A tsunami in common usage is an ocean wave generated by earthquakes or other geological events, including asteroid impacts, under the sea or related collapses of continental shelves. A tsunami is preceded by a stage known as 'drawback' during which the coastal waters may recede for hundreds of metres before the tsunami arrivesTechnically they are in fact a series of waves. Tsunamis have great destructive power, and may travel across oceans before making landfall. Some of the most destructive tsunamis occur in the areas adjacent to major earthquakes. |
Examples of Tsunami:
The 2004 Indian Ocean tsunami devastated the region, killing thousands of people in South East Asia. A Megatsunami was recorded in 1958 at Lituya Bay in Alaska, with a height of 524 metres or 1720 feet. The tsunami occurred in a fjord, raising its height. https://www.ess.washington.edu/tsunami/index.html https://www.det.wa.edu.au/education/cmis/eval/curriculum/pathfinders/disasters/tsunamis/ https://www.tulane.edu/~sanelson/geol204/tsunami.htm https://en.wikipedia.org/wiki/Tsunami |
