The term "tsunami" is a borrowing from the Japanese tsunami 津波, meaning "harbour wave."For the plural, one can either follow ordinary English practice and add an s, or use an invariable plural as in the Japanese. [14]
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 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. 'harbour wave', pronounced) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
A tsunami and seiche in Lake Tahoe can be treated as shallow-water long waves as the maximum water depth is much smaller than the wavelength. This demonstrates the impact that lakes have on tsunami wave characteristics, which is different from ocean tsunami wave characteristics because the ocean is deeper, and lakes are relatively shallow in ...
The 1026 Manju tsunami affected the Sea of Japan coast of then Iwami Province on June 16. Considered one of the largest tsunamis in the Sea of Japan, it generated a tsunami with waves of 10 m (33 ft) at present-day Masuda, Shimane .
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.

Tsunami modelling executed by the University of Tokyo and Building Research Institute of Japan computed the tsunami to be 3.6 m (12 ft) in Suzu; 3 m (9.8 ft) in Noto; 2.5 m (8 ft 2 in) in Shika and 2 m (6 ft 7 in) in Jōetsu, Niigata. [101] Flooding by the tsunami exceeded 4 m (13 ft) along the east and western part of the peninsula.
