Tsunami | Definition, Meaning, & Facts | Britannica

Much like any other water waves, tsunamis are reflected and refracted by the topography of the seafloor near shore and by the configuration of a coastline. As a result, their effects vary widely from place to place. Occasionally, the first arrival of a tsunami at a coast may be the trough of the wave, in which case the water recedes and exposes the shallow seafloor.

What causes tsunamis? Most tsunamis are caused by earthquakes on converging tectonic plate boundaries.According to the Global Historical Tsunami Database, since 1900, over 80% of likely tsunamis were generated by earthquakes.However, tsunamis can also be caused by landslides, volcanic activity, certain types of weather, and—possibly—near-earth objects (e.g., asteroids, comets) colliding

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. Tsunamis are sometimes referred to as "tidal waves", but this is very

Tsunamis are caused by underwater earthquakes, volcanic eruptions or landslides that displace a large amount of water. They travel fast and get taller as they approach shore, causing flooding and strong currents that can devastate coastal areas.

0:00. / 3:05. A tsunami is a series of ocean waves generated by sudden displacements in the sea floor, landslides, or volcanic activity. In the deep ocean, the tsunami wave may only be a few inches high. The tsunami wave may come gently ashore or may increase in height to become a fast moving wall of turbulent water several meters high.
