsunami caused moderate damage to the port and airport facilities on Simeulue, and a 2-metre (6.6 ft) tsunami was recorded on the west coast of Nias. [21] Much smaller waves, most detectable only in tide gauge recording systems, were recorded across the Indian Ocean; for example, a 0.21m wave was recorded at Colombo, Sri Lanka.
While earthquakes as large as 6.5 or below are very unlikely to trigger a tsunami and those between 6.5 and 7.5 do not usually produce destructive tsunamis, ... which was the most powerful to ...
