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.

A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
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.

Tilly Smith (born 1994) is a British woman who, as a child, was credited with saving the lives of approximately 100 beachgoers at Mai Khao Beach in Thailand by warning them minutes before the arrival of the tsunami caused by the 2004 Indian Ocean earthquake.
The tsunami destroyed over 7,000 homes along the northern Japanese coastline, of which over 4,885 were washed away. The tsunami was also recorded in Hawaii with a height of 9.5 feet (2.9 m), and also resulted in slight damage. [2] The death toll came to 1,522 people confirmed dead, 1,542 missing, and 12,053 injured.
