1 paź 2018 · A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

7 gru 2023 · Tsunamis, derived from the Japanese words "tsu" (meaning harbor) and "nami" (meaning wave), are large ocean waves with the potential to inundate coastal areas. These waves can reach staggering heights, sometimes exceeding 100 feet (30 meters) or more.
A tsunami’s trough, the low point beneath the wave’s crest, often reaches shore first. When it does, it produces a vacuum effect that sucks coastal water seaward and exposes harbor and sea...
15 sie 2023 · Tsunamis are a series of long waves generated by a large and sudden displacement of the ocean. Large earthquakes below or near the ocean floor are the most common cause, but landslides, volcanic activity, certain types of weather, and meteorites can also cause a tsunami.
19 lut 2021 · Tsunamis. The tsunamis are waves generated by sudden tectonic changes in the sea bed or landslides that are usually consequences of earthquakes and submarine volcanic activity. Their wave period is between 1 and 20 minutes, and their wavelength is between a few to hundreds of kilometers. Tsunamis have very small amplitude in deep oceans (rarely exceeding an amplitude of 1 meter) but they shoal ...
1 sty 2015 · Extreme waves mainly occur during major storms at sea by means of constructive interference of wave trains or by nonlinear wave interaction, but extreme waves may also be associated with tsunami or meteotsunami events.
2 kwi 2007 · A tsunami is a series of great sea waves caused by an underwater earthquake, landslide, or volcanic eruption. More rarely, a tsunami can be generated by a giant meteor impact with the...
