A very large and destructive wave, generally caused by a tremendous disturbance in the ocean, such as an undersea earthquake or volcanic eruption
{i} Great Tsunami of December 26th 2004, devastating tsunami that occurred on December 26, 2004 which was triggered by an earthquake and caused about 225,000 casualties in 8 countries (Thailand, India, Indonesia, Malaysia, Maldives, Seychelles, Somalia and Sri Lanka) on 2 continents, 2004 Tsunami
A large and often destructive wave caused by a submarine earthquake Colloquially known as a "tidal wave"
{i} (Japanese) great sea wave caused by an underwater earthquake or underwater volcanic eruption
One or a series of huge sea waves caused by earthquakes or other large-scale disturbance of the ocean floor (Referred to incorrectly by many as a tidal wave, but these waves have nothing to do with tides ) The word tsunami is Japanese, meaning "harbor wave "
An ocean wave generated by a submarine earthquake, volcano or landslide (Also known as a seismic sea wave, and incorrectly as a tidal wave)
A Japanese term which has been universally adopted to describe a large seismically generated sea wave which is capable of considerable destruction in certain coastal areas, especially where underwater earthquakes occur although in the open ocean the wave height may be less than 1 m, it steepens to heights of 15 m or more on entering shallow water They have been incorrectly referred to as tidal waves
A large, high-velocity wave generated by displacement of the sea floor (such as sudden faulting, landsliding, or volcanic activity); also called seismic sea wave Commonly misnamed TIDAL WAVE See Figure 10
A giant wave, initiated by a sudden change (usually in relative position of underwater tectonic plates) The sudden change is typically enough to propagate the wave; however, its power can be enhanced and fed by lunar positioning and boundaries that focus its energy
A sea wave produced by large-area displacements of the ocean bottom, the result of an earthquake or volcanic activity
An ocean wave generated by a submarine earthquake, volcano or landslide (Also known as a seismic seawave, and incorrectly as a tidal wave)
A Japanese term used in English to describe a giant wave produced by an earthquake or underwater volcanic eruption
A vast sea wave caused by the sudden dropping or rising of a section of the sea floor following an earthquake Tsunami may be as much as 30 meters high and 200 kilometers long, may move as fast as 250 kilometers per hour, and may continue to occur for as long as a few days
wave caused by underwater earthquake or landslide, can rise to great heights and cause catastrophic damage near coasts
A seismic sea wave usually caused by a submarine earthquake A Tsunami Warning is generally automatically issued after an earthquake of Richter 6 8 offshore Alaska, or Richter 7 5 if offshore the western U S or British Columbia A Warning means immediate evacuation of low lying areas is required A Watch means a Warning may follow Authorities will cancel Watches and Warnings whenever sufficient information permits the decision Emergency workers and the news media must know (1) the difference between a Watch and a Warning, and (2) that a tsunami may consist of several waves over several hours It is not, repeat not, just one single wave
Large ocean wave created from an earthquake or volcanic eruption Open ocean wave height may be as high as 1 meter When entering shallow coastal waters, land configuration can amplify waves to heights of over 15 meters
A sea wave produced by large-scale, short-duration disturbance of the ocean floor such as from subsidence, an earthquake, or a volcanic eruption
A sea wave of local or distant origin that results from large-scale seafloor displacements associated with large earthquakes, major submarine slides, or exploding volcanic islands (See also Earthquake ABC's )
An ocean wave produced by a submarine earthquake, landslide, or volcanic eruption These waves may reach enormous dimensions and have sufficient energy to travel across entire oceans They proceed as ordinary gravity waves with a period between 15 and 60 minutes Tsunamis steepen and increase in height on approaching shallow water, inundating low-lying areas; and where local submarine topography causes extreme steepening, they may break and cause great damage Tsunamis have no connection with tides ; the popular name is entirely misleading
a large ocean wave usually caused by an underwater earthquake or a volcanic explosion
Large seismic waves produced by earthquakes, volcanic eruptions or underwater landslides (also called tidal waves)
A shallow water progressive wave, potentially catastrophic, caused by an underwater earthquake or volcano
a great sea wave produced by an earthquake or volcano eruption under the sea and also known as a tidal wave
An ocean wave with a long period that is formed by an underwater earthquake or landslide, or volcanic eruption It may travel unnoticed across the ocean for thousands of miles from its point of origin and builds up to great heights over shallower water Also known as a seismic sea wave, and incorrectly, as a tidal wave
A tsunami is a very large wave, often caused by an earthquake, that flows onto the land and destroys things. = tidal wave. a tidal wave. or seismic sea wave or tidal wave Catastrophic ocean wave, usually caused by a submarine earthquake. Underwater or coastal landslides or volcanic eruptions also may cause tsunamis. The term tsunami is Japanese for "harbour wave." The term tidal wave is a misnomer, because the wave has no connection with the tides. Perhaps the most destructive tsunami ever occurred in 2004 in the Indian Ocean, after an earthquake struck the seafloor off the Indonesian island of Sumatra. More than 200,000 people were killed in Indonesia, Thailand, India, Sri Lanka and other countries as far away as Somalia on the Horn of Africa
A wave generated by seismic activity Also called a seismic sea wave, or erroneously a tidal wave Barely discernible in the open ocean, the amplitude of a tsunami may increase greatly as it approaches shallow coastal waters They typically have periods greater than 10 minutes Storm tide recorders along the Queensland coastline have detected the effects of events in Central and South America
