Unlike the rogue wave, which is a single wave that is up to 100 feet high, a
tsunami
is a series of waves. Tsunamis are caused by landslides, volcanoes, or earthquakes that occur on the ocean floor. Tsunamis are usually characterized by a series of very large waves, rather than a single wave.
What causes a rogue wave?
When waves formed by a storm develop in a water current against the normal wave direction
, an interaction can take place which results in a shortening of the wave frequency. This can cause the waves to dynamically join together, forming very big ‘rogue’ waves.
What do tsunamis and rogue waves have in common?
The only thing that they have in common are that
they come from water and are destructive

different swell interfering constructively
, that is two wave fields combining such that two wave crests add up to produce a much taller wave.
What’s the difference between a tsunami and a wave?
A tsunami is a series of huge waves. … Tsunamis occur as a result of
the movement of a huge volume of seawater from the seabed to the sea surface

Are rogue waves tsunamis?
