    en.wikipedia.org/wiki/Tsunami

    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]

  3. Tsunami earthquake - Wikipedia

    en.wikipedia.org/wiki/Tsunami_earthquake

    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. [2]

  4. Tsunamis in lakes - Wikipedia

    en.wikipedia.org/wiki/Tsunamis_in_lakes

    Diagram showing how earthquakes can generate a tsunami. Tsunamis in lakes can be generated by fault displacement beneath or around lake systems. Faulting shifts the ground in a vertical motion through reverse, normal or oblique strike slip faulting processes, this displaces the water above causing a tsunami (Figure 1).

  6. Megatsunami - Wikipedia

    en.wikipedia.org/wiki/Megatsunami

    A megatsunami is a tsunami with an initial wave amplitude measured in many tens or hundreds of metres.The term "megatsunami" has been defined by media and has no precise definition, although it is commonly taken to refer to tsunamis over 100 metres (330 ft) high. [2]

  7. Tanabe–Sugano diagram - Wikipedia

    en.wikipedia.org/wiki/Tanabe–Sugano_diagram

    The diagram shows that there are three quartet excited states: 4 T 2, 4 A 2, and 4 T 1 (P). From the diagram one can predict that there are three spin-allowed transitions. However, the spectrum of [Co(H 2 O) 6] 2+ does not show three distinct peaks that correspond to the three predicted excited states. Instead, the spectrum has a broad peak ...

  8. Teletsunami - Wikipedia

    en.wikipedia.org/wiki/Teletsunami

    The 2004 Indian Ocean tsunami was a teletsunami.. A teletsunami (also called an ocean-wide tsunami, distant tsunami, distant-source tsunami, far-field tsunami, or trans-ocean tsunami) is a tsunami that originates from a distant source, defined as more than 1,000 km (620 mi) away or three hours' travel from the area of interest, [1] [2] sometimes travelling across an ocean.

  9. Volcanic tsunami - Wikipedia

    en.wikipedia.org/wiki/Volcanic_tsunami

    A volcanic tsunami, also called a volcanogenic tsunami, is a tsunami produced by volcanic phenomena. About 20–25% of all fatalities at volcanoes during the past 250 years have been caused by volcanic tsunamis. The most devastating volcanic tsunami in recorded history was that produced by the 1883 eruption of Krakatoa. The waves reached ...
