Rogue waves do not appear to have a single distinct cause but occur where physical factors such as high winds and strong currents cause waves to merge to create a single large wave. [1] Recent research suggests sea state crest-trough correlation leading to linear superposition may be a dominant factor in predicting the frequency of rogue waves. [3]
Major areas of current research include determining why some large earthquakes do not generate tsunamis while other smaller ones do. This ongoing research is designed to help accurately forecast the passage of tsunamis across oceans as well as how tsunami waves interact with shorelines.
The 2004 Indian Ocean tsunami at Ao Nang, Krabi Province, Thailand. A tsunami (/(t) s uː ˈ n ɑː m i, (t) s ʊ ˈ-/ (t)soo-NAH-mee, (t)suu-; from Japanese: 津波, lit. 'harbour wave', pronounced) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
This is the third largest earthquake in recorded history and generated massive tsunamis, which caused widespread devastation when they hit land, leaving an estimated 230,000 people dead in countries around the Bay of Bengal and the Indian Ocean. May 4, 1998 A part of the island of Yonaguni was destroyed by a submarine earthquake. May 22, 1960
The video culminates by showing the North Sea’s “raw power” about to split a ship in half. Yikes! As much as viewers are on the sailors' sides, some NorthSeaTok fans wonder why the waters ...
A January 23, 1873 memo directed the New Orleans Signal Observer to transcribe meteorological data from the ship logs of those arriving in port. [2] Marine forecasting responsibility transferred from the United States Navy to the Weather Bureau in 1904, which enabled the receipt of timely observations from ships at sea. [3]
Coral, important for bird and fish life, also needs to grow vertically to remain close to the sea surface in order to get enough energy from sunlight. So far it has been able to keep up, but might not be able to do so in the future. [77] These ecosystems protect against storm surges, waves and tsunamis.
An example of this was the July 17, 1998, Papua New Guinean landslide tsunami where waves up to 15 m high impacted a 20 km section of the coast killing 2,200 people, yet at greater distances the tsunami was not a major hazard. This is due to the comparatively small source area of most landslide tsunami (relative to the area affected by large ...
