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.
The Ancient Greek historian Thucydides suggested in his 5th century BC History of the Peloponnesian War that tsunamis were related to submarine earthquakes, [12] [13] but the understanding of tsunamis remained slim until the 20th century, and much remains unknown. Major areas of current research include determining why some large earthquakes do ...
It was the first detailed documentation of a tsunami in Indonesia and the largest ever recorded in the country. [1] The exact fault which produced the earthquake has never been determined, but geologists postulate either a local fault, or a larger thrust fault offshore. The extreme tsunami was likely the result of a submarine landslide.
A tsunami earthquake can be defined as an undersea earthquake for which the surface-wave magnitude M s differs markedly from the moment magnitude M w, because the former is calculated from surface waves with a period of about 20 seconds, whereas the latter is a measure of the total energy release at all frequencies.

The 479 BC Potidaea tsunami is the oldest record of a paleotsunami in human history. [1] The tsunami is believed to have been triggered by a M s 7.0 earthquake in the north Aegean Sea . The associated tsunami may have saved the colony of Potidaea from an invasion by Persians from the Achaemenid Empire .
The 2004 Indian Ocean earthquake and tsunami occurred on Sunday, December 26, 2004. The earthquake itself, with a moment magnitude of around 9.2-9.3, devastated Aceh Province, Indonesia, while the tsunami affected countries all around the Indian Ocean. Nations which were affected are listed below in alphabetical order.
A deadly swell struck Peru’s northern coastline triggering tsunami-like waves that ravaged local communities and forced 75 percent of the nation’s ports to close, potentially devastating local ...
[1] [2] Thucydides inquired into its causes, and concluded that the tsunami must have been caused by an earthquake. [3] He was thus historically the first known to correctly interpret the cause of a tsunami as a preceding geological event. [4] Herodotus, in contrast, had attributed the Potidaea tsunami to the divine wrath of Poseidon. [5]
