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 ...
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]
They are nearly unnoticeable in deep water and only become dangerous as they approach the shoreline and the ocean floor becomes shallower; [14] therefore, tsunamis do not present a threat to shipping at sea (e.g., the only ships lost in the 2004 Asian tsunami were in port.).
Tsunamis generally consist of a series of waves, with periods ranging from minutes to hours, arriving in a so-called "wave train". [11] Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous, and they can affect entire ocean basins.
Coraline (2009) Besides being an amazing feat of stop-motion animation (from some of the same people who did The Nightmare Before Christmas), this creepy kids' movie is ultimately about ...
The US east coast is suddenly struck by a type of a massive destructive force of nature usually only happening after a major earthquake in the Pacific and Indian Ocean rims: tidal waves of the destructive tsunami type. Scientist and fiction author John McAdams is forced to attend a type of Department of Homeland Security conference which ...
