Explain me what about tsunamis?

Submitted by: Muhammad
A tsunami is a series of ocean waves with very long wavelengths (typically hundreds of kilometres) caused by large-scale disturbances of the ocean, such as:

earthquakes
landslide
volcanic eruptions
explosions
meteorites
These disturbances can either be from below (e.g. underwater earthquakes with large vertical displacements, submarine landslides) or from above (e.g. meteorite impacts). They are not caused by tropical cyclones.
