This list of rogue waves compiles incidents of known and likely rogue waves – also known as freak waves, monster waves, killer waves, and extreme waves. These are dangerous and rare ocean surface waves that unexpectedly reach at least twice the height of the tallest waves around them, and are often described by witnesses as "walls of water". [1]
Rogue waves (also known as freak waves or killer waves) are large and unpredictable surface waves that can be extremely dangerous to ships and isolated structures such as lighthouses. [1] They are distinct from tsunamis , which are long wavelength waves, often almost unnoticeable in deep waters and are caused by the displacement of water due to ...
The waves are partially caused by the deposition of sediment as the river slows, as well as mixing with ocean waves. The waves, wind, and current are hazardous for vessels of all sizes. The Columbia current varies from 4 to 7 knots (7.4 to 13.0 km/h ) westward, and therefore into the predominantly westerly winds and ocean swells, creating ...
Clark Little uses his knowledge and love of surfing and the ocean to show people rare glimpses into the inside of Hawaii's most powerful waves.
Rain and dangerous high surf are battering Southern California, prompting urgent safety warnings in coastal areas after damaging waves hit earlier this week.
Monstrous waves along the California coast took onlookers by surprise Thursday. Waves as high as 20 feet "crashed over seawalls and swept away and injured several people, forced rescues and sent a ...
The "neck" is where the flow is most rapid. When the water in the rip current reaches outside of the lines of breaking waves, the flow disperses sideways, loses power, and dissipates in what is known as the "head" of the rip. Rip currents can form by the coasts of oceans, seas, and large lakes, whenever there are waves of sufficient energy.
The unpredictability of sneaker waves and their tendency to arrive suddenly after lengthy periods of gentle, lapping waves makes it easy for them to surprise unwary or inexperienced beachgoers; [6] because they are much larger than preceding waves, sneaker waves can catch inattentive swimmers, waders, and other people on beaches and ocean jetties and wash them into the sea.
