As early as 426 BC the Greek historian Thucydides inquired in his book History of the Peloponnesian War about the causes of tsunami, and was the first to argue that ocean earthquakes must be the cause. [12] [13] The oldest human record of a tsunami dates back to 479 BC, in the Greek colony of Potidaea, thought to be triggered by an earthquake.
The subsequent tsunami leveled 1451 houses and caused 1500 deaths in Japan, and was observed on tide gauges in California, Hawaii, and Peru. [44] The coastal cities of Kushimoto and Kainan on the Kii Peninsula were particularly hard hit. The earthquake caused more than 1400 deaths, with the tsunami being the main cause. 1947 Gisborne, New Zealand
The 2004 Indian Ocean tsunami at Ao Nang, Krabi Province, Thailand. A tsunami (/(t) s uː ˈ n ɑː m i, (t) s ʊ ˈ-/ (t)soo-NAH-mee, (t)suu-; from Japanese: 津波, lit.

The first warning sign of a possible tsunami is the earthquake itself.
[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]
