Tsunami aftermath in Aceh, Indonesia, December 2004. Tsunamis are sometimes referred to as tidal waves. [15] This once-popular term derives from the most common appearance of a tsunami, which is that of an extraordinarily high tidal bore. Tsunamis and tides both produce waves of water that move inland, but in the case of a tsunami, the inland ...
In seismology, a tsunami earthquake is an earthquake which triggers a tsunami of significantly greater magnitude, as measured by shorter-period seismic waves. The term was introduced by Japanese seismologist Hiroo Kanamori in 1972. [1] Such events are a result of relatively slow rupture velocities. They are particularly dangerous as a large ...
An earthquake is the shaking of the surface of Earth resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes may also be referred to as quakes, tremors, or temblors. The word tremor is also used for non-earthquake seismic rumbling . In its most general sense, an earthquake is any seismic event ...
Only about 12 hours after the initial eruption, tsunami waves a few feet. On Jan. 15, 2022, coastal areas across California were placed under a tsunami warning. Gado via Getty ImagesOn Jan. 15 ...
A meteotsunami or meteorological tsunami[ 1] is a tsunami -like sea wave of meteorological origin. Meteotsunamis are generated when rapid changes in barometric pressure cause the displacement of a body of water. In contrast to impulse-type tsunami sources, a traveling atmospheric disturbance normally interacts with the ocean over a limited ...
A megatsunami is a tsunami with an initial wave amplitude measured in many tens or hundreds of metres. A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms. Normal tsunamis result from displacement of the sea floor due to movements in the Earth's crust (plate tectonics).
684 Hakuhō earthquake, Nankai earthquake. Earthquake. The first recorded tsunami in Japan struck on 29 November 684 AD off the coast of the Kii, Shikoku, and Awaji region. The earthquake, estimated at a magnitude of 8.4, [40] was followed by a large tsunami, but there are no estimates of the number of deaths. [56]
The Tsunami portal. A tsunami ( / ( t) suːˈnɑːmi, ( t) sʊˈ -/ (t)soo-NAH-mee, (t)suu-; from Japanese: 津波, lit. 'harbour wave', pronounced [tsɯnami]) 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. Earthquakes, volcanic eruptions and other underwater ...
