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.
Diagram of the 1958 Lituya Bay megatsunami, which proved the existence of megatsunamis. A megatsunami is a very large wave created by a large, sudden displacement of material into a body of water. Megatsunamis have different features from ordinary tsunamis. Ordinary tsunamis are caused by underwater tectonic activity (movement of the earth's ...
List of natural disasters by death toll. Global multihazard mortality risks and distribution (2005) for cyclones, drought, earthquakes, floods, landslides, and volcanoes (excluding heat waves, snowstorms, and other deadly hazards). A natural disaster is a sudden event that causes widespread destruction, major collateral damage, or loss of life ...
Tsunami. 15 to 30 m (50 to 100 ft); [2] [3] max. 51 m (167 ft) [4] Casualties. 227,898 dead [5] [6] On 26 December 2004, at 07:58:53 local time ( UTC+7 ), a major earthquake with a magnitude of 9.2–9.3 Mw struck with an epicentre off the west coast of northern Sumatra, Indonesia. The undersea megathrust earthquake, known by the scientific ...
The two arms that create the top of the T-shape of the bay are the Gilbert and Crillon inlets and are a part of a trench on the Fairweather Fault. [10] In the past 170 years Lituya Bay has had four tsunamis over 100 ft (30 m): 1854 (395 ft or 120 m), 1899 (200 ft or 60 m), 1936 (490 ft or 150 m), and 1958 (1,720 ft or 520 m). [11] [12]
Smaller (M w 4.2) earthquakes in Japan can trigger tsunamis (called local and regional tsunamis) that can devastate stretches of coastline, but can do so in only a few minutes at a time. Landslides The Tauredunum event was a large tsunami on Lake Geneva in 563 CE, caused by sedimentary deposits destabilised by a landslide.
The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, impacted Portugal, the Iberian Peninsula, and Northwest Africa on the morning of Saturday, 1 November, Feast of All Saints, at around 09:40 local time. [ 3] In combination with subsequent fires and a tsunami, the earthquake almost completely destroyed Lisbon and adjoining areas.
The following is a summary of significant earthquakes during the 21st century. In terms of fatalities, the 2004 Indian Ocean earthquake was the most destructive event with 227,898 confirmed fatalities, followed by the 2010 Haiti earthquake with about 160,000 fatalities, [ 2] the 2008 Sichuan earthquake with 87,587 fatalities, the 2005 Kashmir ...
