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 invisible ships (or ships not seen) myth claims that when European explorers' ships approached either North America, South America, or Australia, the appearance of their large ships was so foreign to the native people that they could not even see the vessels in front of them.
The rules of thumb for ship travel when a tropical cyclone is in their vicinity are to avoid them if at all possible and do not cross their forecast path (crossing the T). Those traveling through the dangerous semicircle are advised to keep to the true wind on the starboard bow and make as much headway as possible. Ships moving through the ...
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
3. The oceans are an escape. For centuries, life at sea has been romanticized as the ultimate expression of freedom — a refuge from landlocked life, far removed from government meddling, a ...
A tsunami hitting a coastline. This article lists notable tsunamis, which are sorted by the date and location that they occurred.. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, [1] but are a worldwide natural phenomenon.
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
