  2. Megatsunami - Wikipedia

    en.wikipedia.org/wiki/Megatsunami

    The asteroid linked to the extinction of dinosaurs, which created the Chicxulub crater in the Yucatán Peninsula approximately 66 million years ago, would have caused a megatsunami over 100 metres (330 ft) tall. The height of the tsunami was limited due to relatively shallow sea in the area of the impact; had the asteroid struck in the deep sea ...

    Small tsunamis can also be caused by intense coastal storms, according to the U.S. Tsunami Warning System. These are known as meteotsunami because they are caused not by underwater earthquakes or ...

  4. 1958 Lituya Bay earthquake and megatsunami - Wikipedia

    en.wikipedia.org/wiki/1958_Lituya_Bay_earthquake...

    The Lituya Bay megatsunami caused damage at higher elevations than any other tsunami, being powerful enough to push water up the tree covered slopes of the fjord with enough force to clear trees to a reported height of 524 m (1,719 ft). [9] A 1:675 recreation of the tsunami found the wave crest was 150 m (490 ft) tall. [14]

  5. 1896 Sanriku earthquake - Wikipedia

    en.wikipedia.org/wiki/1896_Sanriku_earthquake

    From the tsunami records the estimated tsunami's magnitude is (M t = 8.2), [6] much greater than expected for the seismic magnitude estimated from the observed seismic intensity (M s =7.2). [2] This earthquake is now regarded as being part of a distinct class of seismic events, the tsunami earthquake .

  6. 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]

    The uplift at Cape Muroto, Kōchi is estimated at 2.3 m (7 ft 7 in) in 1707 compared to 1.5 m (4 ft 11 in) in 1854, the presence of an area of seismic intensity of 6–7 on the JMA scale in Kawachi Plain, the degree of damage and inundations heights for the corresponding tsunami and records of tsunami at distant locations, such as Nagasaki and ...

  9. 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.
