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 ...
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]
The 2011 Tōhoku earthquake had a significant impact on the nation of Japan, including one of its most well-known economic sectors, the video game industry.The damage to Japan's infrastructure prompted delays in software and hardware releases, and also caused outright cancellations when the subject matter of the software was considered too similar to real-life events.
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 ...
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 last 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 ...
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.
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.).
Thailand was one of the 14 countries affected by the 2004 Indian Ocean earthquake and tsunami on 26 December 2004. It left behind unprecedented damage and destruction in six provinces of Thailand, impacting 407 villages, completely destroying 47 of them, including prominent tourist resorts like Khao Lak. The disaster killed about 5,400 people ...
