Tsunamis are waves in the sea or a lake that are created by a disturbance in the water – like the ripples created when you throw a stone into a pond. Most tsunamis are caused by earthquakes under the sea, but they can also be caused by volcanic eruptions, underwater landslides, landslides into the sea or a lake.
